My father has tinnitus he is in late 60's. He never took care of his ears protecting them around machinery growing up because back then no one did. I feel bad for him because he says at night it drives him crazy just like constant mosquitoes buzzing in his ears. He told me he can hardly stand it and I wish i could do something to fix him. Im so use to being able to fix things when they are broken but cant fix the things most important to me unfortunately. He also drinks a lot of beer unfortunately which he has done his entire adult life to where its always been on the borderline of being a real f**king problem and i know for a fact it gets worse as he starts to get more alchohol in his system
Ray, awesome information and well presented as always. I must say I am amazed you do not have WAY more subscribers with the quality of your channel and its content. You deserve to be in the millions! Respect! Hi from NZ
Excellent presentation! I got a Huxwrx 556 Flow recently and am very pleased with it. Yes, I still wore hearing protection but the difference between using it and a naked barrel is logarithmically large. Small & lightweight too. Confirmation bias confirmed! 😂 I went to an audiologist a couple years ago because of tinnitus and mild hearing loss. He asked me a bunch of questions. Running a chainsaw without hearing protection back in the 1970s definitely was a bad idea. However, he said “Ah ha!” when I told him about the high school rifle team. Lots of .22 rifles inside even with 1970s “ear protection” explains the additional hearing loss in my left ear and the specific frequencies I can’t hear as well.
I am deciding between the B&T SRBS and the PRT Vent. Really considering the B&T inconel since they $950 and does everything the PRT does for $550 less. Also impressed how the B&T has almost no flash signiture at night time. No blow back and only increases bcg speed by 1.9%. While being quiet. Building another custom in 300blk for subs and it will be for that
NFA Review channel loved the SRBS. His review actually sold me on it, so I just ordered one (the inconel full size). I’m VERY excited to see how it performs on my 11” Bren 2
Great video! I love to see how much your channel has grown since I first started watching 6 or so years ago. I’m still an RC2 man. Eventually I’ll delve into the flow through stuff now that wait times are dramatically lower.
I really appreciate you measuring the volume of simply dropping the bolt. A lot of people likely don't understand that just the action itself on an AR is loud enough to cause hearing damage. There is, unfortunately, no such thing as a hearing safe suppressed AR, even in .300 BLK, simply because the metal-on-metal of the bolt slamming forward is too loud for regular exposure.
Well done! So much information packed in. This must have taken a lot of time and effort to make this video. Thank you. Looking ahead, I hope you can add the Sig SLX and SLH cans to your testing. They have not received much coverage on social media. I am interested in learning more about their performance and design.
Thank you for the video most people give an opinion with no substance or explanation behind it. you helped me narrow my choice down and even better I'm gonna save a little money

I competed in a night match at Clinton House this past weekend and noticed something interesting. We were shooting at targets between 100 and 200 yards for rifle, so in the white light division the gun smoke resulted in a significant challenge. There was a guy using the Huxwrx Ventum 5.56, and because of the flowthrough design he had the same issue with smoke as the people without a suppressor had. Namely, the gun smoke was illuminated by his weapon light and obscured his vision significantly because it was not trapped by the suppressor, as opposed to those of us using traditional cans. I am not sure if that was a specific issue related to the Ventum, his particular gun+can+ammo+light combination, or an issue with flow through cans in general. Just an interesting data point.
I don’t think the Ventum 556 is out yet, it was a Ventum 762? Maybe it would make a difference if it was 556 specifically? No dog in the fight, just wondering.
Great comment. I have done a lot of night matches with tons of different suppressors. I too, noticed that the reduced backpressure cans definitely vent more "smoke" out of the front. Definitely more noticeable on a calm night.
Excellent breakdown of the cans, thank you for the insight. On a side note, your three offhand hits at 500... uh please excuse me but I need to go out and hit the range more often and stop making excuses haha.
great video. as an fyi to people, the peak db can be as little as a few ms in duration or less. this comparison is useful in the relative db of cans between each other, but i wouldnt use this video to determine the absolute db of each can and whether or not its 'hearing safe' because the db meter he's using can easily miss the peak impulse and peak db wave, which could be higher, and lead to hearing damage. as he mentioned before, you need an extremely expensive db meter to accurately gauge firearms sound levels.
Correct and you are the first person to mention this issue. The Mil Std 1474 based sound meter requirements for testing silencers specifies a 20 microsecond rise time. That means the meter has to go from ambient noise to 165+ dB within 20 microseconds. The maximum clock speed of a digital sound metering system is something like 28 microseconds. It has been shown that this is sufficient to properly meter sound suppressors. The digital systems run around $10,000. There are a couple of older analog sound meters that are capable of meeting the 20 microsecond rise time but those meters are getting old now and they are still pretty expensive and hard to find. FWIW I was trained to meter sound suppressors by Alan Paulson and Phil Dater.
Ray, I just came back from the Ohio Suppressor Shoot. Got to shoot some great cans. But, for me to consider a new purchase today for 5.56 or a 7.62 can, they need to be on the Hub design. I have over $1000.00 invested in SICO ASR mounts. I can unscrew the mount section of any of the SICO cans I have and screw on to any manufacture that utilize the Hub threading design. Like Dead Air. Surefire was there, but I bypassed them for that reason. Manufactures in attendance were; Surefire, SICO, Dead Air, Sig, Q, OCL, and Rugged. Wish there some of the cans in this video in attendance to try, like the B&T.
That awesome Snakeman! The Hub definitely makes life easier but at the cost of a little more weight. Definitely something worth considering when purchasing a new suppressor.
Probably have to go with the 7.62 version then. I don't see anywhere on their page where it says the 5.56 version can handle 6mm arc. I bought an OCL polonium intentionally for that flexibility so I look for it without having to go up to a 30 cal with overbore.
Your comment about the left ear is dead on. I have massive hearing loss in my left ear. While taking the test, and doing very poorly, the ENT finally asked “are you a right handed shooter?” “I am” “I see that same result, a lot, from right handed shooters”
Hey Buddy, very informative video, thanks a lot for being thourough with each suppressor , I just bought the Rugged Alaskan 360 , should be any day now 💥💥🔫 thanks From Commy Ct.🇺🇸
Great testing. It’s nice to get a db rating even if it’s not an absolute rating it gives you a comparison between them. The Cobalt Kinetics was pretty impressive. Something to look into.
Based in larger part on this review (and others), and also based on availability, I picked up the HuxWrx. Limited usage so far, but I'm pleased with the purchase.
Hello, I have been watching as many suppressor videos, n even reading to get further info !!! N I just had to say that was a very well done video, great choice to compare !!! I just Bought the Alaskan 360 from Rugged , haven’t shot it yet , but I can’t wait to hear for real in person a suppressor in action , nothing wild cause I live in Commy Ct. n we are still under n UNCONSTITUTIONAL AWB OF 2023 n mag ban of 10 , suppressors are my only way to change it up n stay with in the outrageous illegal 2A laws !! I can’t buy the guns I want because it doesn’t feel right to put a 10 rd mag in a gun sold in a different state it comes with 2 -17 rd n 1 - 20 rd mag I get 3 after market or crimped stock mags so it’s spring is on 10rd of pressure it’s whole existence ! So I guess that answers the question of leaving mags loaded !!! Sorry I drifted !! But keep on keeping on 💥💥🔫 from Commy Ct.🇺🇸
Even just the LENGTH of the actual muzzle blast impulse from a suppressor can make a big difference. For example, a suppressor which has a higher peak db rating, might actually be less harmful to your hearing than a suppressor with a lower dB if the total length of the pulses is longer. Obviously this includes several other factors of the impulses, but a suppressor which 'stays loud' for longer can often be more damaging than a suppressor 'gets louder, but doesn't stay loud as long'
I have the Gate-Lok HUB adapter from Griffin Armament. (Works just like the B&T A2 adapter) It works great and allows me to move my Suppressor from gun to gun. It also saves money because A2 flash hiders are a lot cheaper than specific muzzle devices. The down sides are, you really need an alignment rod if you plan to use a Gate-Lok system. Because it doesn't lock onto the A2 flash hider really tightly, the suppressor moves around a lot, that made me nervous, and that's why I ordered a alignment rod, to make sure I wouldn't have a baffle strike. Glad I did too. Because it definitely would have struck the end cap. I then replaced all my crush washers with shims to help with the alignment and checked each one with an alignment rod. Second because it doesn't lock securely in place it leaks gas from the back of the suppressor. That doesn't really hurt anything but the flash hider gets really dirty.
"It works great... now lemme tell u why it's horrible and nobody should buy one." oh word thanks bro, now I know that Griffin's product is shit and I don't know why people keep buying them if that's what they're really like lol
@@rondobrondo Actually, the reason for the movement and my subsequently getting an alignment rod is because A2 flash hiders are made by virtually everyone, to varying degrees of quality control. It's actually pretty cool that they can, make it work at all. Griffin Armament makes a line of Gate-Lok muzzle devices that are built to work with it. I assume, if I had gotten those and replaced all my A2 flash hiders, I wouldn't have needed the alignment rod. Also, the reason I would have had a baffle strike is not the fault of the Gate-Lok, but because of the crush washers causing the A2 flash hiders not site concentric to the bore. Something else I noticed, since writing this. The Gate-Lok doesn't "leak gas from the back of the suppressor" like I said in this comment. What I was thinking is that it must be because the flash hider is all gunked up. But I don't see any evidence that the gas is leaking past the back of the Gate-Lok. All in all it works great! Yes, you should change out the crush washers with shims, and to do that you really should have an alignment rod, but that's not difficult, and alignment rods are not expensive. (I got a carbon fiber one made by Huxworks for $35.) If I had done that in the beginning, I wouldn't have had any of issues.
I've been debating on what to buy more than a year honestly. I shoot 7.62x39 but on an ar platform. It's just for hogs/varmint hunting. I have no real benchmark for performance, I have considered the Enticer L because it seems to have good performance for cost. But the ODB seems great. I just don't know how to justify more than double the cost. Sucks that all the places around me in TX only offer suppressors at indoor ranges lol.
Kind of surprised by the B&T having such high dB. That’s not at all the results I’ve seen, especially for the full size one. Everything I’ve seen says it has a nice deeper tone and noticeably quieter than the Flow556.
@goldrush49 Have you checked out the results from the Thunderbeast Arms Suppressor Summit 2024? They have a pulse meter and all the results from many manufacturers are in there. Including the 556k 👍🏼
@@XRING those are the results I was referencing when saying I was surprised with the B&T bc the full size did really well and the compact was on par with the OCL Polo K, which people obviously love the sound reduction especially for its size.
@@JGoodZX6R Well. I do need to do a follow up video to this. The B&T is an effective suppressor. However, since I had one of the first models early in the game, it was determined that I had a prototype mount that was not correctly sized for the suppressor. I think this is what yielded the higher numbers.
Ray, another informative video. What ear pro do you use? As many caliber and barrel lengths you shoot, I'd enjoy hearing about the ear pro you use in the videos and comps.
I keep trying to find a comparable flow through alternative to the Huxwrx flow, but it’s like they’re in a class of their own. Won’t tear up your gun and suppression is actually comparable to cans that will tear up your gun more. I guess they really are worth the hype!
@@WalterRitchey Honestly Id suggest looking up "Cat ODB pew science". They got a long review that goes over a whole lot of aspects. It is a Flow thru no blowback design. They also towards the end of the review talk about how it compares to some of the other leading suppressors on the market. In which ways it beats them and in which ways it may fall short. They also have reviews of the Hux flow 556k and 762ti. So you can read those comparisons. Pew science takes it to a very scientific level that most people dont. Cat is also very responsive on the gram so if you have any questions they usually respond w/in minutes. Cat Wb is shorter than Hux 556k. And ODB is slightly longer than Hux 556k. ODB is actually made for 7.62x39. Which means it can shoot 308/762. But is also currently Pew Sciences highest rated flow thru suppressor on the MK18 556 platform outside of the PTR vent (id prefer the ODB over the Vent due to the vents overly complex internal structures). So that would give you the additional flexibility to put it on 7.62 and 556 opposed to 556k only works on 556. Wb is also a 556 only suppressor.
@@WalterRitchey If the "flowthrough" scale was from 0-10, with Hux Flow 556 being a 10, and 0 being getting oil and grime and gas shot into your eyeballs hard enough to make you cringe, and the gun is slamming hard. The CAT cans are like an 8.5-9/10. It's very low back pressure and it has superior performance to the Hux in pretty much every way I can think of. The 'backpressure' of the CAT can is basically a non-issue and you probably wouldn't even need to tune your gun at all. If you are capable of seeing through their intentionally offputting marketing and recognizing good engineering and good product, you'll want it once you see what it's capable of for its size. And it's also a can that scales EXTREMELY WELL with barrel length. A tuned 16" with a CAT is insanely quiet and soft and clean. And you'll also realize that they go out of stock extremely quickly lol, especially the Inconel
@@rondobrondo that’s a great breakdown, appreciate it! I’m planning on suppressing the HK MR series which doesn’t have any gas adjustability so I’m leaning into Huxwrx but I know aftermarket exists and I do keep hearing great things about CAT. Agreed their marketing is a lot to get through haha.
Are any of these modular/multi-caliber? Was heavily considering a Griffin Optimus 9 as my first suppressor to have a lot of calibers up to 308 covered, but there is a large appeal for flow through suppressors, especially on DI guns.
I also wear my hearing protection on my motorcycle, the wind noise on the helmet can be very loud to the point, I would return home, turn on the TV and was unable to hear it!
B&T SRBS 556 Full Size DM just showed on Silencer Sh_p with a "free" tax stamp. It has been my experience that one pays for the stamp and then is reimbursed at the appropriate time. 👍🇺🇲
At 32:14, he says that Surefire recommends the closed tine flash hider for the best flash suppression. Correct me if Im wrong, but dont they recommend AGAINST using the closed tine because of the flash?
Just a heads up, you are using a warcomp on your mk18 which is skewing heavily your numbers on the mk18 test. Sound leaks heavily around the locking collar through the ports on the muzzle device. That is why every can you tested on the MK18 using the surefire muzzle device put out such bad numbers. Switch to a surefire 3prong or 4prong for suppression.
@@flavortown3781 You're wrong, the RC2 specifically, and probably a lot of other cans, lol, is built in such a way that the muzzle brake actually WORSENS the sound suppression performance of the RC2 compared to the Pronged flash hider. It's not a giant difference, but it is legitimately significant
My can has been in jail since april, I got the flow 762 for versatility across multiple gas guns. Gonna come back and watch this when I'm approved, don't want to be disappointed in my choice
The Flow 762 is even quieter at the muzzle on 5.56 but sacrifices a little at ear. Love the 762 on most all of the semi autos especially 7.62x39 and 6.5 grendel
Great video. I hope you address the difference the difference with bolt action and AR. A lot of loudness is increased due to the receiver opening on an AR.
I just found your channel and subscribed. What part of NC are you in? I found the channel because of a video you did on a Tract scope. I’m considering the Toris 2.5-15x44 for hunting. Do you know anything about the durability of their scopes for hunting?
Have you ever tested with a blank round. In airgun testing, tin pellets can exceed 1200 fps. Lead and alloy pellets peak at 950-989 fps. The tin pellets crack and lead pellets thump. What is the dB for a blank?
That's actually a great question.... Since there's no bullet breaking the sound barrier there should be no crack whatsoever... A bit off topic but I've personally tested how loud a centerfire style primer is outside of a firearm, "both the bullet and all powder was removed from the brass casing and was struck with a hammer & nail". I was absolutely SHOCKED at how loud just the primer itself was. It was louder than your typical Chinese firecracker.
I wonder what the difference in sound is, if any, between using a brake vs a flash hider under the can? Hux offers both for direct thread of the 556k Flow.
That’s a Larson Davis unit. If you can find an old analog B&K those actually meet the mil-std they are really old though and parts can be difficult to obtain.
I don't see anything about an inconel version of the Scrambler anywheres. Where are you getting an inconel version from and what is the weight compared to the TI version?
How did you get an Inconel Scrambler? They only have titanium on their website. Asking because i am interested in buying one. I was looking at the CGS SCI-Six as well, but cant find much info on it. Have you tried this yet??
Guys read PEW Science for actually MIL-STD testing and analysis of these suppressors. They have tested every suppressor in the video except the B&T and they have not posted the data for the Scrambler yet. Whatever the meter is saying just ignore it because it filters the the data and it doesn't sample the sound pressure fast enough so some suppressors might be louder or quieter than what's show above.
Pew Science DOES NOT test to the Mil Std. He made up his own special metering system that nobody else uses and is not supported by any other group or govt standard.
Thank you sir for telling people that none of these cans are “hearing safe”. < 140 dB is not hearing safe. It is a total lie to advertise as such. Hearing safe long ago was < 120 dB, not even < 130 dB. Repeated exposure above 120 dB means you should wear ear protection. Period.
Hearing safe is an interesting conversation once you get into the weeds on it. Your ears can safely hear different levels of sound depending on what frequency it is. Lower frequencies can get louder w/o damaging and higher frequencies especially really high it doesnt really take much to do damage. Every time your ears ring, the frequency you hear is the frequency you damaged. And youll never hear that frequency the same again. You are literally changing your ears EQ and youll never hears things the same after the ring goes away. Its typically so incremental you wont notice. Until it adds up and a particular frequency range is gone. Such as highs in the 2k-6.3k range. Ironically thats the frequencies that most suppressors dont suppress. Suddenly you have a hard time understanding people speaking because thats the range where all the intelligibility in words lie. Turn on a speaking video, dump all those frequencies in the EQ and see how hard it is to understand people speaking. And not every persons resiliency to loud noise is the same. So to use a blanket DB number as the line where hearing damage starts isnt correct. Its really person to person. It involves individual resiliency, existing hearing damage and at what frequencies, current diet, blood pressure and health, and what frequencies your suppressor is actually not suppressing (frequencies you hear when you shoot). Still looking for the brown note suppressor. Gonna take some real science to get there on that one. 🤣😉

Really appreciate the quick but relatively comprehensive background on dB measurement and hearing damage.
Excellent breakdown of the cans, thank you for the insight. On a side note, your three offhand hits at 500... uh please excuse me but I need to go out and hit the range more often and stop making excuses haha.
🇺🇸
Taking one for the team. Thank you.
LOL!. I really wanted to get the first hand experience with them without ear pro. Definitely makes a difference in my opinion of them.
Just getting into the world of suppressors, ALOT of good info here. Thank you for the video, and you gained a subscriber.
Thanks Ray, this is the video I was looking for! Great Job! 🇺🇸
I actually fake hearing damage so I can ignore some of the nonsense happening around me at work:)
🤣
Lol epic!
I do the exact same shit. Learned it from my grandfather how he did it to my grandmother and my father did to my mother
Noise cancelling ear buds
I have no respect for a faker
great video. as an fyi to people, the peak db can be as little as a few ms in duration or less. this comparison is useful in the relative db of cans between each other, but i wouldnt use this video to determine the absolute db of each can and whether or not its 'hearing safe' because the db meter he's using can easily miss the peak impulse and peak db wave, which could be higher, and lead to hearing damage. as he mentioned before, you need an extremely expensive db meter to accurately gauge firearms sound levels.
Correct and you are the first person to mention this issue. The Mil Std 1474 based sound meter requirements for testing silencers specifies a 20 microsecond rise time. That means the meter has to go from ambient noise to 165+ dB within 20 microseconds.
The maximum clock speed of a digital sound metering system is something like 28 microseconds. It has been shown that this is sufficient to properly meter sound suppressors. The digital systems run around $10,000. There are a couple of older analog sound meters that are capable of meeting the 20 microsecond rise time but those meters are getting old now and they are still pretty expensive and hard to find.
FWIW I was trained to meter sound suppressors by Alan Paulson and Phil Dater.
Wow that Cobalt can is pretty impressive for the size.
Like your videos. You provide great information in relation to what you are doing the videos about. Very much appreciated...
Ray, I just came back from the Ohio Suppressor Shoot. Got to shoot some great cans. But, for me to consider a new purchase today for 5.56 or a 7.62 can, they need to be on the Hub design. I have over $1000.00 invested in SICO ASR mounts. I can unscrew the mount section of any of the SICO cans I have and screw on to any manufacture that utilize the Hub threading design. Like Dead Air. Surefire was there, but I bypassed them for that reason. Manufactures in attendance were; Surefire, SICO, Dead Air, Sig, Q, OCL, and Rugged. Wish there some of the cans in this video in attendance to try, like the B&T.
Look at the Hux Ventus
That awesome Snakeman! The Hub definitely makes life easier but at the cost of a little more weight. Definitely something worth considering when purchasing a new suppressor.
Isn’t the B&T HUB compatible?
Great information Ray. Good to see you posting again. Have a good week sir.
Thanks Joaquin! I am trying to stay more regular with the videos when possible. Too much to review and so little time!!! Have a great week.
That B&T would look nice on my 6ARC. Maybe I’ll break down and buy one.
Probably have to go with the 7.62 version then. I don't see anywhere on their page where it says the 5.56 version can handle 6mm arc. I bought an OCL polonium intentionally for that flexibility so I look for it without having to go up to a 30 cal with overbore.
Do it. I have the SRBS762-DM on an AR15 and it’s fantastic and a great value.
The epic drama of YOU FLAGGED ME (through the camera.). 🤣😂🤣 Some people are afraidof their own shadow.
Your comment about the left ear is dead on. I have massive hearing loss in my left ear. While taking the test, and doing very poorly, the ENT finally asked “are you a right handed shooter?” “I am” “I see that same result, a lot, from right handed shooters”
Hey Buddy, very informative video, thanks a lot for being thourough with each suppressor , I just bought the Rugged Alaskan 360 , should be any day now 💥💥🔫 thanks From Commy Ct.🇺🇸
I agree with you on the left ear going deaf first. I may have been dealing with that for quite a few years.
Great testing. It’s nice to get a db rating even if it’s not an absolute rating it gives you a comparison between them. The Cobalt Kinetics was pretty impressive. Something to look into.
Based in larger part on this review (and others), and also based on availability, I picked up the HuxWrx. Limited usage so far, but I'm pleased with the purchase.
Another informative and entertaining video! Like someone else wrote, supporting the HUB system will be an important aspect when choosing my next can.
Definitely an important consideration since the cost of ownership of a suppressor is quite high when you factor in the tax stamp and accessories. 👍
Great info from you as always Ray!
Thank you olamorken and thanks for watching the channel.
Great video. You earned a subscriber today.
Great job with the comparisons. Very useful information. Subscribed!
Hello, I have been watching as many suppressor videos, n even reading to get further info !!! N I just had to say that was a very well done video, great choice to compare !!! I just Bought the Alaskan 360 from Rugged , haven’t shot it yet , but I can’t wait to hear for real in person a suppressor in action , nothing wild cause I live in Commy Ct. n we are still under n UNCONSTITUTIONAL AWB OF 2023 n mag ban of 10 , suppressors are my only way to change it up n stay with in the outrageous illegal 2A laws !! I can’t buy the guns I want because it doesn’t feel right to put a 10 rd mag in a gun sold in a different state it comes with 2 -17 rd n 1 - 20 rd mag I get 3 after market or crimped stock mags so it’s spring is on 10rd of pressure it’s whole existence ! So I guess that answers the question of leaving mags loaded !!! Sorry I drifted !! But keep on keeping on 💥💥🔫 from Commy Ct.🇺🇸
Even just the LENGTH of the actual muzzle blast impulse from a suppressor can make a big difference. For example, a suppressor which has a higher peak db rating, might actually be less harmful to your hearing than a suppressor with a lower dB if the total length of the pulses is longer. Obviously this includes several other factors of the impulses, but a suppressor which 'stays loud' for longer can often be more damaging than a suppressor 'gets louder, but doesn't stay loud as long'
Love to see what you think of the CAT WB
Working on it as we speak. Need to get one in for review.
@@XRINGI’ll send you a CAT WB if you want to try one that I have as a demo. I’m an 07/02 in Clarksville, TN. (Longbow Arms). Hit me up if you want.
I have the Gate-Lok HUB adapter from Griffin Armament. (Works just like the B&T A2 adapter) It works great and allows me to move my Suppressor from gun to gun. It also saves money because A2 flash hiders are a lot cheaper than specific muzzle devices. The down sides are, you really need an alignment rod if you plan to use a Gate-Lok system. Because it doesn't lock onto the A2 flash hider really tightly, the suppressor moves around a lot, that made me nervous, and that's why I ordered a alignment rod, to make sure I wouldn't have a baffle strike. Glad I did too. Because it definitely would have struck the end cap. I then replaced all my crush washers with shims to help with the alignment and checked each one with an alignment rod. Second because it doesn't lock securely in place it leaks gas from the back of the suppressor. That doesn't really hurt anything but the flash hider gets really dirty.
"It works great... now lemme tell u why it's horrible and nobody should buy one."
oh word thanks bro, now I know that Griffin's product is shit and I don't know why people keep buying them if that's what they're really like lol
@@rondobrondo Actually, the reason for the movement and my subsequently getting an alignment rod is because A2 flash hiders are made by virtually everyone, to varying degrees of quality control. It's actually pretty cool that they can, make it work at all. Griffin Armament makes a line of Gate-Lok muzzle devices that are built to work with it. I assume, if I had gotten those and replaced all my A2 flash hiders, I wouldn't have needed the alignment rod. Also, the reason I would have had a baffle strike is not the fault of the Gate-Lok, but because of the crush washers causing the A2 flash hiders not site concentric to the bore. Something else I noticed, since writing this. The Gate-Lok doesn't "leak gas from the back of the suppressor" like I said in this comment. What I was thinking is that it must be because the flash hider is all gunked up. But I don't see any evidence that the gas is leaking past the back of the Gate-Lok. All in all it works great! Yes, you should change out the crush washers with shims, and to do that you really should have an alignment rod, but that's not difficult, and alignment rods are not expensive. (I got a carbon fiber one made by Huxworks for $35.) If I had done that in the beginning, I wouldn't have had any of issues.
I like your work, great advice as well 👍🏿 😊
Great unbiased information and video !!!
I've been debating on what to buy more than a year honestly. I shoot 7.62x39 but on an ar platform. It's just for hogs/varmint hunting. I have no real benchmark for performance, I have considered the Enticer L because it seems to have good performance for cost. But the ODB seems great. I just don't know how to justify more than double the cost. Sucks that all the places around me in TX only offer suppressors at indoor ranges lol.
Kind of surprised by the B&T having such high dB. That’s not at all the results I’ve seen, especially for the full size one. Everything I’ve seen says it has a nice deeper tone and noticeably quieter than the Flow556.
Take it for what you will but pew science has the 556 k as one of the quieter cans at the shooters ear. A lot louder for bystanders.
@goldrush49 Have you checked out the results from the Thunderbeast Arms Suppressor Summit 2024?
They have a pulse meter and all the results from many manufacturers are in there. Including the 556k 👍🏼
@@XRING those are the results I was referencing when saying I was surprised with the B&T bc the full size did really well and the compact was on par with the OCL Polo K, which people obviously love the sound reduction especially for its size.
@@XRING would love to see the FOR Recce on your dB equipment!
@@JGoodZX6R Well. I do need to do a follow up video to this. The B&T is an effective suppressor. However, since I had one of the first models early in the game, it was determined that I had a prototype mount that was not correctly sized for the suppressor. I think this is what yielded the higher numbers.
Wish you had tested the Larue tactical Tranquillo flow through.
What kind of microphone do you use? Getting constant results of 155,9 dB for unsuppressed indicates reaching the microphone limit.
Ray, another informative video. What ear pro do you use? As many caliber and barrel lengths you shoot, I'd enjoy hearing about the ear pro you use in the videos and comps.
very impressed with the huxwrx and cobalt
Same here! Going to try to get one of the CAT's in as well.
I keep trying to find a comparable flow through alternative to the Huxwrx flow, but it’s like they’re in a class of their own. Won’t tear up your gun and suppression is actually comparable to cans that will tear up your gun more. I guess they really are worth the hype!
Cat WB or ODB. but 718 and not titanium. titanium gets wayyyyy toooo hot way too quick. ODBs in stock at silencershop right now.
@@Nate-zm6bd is the ODB the same / no blowback? In what ways is it better? Weight, size, sound?
@@WalterRitchey Honestly Id suggest looking up "Cat ODB pew science". They got a long review that goes over a whole lot of aspects. It is a Flow thru no blowback design. They also towards the end of the review talk about how it compares to some of the other leading suppressors on the market. In which ways it beats them and in which ways it may fall short. They also have reviews of the Hux flow 556k and 762ti. So you can read those comparisons. Pew science takes it to a very scientific level that most people dont. Cat is also very responsive on the gram so if you have any questions they usually respond w/in minutes. Cat Wb is shorter than Hux 556k. And ODB is slightly longer than Hux 556k. ODB is actually made for 7.62x39. Which means it can shoot 308/762. But is also currently Pew Sciences highest rated flow thru suppressor on the MK18 556 platform outside of the PTR vent (id prefer the ODB over the Vent due to the vents overly complex internal structures). So that would give you the additional flexibility to put it on 7.62 and 556 opposed to 556k only works on 556. Wb is also a 556 only suppressor.
@@WalterRitchey If the "flowthrough" scale was from 0-10, with Hux Flow 556 being a 10, and 0 being getting oil and grime and gas shot into your eyeballs hard enough to make you cringe, and the gun is slamming hard. The CAT cans are like an 8.5-9/10. It's very low back pressure and it has superior performance to the Hux in pretty much every way I can think of. The 'backpressure' of the CAT can is basically a non-issue and you probably wouldn't even need to tune your gun at all. If you are capable of seeing through their intentionally offputting marketing and recognizing good engineering and good product, you'll want it once you see what it's capable of for its size. And it's also a can that scales EXTREMELY WELL with barrel length. A tuned 16" with a CAT is insanely quiet and soft and clean. And you'll also realize that they go out of stock extremely quickly lol, especially the Inconel
@@rondobrondo that’s a great breakdown, appreciate it! I’m planning on suppressing the HK MR series which doesn’t have any gas adjustability so I’m leaning into Huxwrx but I know aftermarket exists and I do keep hearing great things about CAT. Agreed their marketing is a lot to get through haha.
Are any of these modular/multi-caliber? Was heavily considering a Griffin Optimus 9 as my first suppressor to have a lot of calibers up to 308 covered, but there is a large appeal for flow through suppressors, especially on DI guns.
I also wear my hearing protection on my motorcycle, the wind noise on the helmet can be very loud to the point, I would return home, turn on the TV and was unable to hear it!
Oh man!! I know all about that. Wind noise in a helmet for a long ride can definitely damage the hearing.
@@XRING new bike day tomorrow, PX my Yamaha FZ6-S2 for a new Yamaha XSR900 😊
@@jonhewitt3 Awesome! I just picked up a pre-owned 1200GSA. Time to get to riding .
@@XRING That's a badass bike dude. I too enjoy the adventure bike and those BMW's are great to own as long as you do the maintenance religiously :3
Thank You Sir! I liked the comparison of the suppressors on the two barrel lengths. 👍🇺🇲
B&T SRBS 556 Full Size DM just showed on Silencer Sh_p with a "free" tax stamp. It has been my experience that one pays for the stamp and then is reimbursed at the appropriate time. 👍🇺🇲
Whoa, I just scrolled down the news letter and the B&T SRBS 762 Full Size DM also is offered with free tax stamp! 👍🇺🇲
Excellent experiment
At 32:14, he says that Surefire recommends the closed tine flash hider for the best flash suppression. Correct me if Im wrong, but dont they recommend AGAINST using the closed tine because of the flash?
Just a heads up, you are using a warcomp on your mk18 which is skewing heavily your numbers on the mk18 test. Sound leaks heavily around the locking collar through the ports on the muzzle device. That is why every can you tested on the MK18 using the surefire muzzle device put out such bad numbers. Switch to a surefire 3prong or 4prong for suppression.
Sfmb is the better device for sound, the. 3 and 4 prongs are better for flash suppression
@@flavortown3781 You're wrong, the RC2 specifically, and probably a lot of other cans, lol, is built in such a way that the muzzle brake actually WORSENS the sound suppression performance of the RC2 compared to the Pronged flash hider. It's not a giant difference, but it is legitimately significant
Very helpful and thorough. Thank you...
Why take ear pro off for short barrel test ? Thanks for video but dang, it hurt me watching you do that to yourself
Wait,.... my truck audio does a 162db before the windshield lets go. My midbass in the doors is a 143db at 80hz. So any can would be amazing to me.
I just picked up my first 5.56 HUXWORKS can two weeks ago
My can has been in jail since april, I got the flow 762 for versatility across multiple gas guns. Gonna come back and watch this when I'm approved, don't want to be disappointed in my choice
Hux makes very good cans. I completely forgot that I have a 7.62 Hux as well. I should have added that to the test as well. DANG IT!
The Flow 762 is even quieter at the muzzle on 5.56 but sacrifices a little at ear. Love the 762 on most all of the semi autos especially 7.62x39 and 6.5 grendel
@JNOSNOW hoping I'll love my ventum 762 on 300 blk . As a southpaw the thought of less gas in my face makes me happy
Thanks for doing this test.
How do the CAT suppressors fit in with all this? Where do they rank relative to these?
I've been curious about cobalt can. I've only seen the tin version for sale anywhere.
is the B&T Print-X ROTEX 556 FULL SIZE also good (it comes with a Rotex-SF Titanium HUB assembly)? or B&T SRBS 556 is the way to go?
Great video. I hope you address the difference the difference with bolt action and AR. A lot of loudness is increased due to the receiver opening on an AR.
Thanks Gary! I will on some follow up videos. Trying to get some more suppressors in for the next review of them.
I’d really like to know how long each silencer will last. I know people hate on SureFire but those cans will last basically forever.
I’m debating between the 😢CobalB& , CAT MOB, or SBS
27:00 what's with that light placement? looks terrrrible to shoot. some benefit Idk about?
I just found your channel and subscribed. What part of NC are you in? I found the channel because of a video you did on a Tract scope. I’m considering the Toris 2.5-15x44 for hunting. Do you know anything about the durability of their scopes for hunting?
Thanks WR! I’m in Western NC west of Asheville .
They have a great warranty and their scopes are very robust.
@@XRING It’s beautiful out there! I’m close to Hickory.
@@NCWoodlandRoamer Nice! You are right there by Zero Delta and US Optics.
@@XRING Wow! Never heard of them, thanks for the heads up. Looking them up now!
Ahh objective testing. Wonderful.
Have you ever tested with a blank round. In airgun testing, tin pellets can exceed 1200 fps. Lead and alloy pellets peak at 950-989 fps. The tin pellets crack and lead pellets thump. What is the dB for a blank?
That's actually a great question.... Since there's no bullet breaking the sound barrier there should be no crack whatsoever...
A bit off topic but I've personally tested how loud a centerfire style primer is outside of a firearm, "both the bullet and all powder was removed from the brass casing and was struck with a hammer & nail". I was absolutely SHOCKED at how loud just the primer itself was. It was louder than your typical Chinese firecracker.
Hi Ray and others. What electronic hearing protection do you use?
I use the Otto ears Noize Barriers the majority of the time. 👍🏼
I wonder what the difference in sound is, if any, between using a brake vs a flash hider under the can? Hux offers both for direct thread of the 556k Flow.
Anywhere from 1.5db to 3.7db between a break and a simple flash hider. Brakes "for the most part" create a more uniform gas seal.
Outstanding video
300 blackout with subsonic ammo meters quieter than the exhaust on my duramax id say that’s not causing hearing damage and that’s an ar platform
Man I love this I love when you do can stuff
Thanks Will. I like to review them as well but it does make for longer and more involved video reviews.
Hey Ray, what device were you using to measure the decibels? I plan on getting one!
That’s a Larson Davis unit.
If you can find an old analog B&K those actually meet the mil-std they are really old though and parts can be difficult to obtain.
Where is the Sig Flow Through suppressor? Can you compare the PTR and Sig Flow Through suppressors to the HUX?
I don't see anything about an inconel version of the Scrambler anywheres. Where are you getting an inconel version from and what is the weight compared to the TI version?
How did you get an Inconel Scrambler? They only have titanium on their website. Asking because i am interested in buying one. I was looking at the CGS SCI-Six as well, but cant find much info on it. Have you tried this yet??
Would love to get my own as I used one in Law Enforcement. No retired but I see this as gun registration by proxy. Any thoughts?
The bolt closing can cause hearing damage? Tell that to a construction worker. You may have say it louder.
So the B&T is not possible to have on a muzzle break? Am i correct? Thanks!
Why do you say that?
@ it was a question
Which would you say sounded better/more comfortable to your ear? The Huxwrx or the B&T SRBS?
For the platforms tested in this video my ears liked the Huxwrx. 👍🏼
What's the weight on the inconel version of the cobalt? I can seem.to.find info on it
Why is the first round fired through a suppressor so much louder than the 2nd & 3rd?
Gas build up from the first shot.
Guys read PEW Science for actually MIL-STD testing and analysis of these suppressors. They have tested every suppressor in the video except the B&T and they have not posted the data for the Scrambler yet. Whatever the meter is saying just ignore it because it filters the the data and it doesn't sample the sound pressure fast enough so some suppressors might be louder or quieter than what's show above.
Pew Science DOES NOT test to the Mil Std. He made up his own special metering system that nobody else uses and is not supported by any other group or govt standard.
Can we get a velos review
So sad you guys have those crazy silencer laws. They save hearing, reduce recoil, and don't scare game as much when hunting.
Tell me about it!
Thanks for a great video. Please, there is no need for you to go unprotected. We want to minimize damage to you.
Most of those tested will shine on the shorter barrel rifles.
Did you watch the entire video?!? All of these suffered GREATLY when taken from 16" to 10" rifle....
Heads up move on using inconel on the cobalt for the dark test. The titanium scramblers are like metal sparklers until they break in good.
This man sacrificing himself for us. 😁
Thank you sir for telling people that none of these cans are “hearing safe”. < 140 dB is not hearing safe. It is a total lie to advertise as such. Hearing safe long ago was < 120 dB, not even < 130 dB. Repeated exposure above 120 dB means you should wear ear protection. Period.
Hearing safe is an interesting conversation once you get into the weeds on it. Your ears can safely hear different levels of sound depending on what frequency it is. Lower frequencies can get louder w/o damaging and higher frequencies especially really high it doesnt really take much to do damage. Every time your ears ring, the frequency you hear is the frequency you damaged. And youll never hear that frequency the same again. You are literally changing your ears EQ and youll never hears things the same after the ring goes away. Its typically so incremental you wont notice. Until it adds up and a particular frequency range is gone. Such as highs in the 2k-6.3k range. Ironically thats the frequencies that most suppressors dont suppress. Suddenly you have a hard time understanding people speaking because thats the range where all the intelligibility in words lie. Turn on a speaking video, dump all those frequencies in the EQ and see how hard it is to understand people speaking. And not every persons resiliency to loud noise is the same. So to use a blanket DB number as the line where hearing damage starts isnt correct. Its really person to person. It involves individual resiliency, existing hearing damage and at what frequencies, current diet, blood pressure and health, and what frequencies your suppressor is actually not suppressing (frequencies you hear when you shoot). Still looking for the brown note suppressor. Gonna take some real science to get there on that one. 🤣😉
