So I’m thinking of smoothing the 11.5 recoil out and there are tons of options out there but I wanted to ask opinions. The list is short but big players
I figured someone here has atleast played with most or some of these. I’ve had an A5 and I like it but just wondering if the other offerings are worth the coin
What buffer and spring are you running in it now?
I have an A5 on one lower but the lower that’s getting NFAd is a stock KAC lower. Not sure if I wanna move stuff around or what
A properly gassed 11.5 CAR runs pretty well.
Sounds like your barrel may be over gassed.
Heavier buffers are not the best way to compensate for over gassing; correcting the gas drive is the best way.
We have several options for correcting gas drive.
I mean it’s a KAC 11.5 doesn’t feel over gassed, I just wouldn’t mind smoothing it out more if it can be done
Howdy, this is just my 1/2 cents worth and a sample of two. I have 2 11.5in sbr’s. They are both Noveske chainsaw uppers and lowers. The fcg/lpk for both came from white oak armament. Both barrels are Daniel Defense circa 2012 with gas ports measuring .076 both have AAC blackout flash hiders and this is where they diverge. One has a std BCM re running their std carbine spring and an H2 buffer, the other sbr is running the Vltor A5 with their std spring and the 5.3oz buffer. It runs much smoother than the std carbine re. My sons and everyone else who has fired these two sbrs make the same observation that the Vltor re is much smoother. YMMV but I hope this helps.
For several years, I’ve been very pleased using a VLTOR A5, and a BattleComp compensator on two different 11.5 rifles.
My 11.5 was nice with the A5 and AH4
Yeah I’m leaning towards just staying with the A5. When I had my 416 it smoothed that beast out tremendously
I have a couple of 11.5" uppers, both suppressed. Both are smoother with the A5 RE, A5H2 buffer and Sprinco green spring than with an H2. In fact, all my uppers are smoother with the A5 setup. But more important than the choice between an H2 or A5H2 buffer, is getting the gas drive right. If an upper is over gassed, recoil is going to be harsh no matter what buffer & spring is used.
Yeah seems like the genral vote is A5. I think I’ll stay there. Seems like a better roll of the dice to be honest
I have the Geissele Super 42 in my 11.5" BCM AR pistol. Not a lot of rounds through it (under 500) but it works fine with no problems. I had a few ejection problems early on but that was gone around 50 rounds or so.
At the advice of Mr. Larson, I am running an LMT enhanced bolt carrier with BCM bolt and parts, green Sprinco spring, A5 buffer tube with A5-2 buffer with a BCM 12.5" upper. I have only shot it with M855, XM197, Fed Gold Medal Match 77gr and Fed AE 62gr & 55gr. So far it has eaten everything without a hiccup and shoots pretty dang smooth.
I’ll be bringing one of my SBR’s with me since the new 5320.20 approval times are taking less than 14 days.
Op, by “smoothing out” do you mean shoot flatter? I’ve got a 12.5” and 10.5” and both run smooth with green Sprinco springs and H2 weights. Action is reliable in both. I’d direct smoothing to the exit point. What muzzle device are you using? I find a good break to have more affect on flatter shooting than slowing my action. Another area for recoil management is weight. I prefer light quad rails over slim, ultra light tubular rails. For me, the few extra ounces yield flatter shots and quicker follow ups. What’s the rest of your build?
I took him to mean, less felt recoil/quicker return to target.
“Smoothing out” appears to be M4c code for reducing recoil. I was reading an older thread on here yesterday about a buffer designed to reduce recoil. Everyone was jumping on the don’t be such a sissy bandwagon. Because the OP used the word recoil. There were even posters stating that the rifle has none.
But if you say “smoother”, the same people come out of the woodwork with compensators, gas port dimensions, A5 buffers, PMC Bronze, and rainbow colored action springs.
You are not reducing recoil, you are smoothing the curve so it has a lower peak.
Some people call it ‘felt recoil’, but Its best to avoid feelings and quantify it.
A buffer cannot reduce recoil unless it adds mass to the rifle. However, it can soften recoil. It can make the recoil feel smoother. Softening and smoothing recoil helps the shooter control recoil better.
