Got about a thousand rounds through mine on a pws mk111. Sounds amazing; you could easily pop off a whole mag without ear pro and be OK. Flash reduction is excellent also. But even on a piston system that can is very gassy. I laughed when you brought out the gas mask 😂
Great stuff! I am excited to see more. The backpressure portion of the test dual function as a durability testing as well. Love to see same test o 308 caliber cans like the Omega 300.

I would love to see the nomad performance. I know it's not a dedicated, but is a good multi caliber can, durable, and has a face plate you can put for 556
Sierra 5 is extremely gassy due to high back pressure. I had to do several mods to manage it once I added the Sierra 5 to my 11.5”. Not as bad with the 14.5”
@scott2228 You are 100% correct. Great can for noise suppression, good size, great flash reduction but it’s gassy. Having an adjustable gas piston with this can helps a lot but its still gassier than a flow through can. Last but not least; It’s a Heavy Can. It’s traditional. I’m one of those that had the Sierra 5 Baffle issues. I sent it off and got it back in 4 months. Great can but all cans have downsides and positives.
Sorry to hear u were 1 with an issue. 4 months is right at the mark where ur starting to get frustrated. The solution…. Have several suppressors. lol. I half joke. The Sierra was my 2nd can. I’ve got a 3rd in jail. I’ve got 401 rounds through it so far. What round count were u at when it died? My understanding is it’s usually early on. Curious to know if that’s true.
@@scott2228 lol you are right again. Have several. I’m on #8. All are with me. As far as the round count, I had less than 1000 rounds on mine. I didn’t really know I had an issue until I showed the can to a DeadAir rep who was at my local range for a demo event. He looked down the baffle stack turned the can over tapped it and small pieces of baffle fell out like cracker crumbs. It wasn’t a ton of baffle stack that fell out but the Rep knew exactly what he was looking at. In the end…. Dead Air made it right. It just took a while.
That thing really sped up the 249 a lot more than what I've seen in your other tests. It also seemed pretty flashy. I do like the sound/tone of it. Too bad it was such a mess of production and service. Gotta get a polonium to try on that 249 and see how it does. Andrew warranties them for 300rd bursts of 5.56 IIRC
@RooftopDefense it's super interesting to see how much some of them glow after a 100rd dump. Don't think my poloK has gotten that bright on my 10.5 M16. Even with 60rd drum dumps
@@RooftopDefenseSpeaking of Otter Creek, I don’t know if an OCM5/AEM5 study is feasible (I know the host setup is more work) but I think that would be interesting to a lot of people. The OCM5 has really renewed/maintained interest in that design.
Surprised to not see the can become glowing red hot like the others. Any idea why? I had out of spec problems with my Sandman S can years ago. Disappointing to read about the problems others now have with the Sierra can.
It's probably due to materials. Inconel and 17-4 stainless steel is known to glow red hot and give out an intense IR signature when it's super heated however Inconel won't lose any strength at those temperatures. The Dead Air cans use Stellite which is essentially a cobalt alloy so it has completely different heating characteristics.
In addition to the matter of materials properties mentioned above (I can’t speak to the exact materials used for all of these)… It also simply comes down to Design: where and when gas is routed, and what happens afterward (in the following milliseconds). This is much of what makes different suppressors do different things because, in the end, visual and acoustic signature are just functions of Which gas leaves the suppressor and When. Cans that direct a lot of freshly hot gas through channels around their radial exterior (flow-through designs) will expose the outer wall directly to a lot of hot gas that keeps moving and fresh and hot, so flow-through cans glow fast because the hot gas is proximal to the exterior wall (the actual “can”) for much of its cooling duration, so imparts heat on that surface via conduction. Traditional baffle designs, with big pockets for gas to (literally) chill out in before getting stirred up and partially sucked out in the wake of the projectile, will see different dynamics in gas flows inside each baffle. Hot gas next to the exterior wall will of course contribute most to glow, but gas will also heat the baffle dividers, which will reduce their ability to act as heat sinks, so will add to flow a bit too. So the answer is: I have no idea :) but it’s all a function of hot gas passing thermal energy to the solid metal structure of the can, and the thermal energy of the Outside cylinder of the can being what you experience as externally visible glow. Traditional
To remain as objective and fair to every silencer as possible, I would like to omit my personal opinion on any silencer that we have or plan to rest, but there is a lot of review content publicly available from other homies though :) I'm sorry about that, dude!
Great info! I do wish you had the equipment to test the sound reduction. The decibal metering equipment I understand is expensive, but so is a SAW and Harris NVGs. A suppressor is about sound reduction, so testing a suppressor without sound reduction is akin to testing a race car by how shiny it is without testing its speed.
I’ve got a Sierra 5 with a little over 400 rounds through it. I use KeyMo with my 11.5 and Xeno on my 14.5”. Solid can so far however, it is Extremely gassy. There is a ton of back pressure.
So, exactly how common is the Sierra 5 issue? 50% of them? 10%? 2%? I’m not real clear on this. I see a lot of people COMMENT negatively but I’m more interested in factual information than dudes who have never even held a Sierra5 and are just parroting what they see other people say.
Has to be a lot of parroting especially on reddit. I know three guys that own them with no problems. Two of the guys own two a peice so thats five seirra 5s, if it was as big a problem as it seems you'd think atleast one of them would fail. That's just what I've seen personally.
@@slowmo7500 they’re starting to have problems with other warranty cans. They gotta get on their stuff or else people are going to write them off for good
It's good to see the channel growing. Great video, Sol!
We're back good, dude! And here to stay :)
You're making great content. I hope you keep making more.
Crazy to see how hot the RC3 got compared to the Sierra 5

I love this series. Keep up the great work.
Would love to see a video of this format going over the CAT WB and ODB
Great comparison with consistent testing, doesn't look cheap, would like to see the Griffen duel lock tested
Good stuff, and thanks for the ramen. Any chance we’ll be seeing the CAT suppressors tested?

Noticing a lot of gas coming out of the ejection port. Downside of traditional baffles i suppose

If its build like a sandman its because the tube on the outside is housing the baffle stack rather than a part of the baffles themselves

Hey great video. On a 556 gun do you like a muzzle brake or flash hider?
I prefer flash hiders over muzzle brakes for 5.56 rifles. For the larger calibers, it depends on the gun, haha.
