Product Spotlight: Bravo Company Mk 2 Recoil Mitigation System

- čas přidán 8. 07. 2024
- Some folks are more sensitive to recoil than others, but as a general rule, it's a Good Thing when you can reduce a rifle's felt recoil. That's exactly what Bravo Company Mk 2 Recoil Mitigation System does for the AR-15. Brownells Gun Tech™ Caleb Savant is here to explain how it works. Consisting of a recoil buffer, buffer spring, receiver extension (aka, "buffer tube"), castle nut, and end plate with a handy QD sling swivel socket, the RMS is Bravo Company's take on the A5 buffer system. Both recoil systems occupy the middle ground between rifle and carbine systems. So the Bravo RMS / A5 buffers are longer than carbine buffers but decidedly shorter than rifle buffers. The recoil springs are stronger, too. The buffer tube is longer to accommodate the longer buffer, but the tube accepts any collapsible (adjustable) stock that fits a standard mil-spec (1.146" O.D.) carbine buffer tube.
BENEFIT #1: The big benefit of BCM's Recoil Mitigation System is making your rifle a LOT smoother shooting because the extra length spreads out the recoil impulse. "But wait," you ask, "how bad is the recoil on a .223 rifle?" Well, there is still some recoil, and mitigating it enables you to make faster follow-up shots. You can watch the bullet hit (or miss!) the target through your optic. That's pretty important when you're in a timed competition, yes?
BENEFIT #2: The RMS also makes your rifle more RELIABLE, regardless of its gas system length. The recoil spring's extra oomph coupled with the heavier buffer means more weight driving the carrier forward to ensure that next round gets chambered. You enjoy awesomely reliable feeding, while the extra weight and receiver extension length mean gentler felt recoil.

This is the new hotness, I hope it becomes standard.
It's been around for over a decade and it really hasn't taken over the market.
The almost 12 year old new hotness that you should absolutely buy from bcm because, 1. it's more expensive
2. Daddy vickers is going through a tough time right now.
And 3. who can spell Vltor into Google anyways? Oh, and because this gumby haired Pog says so. Silicone chrome™®©
@@anthonyaragon6639 Don't get me wrong, I've used A5 in a couple builds over the years and it's definitely smooth but it's an AR-15. I've never had a problem with recoil in an AR15.
@@charmingmander331but as compared to a carbine length buffer system its not going to beat on the rifle as bad right? Especially if you're using a shorter barrel?
I hope your hair-do doesn't become 'standard'. "This is the new hotness"...
Huh... GGGAAAAAAAAAAYYYYYYEEEEEEEEE!!!!! 🌈🌈🌈🌈🌈🌈🌈
I'll say this loudly for those in the back or hard of hearing: No you cannot achieve the advantages of A5 by simply using a heavier carbine buffer. The rifle length spring makes a difference.
So you're saying I can just use a heavier buffer.
@timrobinson6573 H9 is the best weight. It's made of Uranium.
Does the same thing as a flat wire spring. The spring travels a smaller portion of its total compressible length. Spring doesn’t bottom out and it’s spring force is more constant.
All good to know info
Guess you never heard of springco springs.
A former neighbor of mine bought a DPMS LR-308 at an estate sale and asked me to come shooting with him. That thing kicked like a mule and wasn't reliable at all. I felt bad for him, because he was so excited for his new purchase and all I could really do was recommend an A5 buffer tube and an AR15-length H3 buffer. That combo made his gun cycle correctly and it cut the recoil dramatically. I know that's not really how the A5 is normally used, but I was really impressed with how adding a heavier buffer smoothed out recoil for his rifle.
Looks like Mr Rogers but is packing an AT4 in his safe. “Walk softly, but carry a big stick.”
I run BCM, VLTOR, and SOLGW on most of my builds. Dead on reliable and smooth shooting.
Do you notice any difference between BCM and Vltor?
@@khangngo753 Not really, the impulse is very similar and when I go shopping at my lgs they have both sets next to each other for A5 MK2; interchangeable far as I know. Opted for the heavier buffer weight MK2H2 for MK18 clone testing this weekend. A5H1 in the SOLGW 300, and 5.56 various build doesn't seem to have an issue.
A5 is great for silencer use. The "cost" is only about 3/4" longer tube than the carbine system and everything else you get is advantages.
Yup, for young women learning to shoot it will probably help alot (what other advantages though?)
Thanks. I want my rifle short though.
@@abstractapproach634not sure if this will mean anything to your underdeveloped understanding of the rifle system, but weapon enhancements that augment the reliability and efficiency of the AR-15 weapon system are truly upgrades to said system. I get it, you think having a more violently recoiling system is some sort of Hallmark to your fragile sense of masculinity and that is important to you, so I don't want to take that from you. Happy New Year lil guy.
Nice work as always, thanks.
I used the green sprinco rifle length in my a5 systems, if you partner it with LMT enhanced BCG or the CMC enhanced with the extra gas port, any over gassed SBR can become a pleasure to shoot... love it, also use a custom buffer, everyone loves shooting it compared to the standard.
I have the LMT paired with Hodge and solgw barrels and a5 everything and there really isn't anything better at that point. Also have a sonics dedicated suppressed 11.5 that's a sewing machine on auto.
@@kristjonpedersen9342 Nice, I have the 12.5 Hodge barrel.. using the LMT enhanced w/ Armament LARB mod3.
Also Geissele 416RS 10.3" w/ CMC enhanced as a 2nd upper.. both feel silky smooth.
Have you tried a standard A5H2 buffer vs the Armament LARB mod3?
@@Rossski I had the KAK whatever that was it was black, gave it away.. perhaps its the hard rubber pointed end of the mod3 that makes the difference, couldn't say between 250rd on each.. I bought 3 of the mod3 LARB's and gave everything else away, I suppose that speaks for itself.
@@Rossski Also to note that I forgot, I added the leitner-wise g2 buffer retainer on all of my lowers w/ the A5 tubes, not a fan of the standard pin point, I've broken 2 with the MOD3's so far, no failures with the g2, wouldnt expect it either.
I’ve been using the VLTOR A5 Buffer System for years on my 13.9” and I love it. I swapped out the A5 spring and use a JP Enterprises Rifle Length Tuned and Polished Buffer Spring which makes it much quieter and smoother. It’s also less expensive than the JP Silent Captured Spring.
Is the JP rifle spring stronger than the standard A5 spring?
Standard is really weak imo, gonna try the Sprinco green.
This might be the ultimate combo. I haven’t used A5 buffer system (I want to) but I use the JP tuned and polished springs in every build. Best spring on the market.
I've got a few of the a5 systems from various companies, I really like them because it seems to barely puke out the brass and it's so consistent, but I can also throw that same rifle in a deep freezer and it works fine. No where near as violent.
I have it on my firearm and I absolutely love it
BCM Mk2/A5 Mafia!!! 🙌🔥
I figured out my own system. I used an old AR-10 buffer extension old A2 rifle spring and just ordered a Viltor buffer. Works like a champ for me
Is the traditional rifle spring longer than the A5 spring? And couldn’t you just use a heavier rifle buffer and it would comparable to an A5 buffer?
because someone wanted to run a TDP carbine buffer in a large frame AR, we have the A5 length receiver extension. someone looked at that and said, why not add some more mass and spring to a small frame AR, and we got the A5 system. 5.3 oz just happens to be the TDP buffer weight for a rifle buffer.
Full auto web a lower rate of fire is another reason to get one. Heavier buffers reduce malfunctions and increase control.
About to try mine out
And both the Vltor and the Bravo use a standard rifle-length recoil spring with their buffers. I switched my buffer tubes out for A5's years ago, what I noticed was the carbine uppers cycled more reliably when dirty and I didn't break any more bolt lugs since it reduced the carrier speed over the standard carbine setup with a 3 oz buffer.
So would the Bravo Mk2 buffer kit be good for an 18 inch barrel with rifle length gas system?
I used a bcm mk2 buffer tube a springco green spring and a voltor A5H2 buffer on my bcm 13.9
My next build will be a 16" mid length gas system with one of these 2 buffers.
Love the system. Big fan of both BCM and SOLGW. As you mentioned Mike's video on the A5 system he says the reason why you would want to have the weights in the buffer shake/rattle is so that when the bolt closes the fwd mass of the weights slaps the "bouncing bolt" back into battery. However this is one difference I've noticed about the BCM buffers...they don't rattle. Idk what or which is better but that's a difference I have seen.
Mike's A5 video has him glowing about the fact that the buffer weights don't bounce. I just came from there.
I haven't seen it for a while for some reason but 10 years ago when I started using the a5 system there was a fantastic super slow speed video that showed a carbine and an a5 rifle simultaneously and you could totally see the difference in bounce. The carbine was crazy sloppy compared to the a5 which just went into battery and stopped.
A carbine buffer system does fine and has worked well for many many years but it's kinda like the difference between an a2 forearm vs a free float rail; it just helps the rifle act more natural and makes it objectively more solid, reliable, repeatable, and consistent
@@BarnDoor-won5ve I remember that video.
Add a geissele super 42 rifle length spring and a forward controls design a5 castle nut, and you're good to go.
Yes, add a shitty geissele spring and an overpriced castle nut
My second favorite buffer setup, after the JP Silent Captured Spring System. And you can run the JP SCSS in an A5 tube if you want.
Is there any benefits to this
@@dogevanzandt2889Smoother recoil impulse, less "sproing!" noise, more length of pull adjustment and more refined feel when working the charging handle (no functional gain, but it feels better, and feeling good is almost as important as looking good!).
@@Croak1 I was specifically talking about running the SCS in the longer tube. I am very familiar with the SCS but my understanding is that it runs the same in a carbine length or rifle length system.
@@dogevanzandt2889Just the ability to run it in a longer tube (with spacer insert) if you want the greater LoP or already have an A5 length tube and want to upgrade.
@@Croak1 I figured there was no performance advantage. I run my stock in tight so this doesn't affect me. Happy New Year to you.
I know someone that used an A5 system on their AR pistol for that little extra length of pull.
I've been using one of these in my AR-15 since I built it three years ago. Funnily enough though, my BCM MK2 kit actually came with a VLTOR buffer, not a BCM marked one.
Nobody talking about the rocket launcher in the safe😂
Shouldn't have to, let's normalize it!
The reliability enhancement is dependent on the gas pushing it back though, had some issues with a rifle length gas system and rifle length buffer system, didn't change anything, but found it doesn't like the lower pressure .223
So which is better the BCM mk2 recoil system 9r a Geissele supper 42 spring & buffer for a standard 14.6-16" barrels with mid length gas system???
Unrelated question- graphite dry flim spray, has it any use in the AR15 Platform? Buffer, BCG, so on?
What's the difference between the different models you can select on the product page?
This seems like it would help a lot with shorter suppressed setups. Would that be the case?
Anybody have comparisons between this and utilizing the Geissele Super 42 Braided spring and H3 combo?
ADM makes an a5 length tube too. I'm running it with my uic lower with a5h3 vltor and sprinco green
Good call, didn’t know ADM made buffer tubes for the A5. I have their 13.9” but A5 with the H2 and Sprinco green was too much for it. I put the BCM A5 spring with the H3 and it need More!! I have the Sprinco H0 and the BCM H1 to try with the Sprinco green to try next. If I’m happy with it I will get the ADM A5 Tube to keep it as ADM as possible😉.
@@derek3154 nice, yeah I'm a big fan of ADM. All the companies you mentioned are solid too
Which RMS would you use for an 11.5’ AR pistol upper?
I see the products on the website listed as T1, T2 etc but don’t know which one. Help me out here please.
Great video..
I would like to see a video on the plus' and minus' of Chrome lined barrels versus the coatings that harden the barrel. I think Chrome is still better for feeding and heat resistance, yet most companies don't do it any longer.. Also, is stainless as good as chrome lined, etc..
Thanks
Tim
Chrome lining does harden the barrel, and it's still standard on almost any duty grade rifle.
@@KeepTheGates Yeah, I think I'll buy a colt because of the chrome lining or an FN.. Thanks so much for the reply!
So this would make my 11.5 feel more like my 20" A2?
I have been retired for a while now. I am not familiar with the A5. The m4 was the current issue when I retired
So would this work to reduce recoil in my carbine gas system Colt M4? I already use a heavier wolf spring with H2 buffer.
Yes it would, as long as you plan on using the whole system instead of trying to simply jam the buffer in there to try and make it work
Will it soften the recoil of 9mm blow-back operated ARs?
HOW WOULD YOU COMPARE THIS TO THE SUPER 42?
Bcm. The classic company with never anything in stock.
Can I use a Geissle Super 42 Rifle length spring in this MK2 tube? Or is there another option?
Yes, you can use it. I use it with my A5.
Would this help with my overgassed DDM4V7 11.5? With an H3 buffer it ejects perfect with 55gr but when I use my self defense ammo 77gr 5.56 it’s wayy overgassed.
Yes it will
is this good for 300 blackout as well?
Still trying to figure out if either the T0, T1 or T2 buffer weight with the Bravo MK 2 recoil mitigation system would work best for a AR-15 platform chambered in 7.62 x 39 carbine length gas tube, mil-spec 0.750 GAS BLOCK, 0.093 gas hole, with a 16 inch barrel. I would think the T1 would work perfect but I still have not seen any info or any trials for my build.
Even with those details, that's not enough info to know what weight to go with. The gas port size makes a huge difference there.
0.093 gas port and 0.750 gas block@@KeepTheGates
I run a standard carbine tube, spring and standard weight buffer in most of my hog guns, 5.56, 7.62x39, 300 Ham'r, 350 Legend and 450 Bushmaster, rifles and pistols, and all run just fine. I used an H2 buffer and a flat wire spring in my 10.5" 7.62x39 pistol, not sure it really makes any difference, but it is just as reliable as all the other guns I've built.
That is what my friends use is an H2(4.6 ounce) buffer in their carbine length 556 and 7.62 AR platforms. The Bravo MK2 buffer system uses a slightly longer buffer tube and an A2 M-16 spring which is longer and tighter to compress than the standard carbine spring , The T2 buffer weight is 5.6 ounces and the T2 buffer weight length is in-between a standard carbine and a rifle length buffer. The idea of the Bravo system is to reduce recoil due to the slight BCG lag between going into battery and the next round firing. If I get the T2 system and see it under gassed I will replace a steel weight with a aluminum buffer weight. I really don't want to be over gassed as it breaks extractors in AR platforms for 7.62 x 39 using steel cased ammo. @@ErickaC-mc7vg
Which buffer weight would you recommend for a mid length gas system?
There isn't a "one size" buffer for mid length. Barrel length matters, as does the gas port size, how often the weapon is cleaned, how efficient the BCG is, and your choice of ammo.
@@KeepTheGatesok that all makes sense. I just wondered if their was a a standard baseline that should be good. I have standard carbon buffers in all my set ups with carbon& middlenth gas systems. Everything runs good. Just wanted to see if I an make one run better...
@@maxcole3930 It seems that sons of liberty uses the H2 weight as standard in their A5 system so I expect that would be pretty reliable for you.
Is it smoother than a rifle length buffer system?
I mean it makes sense, the AR started as a rifle length gas with rifle length stock and then carbine gas and stock came out and then mid length gas came out but no mid length stock and buffer…til now
How dose this compare to the super 42 buffer system
Super 42 is for carbine length systems. Basically a replacement. They are awesome and make solid difference. I run them in a few of my set ups, and also run the BCM system in 2 weapons. These are cheaper than VLTOR, and work fine for my needs.
He didn’t specify, is this BCM MK2 T1 or T2? If I’m not mistaken, they both say it’s an “M16A4” system. If I’m going for the VLTOR A5 equivalent, would this be their version? The T1 is a 4.6oz buffer and the T2 is a 5.6oz buffer I believe.
i'm trying to figure out the same thing. i have a Mk2 BFH ELW 16" that plan on running both supressed and unsupressed. Not sure if i should go with the T1 or T2, whats a better midle ground while hooting both with or without suppression
Would this system work with a 10.5" upper?
So it will run reliably with a mid length gas system correct
97% of the time, yes.
Correct, yes.
@@brownells which buffer weight would you recommend?? Mod 0-1-2???
This is a very stupid question... But.... How hard would it be to replace my current milspec buffer system with a longer one like in the video? Is it a tough swap or can anyone do it?
.... My biggest problem is that I don't have any kind of traditional vice to hold anything still.
It is an easy job with the right tools. I WOULD NOT recommend attempting it without an armorer's wrench and a vise. You will need to break the staking (assuming it is staked) to remove your existing receiver extension (aka buffer tube) and torque the castle nut to iirc 38-42 ft/lbs when you install the new receiver extension. Not going to say it is impossible but it should really be done with the proper tools.
@@Deltaworks23 That's my biggest problem.... I have all the right tools but I still don't have a vise. I've been looking for an adequate bench that I could bolt a vise on but the hunt for a decent bench has been hell. For anything new you'll pay an arm and a leg.... I've found a few great deals on used benches but they're always far away and I'm without a truck bed.
@@TerminalM193did all mine without an appropriate vice, wasn't a problem
What’s the difference between the BCM MK2 T0, T1 and T2?
Buffer weight, higher number = heavier buffer.
@@bradtidball5206
Ah, makes sense. Thanks. 🤙
weight of the buffer.
So which one is the best?
Would that work with fcd buffer tube ?
The A5 Length (RE5F), yes.
Why has no one made a rifle length buffer tube capable of accepting an adjustable stock?
Because on it's shortest setting, the length of pull would be at most peoples maximum LOP.
I found the A5 systems increased perceived recoil, but are a plus advantage with suppressed rifles..Suppressed rifles will decrease the rifles life by half and any advantage such as the A5 systems to be a benefit..
How did you have an increase in recoil? Every machine gun that I've used an a5 on, paired with an appropriate gas port ran amazing.
Increase? I've never heard that. What weight buffer are you using?
3.8 oz. for the A5.. 2.1oz for JP SCS@@mrsickwick
Increased recoil? What are you on about? It does no such thing.
Yes it did, I didn't remove it because it was softer shooting lol..I'll take that pepsi challenge any day.. @@InvidiousIgnoramus
No need for this if you’re already running a braided wire buffer spring with an h2 or heavier buffer. Also captured buffer systems crush recoil as well without the added length.
There are still benefits over a standard carbine system. It's not just about recoil.
Got an AT4 in the safe huh?
Me with heavy rifle and gamer brake threaded on: "what recoil?"
I was wondering what AR-15 has problem level recoil.
Is that a L.A.W.S in your safe?
Is there a reason we arent' all using captured springs in 2024? Asking for a friend.
I give up! I am liquidating my assets, and giving up on shooting sports all together!! I am tired of being depressed over not being able to afford parts, upgrades, accessories & ammo, etc., there is no such counity to help build reliable platforms without having to pay top dollar for it. Thanks Caleb & Brownells for all that you have shown and taught me over the previous, years I've learned allot. It's just to bad that knowledge will goto waist!
Maybe learn to spell and you can get a job that pays above minimum wage you dumbfuck boomer.
That's silly.
@@KeepTheGates so are many of the products in new product videos. Silly products to solve imaginary problems.
Great for over gassed rifles!
A5 is definitely great at making carbine gas ARs shoot smoother. I think this video was kind of a waste of time and should’ve just been a TLDR that BCM MK2 = VLTOR A5
so waht are the advantages?
Softer shooter. Supposedly, more reliable lock up. And since it's a slightly longer buffer tube, a seven position slot. At least VLTOR buffer tube has seven stock positions. * corrected - six position to seven.
@@nushinebob because of the increased length, there are A5 buffer tubes that are able to get as many as 9 positions. I'm thinking about picking one of those up and putting a stock stop in so I can quickly pull it back to my preferred LoP.
Less felt recoil, more mass driving the bolt home.
Wont build without enhanced buffer tube with tabs for pin and a flat wire spring. No twang and faster locking.
Add a Geissele spring and I'm in..
It uses a standard rifle length spring, so you could mix and match.
@@brownells Yeah, but the Geissele spring requires a slightly smaller diameter buffer and as far as I know, Geissele doesn't make an A5 buffer.
@@fubar1217 the rifle length geissele spring doesn't require a different size buffer only the carbine length spring does. SKU: 04-308-F
@@brossovitch I stand corrected. Just checked in my "Mock"12 which has the Geissele spring. Looks like I'll be building my own kit using the Geissele spring.
@@fubar1217 i thought the same until i read the description last year. Pretty cool how that works out
I got BCM before the mk2, but it's OK, 5.56 doesn't have recoil.
I'll stick with my JP silent captured spring.
This is good but we all know the geissele buffer system is op
Good, but not as good as the A5 system.
I call placebo affect!
Physics would disagree.
Gee, why would I possibly want a soft shooting rifle to be even more softer to get every cheating advantage I can for reliability, accuracy, and reduced bolt bounce ensuring I have a freight train driving that bolt into battery to all but 100% guarantee a solid lock up seeing how the ar15 functions with a closed bolt system?
I'll never understand why there's people who think just because the 5.56 is soft shooting that it shouldn't be even more so😂
No brainer?
RIP hairline
Gosh. So meh lately.
Recoil from an AR15? If you need this, you shouldn't be near guns.
It's more about faster and more accurate follow-up shots and staying on target.
@@brownells Thanks for the reply. Guess I'd have to try it and see for myself. How would this work with a 11.5" setup?
Because... 5.56 recoil is so horrendous.
Or something.
I HATE it when people say this… 5.56 recoil is not bad… but there’s no reason to not make it less… if not just for the cool factor of having a full power rifle round shooting like your Ruger 10/22.
Yeah….who cares about a flatter shooting more consistently cycling rifle?
@@samuelyoung4646 223 and 556 are not full power rifle rounds they are intermediary cartridges full power rifle rounds are things like 308/7.62x51(or 54r) and 30.06 and what not
Not to mention - just build your rifle right in the first place.
Or... tune it properly rather than the horrendously over-gassed crap you get when you buy a complete rifle off the shelf.
@@cleetismcdougall5425show me how that will make a rifle shoot flatter.
A5 is a gimmick imo. If you want more reciprocating mass just get an H2/3 buffer, if you want more spring pressure upgrade the spring, if you want softer cycling tune your gas. If you need more than 5.4oz buffer weight then you’re probably just compensating for over gassing
Everyone always overlooks the internal bias spring of the A5 buffer, which is where half the benefit comes from.
Naah, longer spring is a big part of it
Spoken like someone who doesn't understand scale length and tension.
so they copied/stole it. lots of american knockoffs.
Incorrect.
Hope your gun is overgassed. Dropping this into a system that is pretuned, is gonna produce reliability issues
Assuming you have the same or less weight in the buffer, how would that cause reliability issues?
I ain't gay but GOT DAMN bro that hair is banging! Side part gang! 😂
