    Thanks.
    The few Colt M4 (registered full auto LE guns) I've worked on have all had H buffers.

    It probably won't, but you'll have to find out for yourself. Tina at S.A.W. was saying that they recommend the H2 for a 14.5" barrel.

    I'd put it in and try it. Buy some UMC or Fed AE and load several mags with just a few rounds to test the bolt lock back a bunch of times. If it'll work fine with either of those two mild loads, you're probably OK.

    this is the same answer i cut and paste for everyone who asks this question.


    the buffer you need depends on YOUR gun.

    depends on a lot of factors. BCG drag, buffer spring rate and age, barrel quality/gas seal, gas port size, FSB fit and gas seal, etc etc...

    any one of those, or a combination of those things may preclude the use of a heavy buffer.

    TO determine the buffer your carbine SHOULD be running, do the following.

    dont clean your carbine for at least 500 rds.
    take one of each weight buffer to the range, carbine, H, H1, H2, H3, 9mm
    Load single rounds of WOLF in mags, and test with at LEAST 20 rounds for each buffer. just one round per mag, testing to see that the carbine locks back after that shot every time.

    Whatever the HEAVIEST buffer is, that will STILL Reliably lock back on an empty mag, in a dirty carbine, shooting underpowered ammo........

    is the buffer you want.

    Also test the rifle with a FULL 30 rd mag to add in the factor of increased top round drag on the carrier.

    a good majority of quality carbines will stop at an H2 buffer. "commercial" type AR's may need a heavier buffer due to large (non spec) gas port size.

    Good point. Testing this on a dirty gun will prevent you from finding out later that X buffer isn't actually working for you when the lube has gone thin.
