Gunsmithing AR-15 Rifle Buffer

[splean]

I am in the process of upgrading my AR-15 rifle. It has a 20" barrel and I tend to fire heavier rounds (69-77gr).I was replacing the buffer spring when I began to wonder about the buffer itself. A little on-line research came up with all sorts of buffers for carbines. I was wondering if there was such variety for rifle buffers. Is there a "better" rifle buffer? Any help is appreciated, thanks.

Re: AR-15 Rifle Buffer

I have owned a few ARs and shot many. I am not a big fan on upgrading parts on an AR that I dont belive improve accuracy. I say go with something stock and save your money for something more important.

Re: AR-15 Rifle Buffer

Gernerally buffers act as one of two things "to soften felt recoil" and "prevent action ware". On allot of guns felt recoil can be reduced by several means other than a buffer i.e. shortening barrel, adding a muzzle brake, dif loads, etc. You are talking about a 20" AR shooting a 69-77gr bullet. This leads me to believe you are shooting longer ranges and not a "standup run around cqb game". Honestly in an AR, as long as you have high quality parts, a match barrel, and good ammo, the last thing I would worry about is a buffer. If you find it hard to get back on target for follow on shots, I recomend a surefire brake. If you are deadset on a buffer look at hydraulic ones.

I run an enidine buffer in a few of my ars and I like them. The rifle ones seem to do a better job at softening the felt recoil than the carbine ones.

20" with a rifle length gas system-use what was designed for it, a stock rifle buffer and spring.

H buffers and such came out as a fix to shortening the gas system to extend dwell time.

Re: AR-15 Rifle Buffer

I agree with all of the above. The heavy carbine buffers are intended for full auto short-barrel carbines, which are grossly over-gassed. They do very little for a semiautomatic carbine. If you want to do something that will improve your shooting, install a good aftermarket trigger in your rifle.

Exactly this.Buffer weight has nothing to do bullet weight.It's about GAS SYSTEM.Only thing the buffer/spring/bcg feels is gas pressure which is mostly affected by where the port is and how big the hole is.

Re: AR-15 Rifle Buffer

I would stick with a stock buffer. As long as you're not customizing a 20" AR you will have no problems.
