@@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'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.
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.
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.
@@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.
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.
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 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.
@@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.
@@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.
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.
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.
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
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.
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.
@@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.
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.
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
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😉.
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
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
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.
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
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!
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
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.
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.
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..
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...
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.
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.
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. @@EC-mc7vg
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.
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.
