    Brownells sells Chrome Silicone buffer springs that are standard weight. CS springs are supposed to last longer than a normal spring. Some people use a spring that is stiffer than stock, but on my midlength rifle the stiff springs dont cycle low powered ammo like wolf very well.

    Does it matter who makes the buffer?

    H2 buffers are available online in several flavors - made by Colt ($60), made by CMT ($30), made by unknown ($29.95 at Bravo Company), et cetera. How you'd tell them apart, I don't know, but I'm guessing the difference for the Colt is mainly for people who insist on these things? Or has the Colt buffer gone through a rigorous testing process involving being laser-measured, x-rayed, thrown off a cliff, run over by a tank, and jumped up and down on by Privates 1st Class in all weather conditions, and that's why it costs double?

    Bravo Company says theirs is a standard USGI part, implying it's military spec. No maker was specified but they do make their own rifles and everybody who's handled one thinks they're awesome. And here, I doubt Grant would sell the CMT buffers if they were shit... So I'm thinking I'll just save myself $30 and go with one of those...

    with a 10.5 (mk18) setup i found the h2 to cause problems from time to time. IF you are running F/A i would recomend an H3 buffer. i got a AAC (a kinda counter weight thingy) buffer, so far no problems. i half to admit i havent done a beta dump(s) with it yet. (thats one way of telling if it will fubar on you) my rate of fire was off the chart so i went with a reducer..

    i did have some short stroke issues with my factory mp15t with some ammo (i think i put the wrong hammer springs back in. i changed out my springs and to a H buffer for more compression. works like a raped ape now.


    my 2 cents.

    It depends on your barrel and the gas hole size, some are larger than others, also the ammo makes a diffrence too, I would try an H and H2
    and make sure your bolt locks back on the last round.

    MK18 type 1: NSWC assembled carbine with contracted and /or overhauled parts complete with all accessories to current standards at time of build will work with H or H2 and could have shipped with either. Units will balance buffer to ammo requirements:
    H okay with M193/M855. (all ship board MK 18’s should have H buffers as this was the standard at the time of assembly).
    H2 needed for MK 262/ R2LP & will run M193/M855.
    H3 may be needed for an extreme cases or when the gas port is eroded but the barrel still groups.

    I know those aren't your words, but Gas port erosion doesn't change gas flow. The top of the port stays the same diameter as the bore area tear drops out.

    You do realize that this thread is 6 years old right?
