The DoD isn't releasing much information about that round's capabilities but the claims are ambitious, hence Adept pulled out all the cards for this plate while keeping it at a reasonable weight to try to accommodate absolute worst case scenario. That +P+ M993 load is just nasty to think about and if the AP 6.8 load is anything close to that, this plate really is "future-proofed" as they call it.

I just found your channel. And right at the beginning I knew I needed to sub to it. This is the most scientific test I've seen to date in regards to testing body armor. Body armor is the last big purchase I need to make. I run a Tac vest with my gear attached. But it's just a vest with no protection. I need both. My vest consist of 4 pouches for pistol mags. One I use for a multi tool, Holster for a second pistol, 3 AR mags, Phone pouch, FlashLight pouch, and a batton slot. There's plenty of molle for my hand cuffs, Battle knife and anything else I want to attach. But adding that to a plate carrier may be too much weight for me. You know what I have so you should know what I need. I'm in Texas so that means we shoot BIG guns down here. I look forward to future videos and a recommendation for the right plate carrier. I would be willing to move from my vest to a plate vest with all the needed places for my gear. Thank you for this test and your work that so far beats out everything else I've seen. Good job!!!
Considering this plates performance when it’s compromised,I think you’d have to punch a fresh plate while wearing the Infinity Gauntlet to penetrate it. Super impressive performance here.
This is your best video (at least that I have seen)! Quite a while ago, when you first discovered the Smk-H, I commented that you had found the best AP that you would likely ever find and I got no feedback. Maybe you will believe me now. I noted then that I had shot it at well over 4,000 fps (when turned down to. .308" in the equivalent to a. .300 Chey-tac (a .30/.505 Improved Gibbs))! The projectiles handled that platform easily and I still have a 3" thick cold rolled plate with two complete penetrations and shredded a 3" thick seasoned oak capture block! When fired out of a. .30 caliber propellent gun with ~ 500 grs. of IMR 7828 at over 5,000 fps...it completely penetrated a 2" thick block of Inconel (a very expensive super-alloy) that easily stopped multiple rounds of 20mm Lahti anti-tank AP ammunition! With all that being said, I never had chronographed the original ammunition! This was all done back in the mid 1980's... and I haven't seen anything yet that will best the Smk-H, but there have been a few approaches using new technologies with novel carbon structures that could possibly exceed it's performance! Thanks for filling that gap. My interests were mostly in the area of armor arrays and vehicles, and the limits of internal, exterior and terminal ballistics... and the curiosities in those areas have largely been satisfied. Thanks again for all of your excellent work, I don't know how you could have done better than you did in this video. Take care and as always, keep your powder dry!
Cheryl, I am not sure if I ever saw your reply. UA-cam is absolutely horrible about proper notifications for replies or comments, so I apologize, as I try to respond to as many comments as possible. I'm guessing you don't have anymore of those SMKH rounds left? Adept thinks this WHA tungsten may be advantageous for ceramic penetration over Wc-Co cores being used today. It's simply downright amazing to throw these at 2900+ fps from the 23" Mauser
@@BuffRANGE No I don't. I missed out on the link you had and even wondered about what you ever did with the few duds that you encountered! As I indicated in my first comment, I pretty much accomplished everything that I was curious about with these as well as the limits of propellent driven gun designs... either via my own testing or through contacts with some of the top people that I met at conferences that I attended that were either DOD or contractors/liaisons...at ADPA/NDIA or Aberdeen PG... working groups, et al... Some of the contacts came from 'filtered' responses to some articles that I have written in several magazines that ended up being very helpful over the years... that came out of extrapolations that I made when I was running into the velocity limits of the chronographs that I was using at the time. They included upper echelon or director level people at various research facilities, to include Small Caliber sector arsenals and EML labs... and APG as noted previously. They included (invited) tours at Aberdeen, University of Texas (Austin)/EML St. Marks (via FCSA/Olin) and numerous conferences via ADPA/NDIA... Very briefly (in case you are interested)... some of those 'limits' are engineering/materials... type limits. Others are harder or more intractable. Interior ballistics: > Hyper-velocity gouging...(see: possible resolution via bore/projectile hardness tailoring... though I have not seen it fielded yet... which could be due to classification or further difficulties. What I have seen is an increase in penetrator mass which could also be limited by the launch dynamics of APFSDS/DA long rods. Future development in the direction of penetration enhancement could come from segmented long rods and the possible use of various extremely robust forms of carbon geometries from the standpoint of impact tolerance and melting points. To the question of achievable velocities... - (In atmosphere) gouging will start to occur in the low to mid 6,000 fps range (for sliding contact projectiles). Keep an eye on tank gun velocity improvements though it is likely that any break throughs will be classified, I have the feeling that there is still something holding things up. You can probably keep an eye on the fielding of promised ship-based EML platforms for this area of launch technology! As far as EML goes...there are some rather interesting launch dynamics outcomes... using velocity enhancement of pre-accelerated projectiles which has to do with the sound speed of the materials under study. The sound speed determines the speed limit of materials response. You can also encounter this once projectile speed reaches the hydro-dynamic regime (which can also be affected by density parameters). At these velocities the communication of stresses normally influencing the projectiles, goes away (I e.- the projectile does not recognize the stress occurring at the nose-tip...in the impact framework). The same consideration applies in the pre-acceleration case. In conversation with a national government lab... accelerations involving loads of over 5 times the normal yield strength were mentioned. How far beyond 5 times he could not comment on. Aero-thermal limits are another limiting factor. Tungsten long rods will encounter degrading ablation in the 3 - 3.5 km/sec. velocity regime. Adding carbon (see above) nose-tips will get you to 4 km/sec! Lastly, in my tests with high pressure propellent guns (in the early to mid 1990's) I ran through ~ a half dozen .30 and .50 caliber barrels (both rifled and smooth- bore) before reaching out to the various labs for answers. All shots in the mid 6,000 ft/second range resulted in in - bore projectile failures! End of barrel and the failure to notice the gouges will be memorable! I know that this ended up being a little beyond brief... but you seem to be on the curious side, as am I! Take care and keep your powder dry!
@@cheryltysver4819 4 kilometers per second? I am thoroughly perplexed if that is the legit speed of a projectile achievable out of something a human holds.
@@aloofsive1140 Those tests were conducted between 25 - 30 years ago and garnered far more attention than you almost certainly would ever want due in large part, to being published in a national/international venue. To your question... while the gun could be held rather easily, when operating at the maximum pressures for which it was designed, you most certainly would not want to be in close proximity! To quote the various DOD researchers that had experience with such guns, even with all the instrumentation that they had at their disposal, such guns could be very unpredictable and very short gun and barrel lifetimes were the norm (25 - 30 shots being not unusual)! Projectile failures for the various types tested were running between 85 - 90% and pressures were likely in the 200 - 250,000 + psi range (high enough to vaporize the front half of a fifty caliber cartridge case that became necessary after only twenty or so shots due to eight to nine inches of throat erosion). In the light weight projectile tests multiple .30 and .50 caliber test barrels were damaged in the first few shots due to hyper-velocity gouging when velocities exceeded the mid 6,000 - 6,500 fps range with L/D: 1 monolithic solids! The highest velocity recorded was just over 7,100 fps at the muzzle (6,980 over the Oehler 35P chronograph sensors)! Both the gun and 45" M2HB barrel were damaged during the shot! With respect to the 4km/sec. velocities... those were cited in a NDIA conference that concerned measures that were necessary to cope with aero-thermal heating/melting of tungsten and carbon tipped tungsten long rod projectiles using non-conventional acceleration methodologies that were linked to next generation launch systems in the neighborhood of twenty years ago while I was consulting with a working group out of Aberdeen Proving Ground via ADPA/NDIA.
@@jonboy9734 already made a comment on that. I mostly likely have to replace my rbav which sucks. Any recommendations? Proper fit is most important like making sure there is no excess bounce that could cause unnecessary wear on my back. I already have serious back issues.
The titanium by itself will not stop rifle rounds. It works in conjunction with a thicker UHMWPE. The titanium plate itself is good for IIIA and spike resistance.
This is the first video I have seen from your channel and I really like the way you test and this was a very interesting and entertaining video to watch, I'm definitely subscribing to see more.
Amazing content, easily the best armor testing on UA-cam. How exactly do you get your hands on some of these rounds? You obviously can’t just order them online
I had a Turkish 8mm Mauser when I was a young teenager and shot that old milsurp FMJ ammo in the green bandolier, it would easily breeze thru multiple full size trees and it even shot completely thru a 78ish old car. Straight thru the engine block and out the trunk, no doubt 30-06 is extremely powerful but that 8mm just works lol. Could you imagine having an mg-42 fired at you in the 40's, thankfully we don't have to cuz I for one would not want that to happen lol. Really glad you threw in that 8mm you don't hear much being said about that rifle or round much these days, not everything new is better than old.
@@BuffRANGE it's amazing how things change over time lol to bad I didn't order cases and cases of those and the ammo back when it was dirt cheap 🤣 if i would have been older during that time I sure would have lol
Mr. Hoffman, someday I'm gonna send you a plate that could stop that antique tungsten alloy. Fingers crossed! Also their Mantis plate is impressive in it's own way, could probably stop a steel core magdump like an AR500 plate stops a lead core magdump.
When the plate is curved... shouldn't they clay be shaped to the curviture of the plate, in order to simulate how the curved plate would be against the human body.
Adept is hands down, one of the most underrated armor companies out there. They are constantly innovating and pushing the envelope for personal armor. Oh and that plate is only like 650 usd also.

LOL I just love your 200 mag AP rounds, ethey should give the plate a solid test. But I always thought that a .50 BMG loaded with the M2 .30 AP as a sabot in a teflon sleve. Sort of like Remington's "accelerator" rounds. Now that round would give any armor a bad day
The test results are impressive! I almost bought a set, but then noticed it is actually 1" shorter than RMA 1192 and Hesco 4601 M. Colossus is 9.5 x 11.5. RMA 1192/Hesco 4601 are 9.5 x 12.5. So, I went with RMA 1192 for coverage instead and ended up paying 100$ more than for Colossus with a "poor content creator" discount :( I just wish Adept offered a larger plate.
I would hope they would venture into SAPI sizing at some point as their materials and workmanship are working. You can't go wrong with the 1192's though. I have a video of them if you didn't see it: ua-cam.com/video/PQAddn1bRcQ/v-deo.html
@@BuffRANGE Yep. I made my choice after watching your 1192 test. FYI, I wasn't able to use buffman code for RMA 1192 purchase since plates are currently on sale and they don't allow coupons on top of that.
Great video thanks. We need videos like this if anybody is expected to pay over 600 for a plate...this way we at least know what we get for the 600 price
@@BuffRANGE I prefer layers of 3a in clothing. Like my bulletproof coat. A plate takes preparation...a coat you wear every day is already on your back. I would maybe get 2 of these plates to throw into my double tall backpack 🎒 that holds my MK18. Other plates are almost 20lbs ....these plates would only be like 10lbs. Makes a big difference when the bag is loaded up and heavy.
I'd like to see companies put thin metal inserts into plates, perhaps before the UHMPWE backer, to help contain backface deformation. NIJ standards for deformation are way too lenient methinks.
Only thing I would like to see is them develop some of this new metallic ceramic foam stuff that they are now producing and working with. It both absorbs and breaks up most every penetrating round they throw at it and seems to have huge potential combined with other technology.
@@BuffRANGE it’s not as complicated as u think. Several ways to diy it even. It’s all about getting temp and cooling right. But several methods to produce it. The next is incorporating high entropy alloys into the foam.
It would be so interesting to see how this performs against XM1158. My guess is it would go through because the XM1158 bullet construction is supposed to be some new improved magical tungsten carbide in addition to having exposed tip which supposedly aids tungsten penetration.
@@BuffRANGE I had AI do some research this is what it told me: When focusing strictly on ceramic armor penetration capability, research suggests that exposed tungsten penetrators are generally more effective than non-exposed penetrators. Here’s why: Penetration Mechanism: Immediate Impact: Exposed tungsten penetrators have a direct and immediate interaction with the ceramic surface. The high density and hardness of tungsten carbide allow it to initiate shattering of the ceramic layer upon impact. This immediate interaction maximizes the initial penetration effectiveness, creating a more significant breach in the ceramic armor. Studies indicate that the direct exposure of the tungsten core increases the likelihood of defeating the ceramic layer quickly because there is no intermediary material (like a copper jacket) that needs to be penetrated first (SpringerLink) (Wikipedia) . Energy Transfer: Exposed penetrators can transfer kinetic energy more efficiently directly to the ceramic material, enhancing the penetration effect. The absence of a softer metal jacket means that more of the projectile's kinetic energy is focused on the ceramic layer, leading to more effective penetration (Refractory Metals and Alloys) (Wikipedia) . Comparative Analysis: Exposed Tungsten Penetrators: Immediate engagement with the ceramic material. Higher probability of shattering the ceramic layer upon impact. More efficient transfer of kinetic energy directly to the armor. Non-Exposed Tungsten Penetrators (Jacketed): The initial impact is cushioned by the jacket material, which can slightly reduce the immediate penetration effectiveness. The tungsten core is protected during flight and initial impact, potentially preserving its integrity for deeper penetration after initial contact. Despite these benefits, the initial interaction with the ceramic layer is less aggressive compared to exposed penetrators (SpringerLink) (Wikipedia) . Conclusion: Based on available research and documented performance characteristics, exposed tungsten penetrators are more effective in terms of purely penetrating ceramic armor. This effectiveness stems from their ability to directly impact and shatter the ceramic material, leading to better penetration outcomes. Therefore, if the primary goal is to maximize ceramic armor penetration capability, exposed tungsten penetrators are the preferred choice.
Always love your work, Buffman! Keep it up! An impressive plate for sure! I understand why you didn't shoot the SMKH first, but I wonder if a fresh uncompromised plate would have had a chance at stopping it. Unlikely, but it makes me wonder 🤔 maybe if you get another one. Haha

The DoD isn't releasing much information about that round's capabilities but the claims are ambitious, hence Adept pulled out all the cards for this plate while keeping it at a reasonable weight to try to accommodate absolute worst case scenario.
That +P+ M993 load is just nasty to think about and if the AP 6.8 load is anything close to that, this plate really is "future-proofed" as they call it.
I think it's closer to a boutique offering. If you need a sniper plate/are worried about some unknown threat, here's your deal.
A civil grade XSAPI is no joke!
At first i was put off by the flex, by nature i am skeptical, i stuck it out and was impressed by your knowledge of reloading and ballistics, the in-depth review of the armor and your display of subject based experience kept me interested and the final inspection and conclusion left me satisfied.
Subbed, thumbs-up and a bell click for you, good day Sir.
Thank you for sticking around for the end! I can be goofy at times but do try to remain info/education centric :)
thanks matt, ill take this video as a birthday gift. yes that plate is now the king of armor.
Ohh it's your birthday today?
@@BuffRANGE no but close enough. thanks.
Buddy you have by far the best and most true body armor test on the net period... you're as close as 1 can get to the NIJ we regulars can get to... thank you for all the time and effort you put into these videos...
The more I watch Matt's videos the more impressed I am with how scientific and fair and entertaining he is. Is Matt dry? He is and will be even in the biggest hurricane and that's a compliment
I just found your channel. And right at the beginning I knew I needed to sub to it. This is the most scientific test I've seen to date in regards to testing body armor. Body armor is the last big purchase I need to make. I run a Tac vest with my gear attached. But it's just a vest with no protection. I need both. My vest consist of 4 pouches for pistol mags. One I use for a multi tool, Holster for a second pistol, 3 AR mags, Phone pouch, FlashLight pouch, and a batton slot. There's plenty of molle for my hand cuffs, Battle knife and anything else I want to attach. But adding that to a plate carrier may be too much weight for me. You know what I have so you should know what I need. I'm in Texas so that means we shoot BIG guns down here. I look forward to future videos and a recommendation for the right plate carrier. I would be willing to move from my vest to a plate vest with all the needed places for my gear. Thank you for this test and your work that so far beats out everything else I've seen. Good job!!!
Old school still works...glad I have a Mauser. Thanks for the test!
That plate is both JACKED and CRACKED.
Considering this plates performance when it’s compromised,I think you’d have to punch a fresh plate while wearing the Infinity Gauntlet to penetrate it.
Super impressive performance here.
I like how scientific this channel is
#forscience!
I just don’t understand why this channel doesn’t have a million subscribers.
I wish it did too! - Also not sure why I wasn't alerted to this comment.
This is your best video (at least that I have seen)! Quite a while ago, when you first discovered the Smk-H, I commented that you had found the best AP that you would likely ever find and I got no feedback. Maybe you will believe me now. I noted then that I had shot it at well over 4,000 fps (when turned down to. .308" in the equivalent to a. .300 Chey-tac (a .30/.505 Improved Gibbs))! The projectiles handled that platform easily and I still have a 3" thick cold rolled plate with two complete penetrations and shredded a 3" thick seasoned oak capture block! When fired out of a. .30 caliber propellent gun with ~ 500 grs. of IMR 7828 at over 5,000 fps...it completely penetrated a 2" thick block of Inconel (a very expensive super-alloy) that easily stopped multiple rounds of 20mm Lahti anti-tank AP ammunition! With all that being said, I never had chronographed the original ammunition! This was all done back in the mid 1980's... and I haven't seen anything yet that will best the Smk-H, but there have been a few approaches using new technologies with novel carbon structures that could possibly exceed it's performance! Thanks for filling that gap.
My interests were mostly in the area of armor arrays and vehicles, and the limits of internal, exterior and terminal ballistics... and the curiosities in those areas have largely been satisfied. Thanks again for all of your excellent work, I don't know how you could have done better than you did in this video. Take care and as always, keep your powder dry!
Cheryl, I am not sure if I ever saw your reply. UA-cam is absolutely horrible about proper notifications for replies or comments, so I apologize, as I try to respond to as many comments as possible. I'm guessing you don't have anymore of those SMKH rounds left?
Adept thinks this WHA tungsten may be advantageous for ceramic penetration over Wc-Co cores being used today. It's simply downright amazing to throw these at 2900+ fps from the 23" Mauser
@@BuffRANGE
No I don't. I missed out on the link you had and even wondered about what you ever did with the few duds that you encountered!
As I indicated in my first comment, I pretty much accomplished everything that I was curious about with these as well as the limits of propellent driven gun designs... either via my own testing or through contacts with some of the top people that I met at conferences that I attended that were either DOD or contractors/liaisons...at ADPA/NDIA or Aberdeen PG... working groups, et al...
Some of the contacts came from 'filtered' responses to some articles that I have written in several magazines that ended up being very helpful over the years... that came out of extrapolations that I made when I was running into the velocity limits of the chronographs that I was using at the time.
They included upper echelon or director level people at various research facilities, to include Small Caliber sector arsenals and EML labs... and APG as noted previously.
They included (invited) tours at Aberdeen, University of Texas (Austin)/EML St. Marks (via FCSA/Olin) and numerous conferences via ADPA/NDIA...
Very briefly (in case you are interested)... some of those 'limits' are engineering/materials... type limits. Others are harder or more intractable.
Interior ballistics: > Hyper-velocity gouging...(see: possible resolution via bore/projectile hardness tailoring... though I have not seen it fielded yet... which could be due to classification or further difficulties. What I have seen is an increase in penetrator mass which could also be limited by the launch dynamics of APFSDS/DA long rods. Future development in the direction of penetration enhancement could come from segmented long rods and the possible use of various extremely robust forms of carbon geometries from the standpoint of impact tolerance and melting points.
To the question of achievable velocities...
- (In atmosphere) gouging will start to occur in the low to mid 6,000 fps range (for sliding contact projectiles). Keep an eye on tank gun velocity improvements though it is likely that any break throughs will be classified, I have the feeling that there is still something holding things up. You can probably keep an eye on the fielding of promised ship-based EML platforms for this area of launch technology!
As far as EML goes...there are some rather interesting launch dynamics outcomes... using velocity enhancement of pre-accelerated projectiles which has to do with the sound speed of the materials under study. The sound speed determines the speed limit of materials response. You can also encounter this once projectile speed reaches the hydro-dynamic regime (which can also be affected by density parameters).
At these velocities the communication of stresses normally influencing the projectiles, goes away (I e.- the projectile does not recognize the stress occurring at the nose-tip...in the impact framework). The same consideration applies in the pre-acceleration case. In conversation with a national government lab... accelerations involving loads of over 5 times the normal yield strength were mentioned. How far beyond 5 times he could not comment on.
Aero-thermal limits are another limiting factor. Tungsten long rods will encounter
degrading ablation in the 3 - 3.5 km/sec. velocity regime. Adding carbon (see above)
nose-tips will get you to 4 km/sec!
Lastly, in my tests with high pressure propellent guns (in the early to mid 1990's)
I ran through ~ a half dozen .30 and .50 caliber barrels (both rifled and smooth- bore) before reaching out to the various labs for answers. All shots in the mid 6,000 ft/second range resulted in in - bore projectile failures! End of barrel and the failure to notice the gouges will be memorable!
I know that this ended up being a little beyond brief... but you seem to be on the curious side, as am I!
Take care and keep your powder dry!
@@cheryltysver4819 4 kilometers per second? I am thoroughly perplexed if that is the legit speed of a projectile achievable out of something a human holds.
@@aloofsive1140 Those tests were conducted between 25 - 30 years ago and garnered far more attention than you almost certainly would ever want due in large part, to being published in a national/international venue. To your question... while the gun could be held rather easily, when operating at the maximum pressures for which it was designed, you most certainly would not want to be in close proximity! To quote the various DOD researchers that had experience with such guns, even with all the instrumentation that they had at their disposal, such guns could be very unpredictable and very short gun and barrel lifetimes were the norm (25 - 30 shots being not unusual)! Projectile failures for the various types tested were running between 85 - 90% and pressures were likely in the 200 - 250,000 + psi range (high enough to vaporize the front half of a fifty caliber cartridge case that became necessary after only twenty or so shots due to eight to nine inches of throat erosion). In the light weight projectile tests multiple .30 and .50 caliber test barrels were damaged in the first few shots due to hyper-velocity gouging when velocities exceeded the mid 6,000 - 6,500 fps range with L/D: 1 monolithic solids! The highest velocity recorded was just over 7,100 fps at the muzzle (6,980 over the Oehler 35P chronograph sensors)! Both the gun and 45" M2HB barrel were damaged during the shot!
With respect to the 4km/sec. velocities... those were cited in a NDIA conference that concerned measures that were necessary to cope with aero-thermal heating/melting of tungsten and carbon tipped tungsten long rod projectiles using non-conventional acceleration methodologies that were linked to next generation launch systems in the neighborhood of twenty years ago while I was consulting with a working group out of Aberdeen Proving Ground via ADPA/NDIA.
Quite impressive I'd take it over a lot of 5.56 and 7.62 plates that are just as thick and heavy that do a lot less
Definitely the plate I am going to buy to replace my TSG level 4 si. I'll buy it sometime early next year.
Just be sure you have a carrier that will fit it. It’s thicker than any plate I’ve ever seen.
@@jonboy9734 already made a comment on that. I mostly likely have to replace my rbav which sucks.
Any recommendations? Proper fit is most important like making sure there is no excess bounce that could cause unnecessary wear on my back. I already have serious back issues.
This is probably the best or highest threat plate I've ever seen...
You are definitely not wrong :D
And its not NIJ certified?! Damnit! Should that keep me from buying it?
The fact there isnt atleast 4 30 cal holes in the back of that plate tells u how good it is
What an amazing plate!🙏
640 per plate is a really good deal for these
Appreciate your work happy thanksgiving.
Happy Thanksgiving to you too!
Very well done brother! And I loved the funny uncle,Roger cameo! Too funny! Thanks for the great job!
Thanks for watching
Cant wait to see their titanium plate!
I should ask them about testing that model. :D
The titanium by itself will not stop rifle rounds. It works in conjunction with a thicker UHMWPE.
The titanium plate itself is good for IIIA and spike resistance.
That SMKH is really insane
That 2900 fps is no JOke
This is the first video I have seen from your channel and I really like the way you test and this was a very interesting and entertaining video to watch, I'm definitely subscribing to see more.
Thank you! It can be repetitive at times but if you're out hunting for plate info, it can be very useful!
Wow that plate was insanely impressive 👍
Indeed!
Amazing content, easily the best armor testing on UA-cam. How exactly do you get your hands on some of these rounds? You obviously can’t just order them online
Various collectors have them from time to time, and my wallet is often empty.
Been waiting for this test
I had a Turkish 8mm Mauser when I was a young teenager and shot that old milsurp FMJ ammo in the green bandolier, it would easily breeze thru multiple full size trees and it even shot completely thru a 78ish old car. Straight thru the engine block and out the trunk, no doubt 30-06 is extremely powerful but that 8mm just works lol. Could you imagine having an mg-42 fired at you in the 40's, thankfully we don't have to cuz I for one would not want that to happen lol. Really glad you threw in that 8mm you don't hear much being said about that rifle or round much these days, not everything new is better than old.
well in all seriousness the SMKH load is the cream of the crop. Standard SMK is not quite as effective as the M2AP bullet :D
@@BuffRANGE it's amazing how things change over time lol to bad I didn't order cases and cases of those and the ammo back when it was dirt cheap 🤣 if i would have been older during that time I sure would have lol
@@alphaomegasurvivalsupply6548 Indeed. I wish I was into some of this at a much earlier time..
I've been watching all videos . Straight through BABY!
Thank YOu!
Very amazing results. Would you say with a good quality llla backer it would have stopped the SMKH?
I doubt it.
300 win-chad. I'm using this from now on
Mr. Hoffman, someday I'm gonna send you a plate that could stop that antique tungsten alloy. Fingers crossed!
Also their Mantis plate is impressive in it's own way, could probably stop a steel core magdump like an AR500 plate stops a lead core magdump.
When the plate is curved... shouldn't they clay be shaped to the curviture of the plate, in order to simulate how the curved plate would be against the human body.
Adept is hands down, one of the most underrated armor companies out there. They are constantly innovating and pushing the envelope for personal armor. Oh and that plate is only like 650 usd also.
Aren't they brand new? I haven't seen hardly anything of their plates out in the wild. Just knowledge and technicals on Adepts front. This is literally the only testing I could find on one of their plates (other than their own videos)
@@cc-vg4ed they're not new, but they are really low-key. They haven't really leveraged social media much. They make all their stuff in house in EU, i _think_ around Prague.
@@thuglincoln7699 hmm. It looks as if their webpage was created in Q1 of 2021 so that is fairly new. Their contact page says their address is in Oklahoma, USA?
Also their about us says "Adept is a materials engineering and industrial design firm that focuses on the development of body armor and infantry equipment."
@@cc-vg4ed Yeah they used to be called "Diamond age" and they rebranded to adept a few years back. and yeah they have offices here in TX or OK, but they do most of their business in EU and have manufacturing there because of like ITAR and biz like that
@@thuglincoln7699 They should list their manufacturing location so people can vet it. Hesco, Highcom, RMA, LTC, Tencate all list theirs.
this is very interesting you steped it up as far as the round quality goes.
It cost me some serious $$$, but in the end, I think we set the standard if someone wants something above Level IV :D
Just bought mine because of this video. Adept oughta pay you for this one buff
Supposedly “Buffman” saves you some coin and gives me that kickback :)
@@BuffRANGE I already nabbed em I’m sorry :(
@@blykoger No worries at all :D
Impressive stuff! If you have more ceramic left over, please send it Qwe’s way!
Yes indeed. Mail man lost the first set.
@@BuffRANGE yeah, he told me. Shame about that XSapi…

Sir, you are a natural scientist! Science is a philosophy that works!
Thanks!
I love these tear-downs.
So do I !
Outstanding. Very thorough. You Care about this. You should use that dedication to organize your community. Shits about to get real.
This is like the torque test channel for body armor.
LOL I just love your 200 mag AP rounds, ethey should give the plate a solid test. But I always thought that a .50 BMG loaded with the M2 .30 AP as a sabot in a teflon sleve. Sort of like Remington's "accelerator" rounds. Now that round would give any armor a bad day
15:23 The Plate Look-alike the Necronomicon Book of the dead 😅🤣
Nice 👍
Awesome test, you never disappoint 💪
Masterly job Govenor.
Why thank you !
Damn good plate.
The test results are impressive! I almost bought a set, but then noticed it is actually 1" shorter than RMA 1192 and Hesco 4601 M. Colossus is 9.5 x 11.5. RMA 1192/Hesco 4601 are 9.5 x 12.5. So, I went with RMA 1192 for coverage instead and ended up paying 100$ more than for Colossus with a "poor content creator" discount :( I just wish Adept offered a larger plate.
I would hope they would venture into SAPI sizing at some point as their materials and workmanship are working. You can't go wrong with the 1192's though. I have a video of them if you didn't see it: ua-cam.com/video/PQAddn1bRcQ/v-deo.html
@@BuffRANGE Yep. I made my choice after watching your 1192 test. FYI, I wasn't able to use buffman code for RMA 1192 purchase since plates are currently on sale and they don't allow coupons on top of that.
This is the best one yet
Thank you !
Best plate ever seen on your channel ! Thank you very much!
I would certainly agree. I don't think we've tested a tougher plate in terms of advanced threats.
Great video thanks. We need videos like this if anybody is expected to pay over 600 for a plate...this way we at least know what we get for the 600 price
People pay $1200-1500
Each for some high end plates without ever seeing a demo of them! That’s what I’m here for
@@BuffRANGE I prefer layers of 3a in clothing. Like my bulletproof coat. A plate takes preparation...a coat you wear every day is already on your back.
I would maybe get 2 of these plates to throw into my double tall backpack 🎒 that holds my MK18. Other plates are almost 20lbs ....these plates would only be like 10lbs. Makes a big difference when the bag is loaded up and heavy.
@@mobilegamersunite yep. Hard to argue what you have on your or immediate access to vs something at home.
That’s a bad ass plate
Super cool 😎
I did exercise today sir! Thank you
Good work!
Looks like I found the set of plates to purchase for my Agilite K19 v3.
Hard to say no ..
I'd like to see companies put thin metal inserts into plates, perhaps before the UHMPWE backer, to help contain backface deformation. NIJ standards for deformation are way too lenient methinks.
That’s sometimes called a crack arrestor.
Would be better to be behind the polyethylene.
Yeah you’re gonna be feeling that
Anybody else having an issue accessing the site? I'm super impressed and am considering buying a set.
Did I Crash it?
That uncle rodger clip tho 😭🤣🤣🤣🤣
He sure is funny!
Great video as always!!
I just love it when the 8mm smkh comes out, you got any more rounds for future videos left?
Yes, but am always looking for more. Wish they weren’t as expensive as they have become :(
Only thing I would like to see is them develop some of this new metallic ceramic foam stuff that they are now producing and working with. It both absorbs and breaks up most every penetrating round they throw at it and seems to have huge potential combined with other technology.
That foam would be cool to see mass produced!
@@BuffRANGE it’s not as complicated as u think. Several ways to diy it even. It’s all about getting temp and cooling right. But several methods to produce it. The next is incorporating high entropy alloys into the foam.
@@kevinb.8649 That sounds well outside my wheelhouse of expertise :D
Thanks!
My pleasure!
I can already feel my lungs filling with blood from my shattered ribs 😂🤣
Likely be fine :)

Been waitin on this one!
I was super interested until there was no country of origin or NIJ certification. When that can happen there will be a real winner here.
European manufacturer. I'm sure NIJ certification can be done. I'll leave that up to them.
Great teardown!
Thank you!
Outstanding video man, like always! Hope you have a great Thanksgiving :)
You as well🦃🦃
i am impressed
Impressive
Wow! Great info and testing
Thank you!
It would be so interesting to see how this performs against XM1158. My guess is it would go through because the XM1158 bullet construction is supposed to be some new improved magical tungsten carbide in addition to having exposed tip which supposedly aids tungsten penetration.
If you find some let me know. I was told exposed penetrators are worse for ceramic penetration, but could have sworn I’ve read the reverse
@@BuffRANGE I had AI do some research this is what it told me:
When focusing strictly on ceramic armor penetration capability, research suggests that exposed tungsten penetrators are generally more effective than non-exposed penetrators. Here’s why:
Penetration Mechanism:
Immediate Impact:
Exposed tungsten penetrators have a direct and immediate interaction with the ceramic surface. The high density and hardness of tungsten carbide allow it to initiate shattering of the ceramic layer upon impact. This immediate interaction maximizes the initial penetration effectiveness, creating a more significant breach in the ceramic armor.
Studies indicate that the direct exposure of the tungsten core increases the likelihood of defeating the ceramic layer quickly because there is no intermediary material (like a copper jacket) that needs to be penetrated first (SpringerLink) (Wikipedia) .
Energy Transfer:
Exposed penetrators can transfer kinetic energy more efficiently directly to the ceramic material, enhancing the penetration effect. The absence of a softer metal jacket means that more of the projectile's kinetic energy is focused on the ceramic layer, leading to more effective penetration (Refractory Metals and Alloys) (Wikipedia) .
Comparative Analysis:
Exposed Tungsten Penetrators:
Immediate engagement with the ceramic material.
Higher probability of shattering the ceramic layer upon impact.
More efficient transfer of kinetic energy directly to the armor.
Non-Exposed Tungsten Penetrators (Jacketed):
The initial impact is cushioned by the jacket material, which can slightly reduce the immediate penetration effectiveness.
The tungsten core is protected during flight and initial impact, potentially preserving its integrity for deeper penetration after initial contact.
Despite these benefits, the initial interaction with the ceramic layer is less aggressive compared to exposed penetrators (SpringerLink) (Wikipedia) .
Conclusion:
Based on available research and documented performance characteristics, exposed tungsten penetrators are more effective in terms of purely penetrating ceramic armor. This effectiveness stems from their ability to directly impact and shatter the ceramic material, leading to better penetration outcomes. Therefore, if the primary goal is to maximize ceramic armor penetration capability, exposed tungsten penetrators are the preferred choice.
yeah this plate is fucking nuts good. holy shit
Indeed!
Also its cheaper than i expected. Its still pricey but i expected a singke plate to be 1k or better and they are like 650
Always love your work, Buffman! Keep it up! An impressive plate for sure! I understand why you didn't shoot the SMKH first, but I wonder if a fresh uncompromised plate would have had a chance at stopping it. Unlikely, but it makes me wonder 🤔 maybe if you get another one. Haha
Adept thinks it's likely not possible at 45', but if they want to send a fresh plate, I would be willing to start it at 100 yards and try again :D
@@BuffRANGE Here's hoping! Thanks man! Appreciate you!
I'd love to see how this plate stands up to a full 30 round magazine of 7.62x39mm
What x39 rounds? MSC would likely be fine.
I’m getting these when they come out in SAPI sizes. 😍
I wouldn't hold my breath, with a smaller plate company, it's really not worth their time to make them
That's why I don't consider these designs all that innovative as far as weight goes. Anyone can shave weight off a plate by sacrificing coverage.
@@kenofken9458 they are quite innovative in weight for the threats they stop, at least on the civilian market,
@@qwe304 Level IV is Level IV. It's cool that they're kind of overbuilt and will stop unrated rounds, but that really doesn't tell you much about the survivability of those threats.
Adept is a fine company, and it's cool they're developing these things.
Is it $500 a plate better than an RMA? for most people, that's iffy at best.
@@kenofken9458 stopping the best threats made today, I'd say that's pretty novel, if not necessarily useful
I remember when I could put on shirts that were one size too small.looking good keep up the hard work.
