    H vs. H2 vs. H3 buffers

    What's the difference other than the weight ofcourse? How do you know which one to use?

    I don't think there is any difference other than weight. As far as deciding which one to use, I would use the heaviest one that allows your rifle to still cycle completely and reliably. I like the heavier weights because it makes the rifle recoil softer and allows easier follow up shots.

    i normally pick the heaviest one that will still cycle WOLF reliably and lock back on the last shot.

    I take 20 mags, and load them all with ONE round. run through that cycle a few times, and you can be reasonably certain that the rifle will function correctly with that particular buffer.

    HOWEVER. keep in mind, that when the rifle gets hot and dirty, you then may start experiencing short strokes with a heavier buffer.

    SO, whatever the heaviest buffer that will reliably lock back on the last round, fully cycle........EVEN when using UNDERPOWERED ammo (wolf) and with a dirty action.


    THAT is the buffer you want. a proper weight buffer will minimize battering of the parts, soften recoil impulse, improve follow up shots, increase dwell (hense increasing accuracy, and minimizing chamber blowback).....etc.

    Good advice here.
    I have 3 SBRs (10", 11.5" and a 12.5") and run H2s with them. I experimented around with different ones and these had be best feel and still worked with weak ammo.

    My Colt with PWS piston kit feels best with a Enidine buffer hydraulic buffer followed closely by a H2 buffer. With a H it feels weird is the only way I can describe it. With and H3 if feels like more linear recoil almost like shooting buckshot through a 20ga, very weird.

    The difference is weight. The result for the shooter is that it affects the feel of the recoil impulse.

    Just after I got my 1st AR together (16" mid-length) I went shooting with a knowledgeable AR guy who brought along a selection of buffers. I tried H, H2, and a 9mm. Allowing for the fact that recoil is subjective, to me, with the 9mm buffer the rifle barely twitched. Conventional wisdom seems to be that you use the heaviest buffer you prefer, which which still cycles Wolf reliably.

    I fired Wolf and Prvi 55gr. with the 9mm buffer and everything seemed in order. I plan to give myself a little margin and use the next step lighter than that, which would be an H2.

    No, next step lighter than the 9mm would be the h3
