    thanks for the replies.
    Sounds like you might need to check your action spring, provided that lubrication is adequate.

    I am an idiot, but I think "smooth" recoil should not be in the same sentence as reliability in an AR. The stroke is too short for the variance in everything else to be both. Go with the bounce off the extension as added energy to forward stroke and call it a day.

    While overgassed guns are not good, I think you're right. "Gamer-gassed" guns can be bad too, especially when the user doesn't consider WHY they're making the modifications that they make. Add an obnoxious muzzle brake, a lightened hammer spring, and one of those tiny-objective variable optics that can't resolve shit in low lighting conditions, and you've reduced a useful tool into a finicky toy.
    Oh no, not another lube thread! Read this first: Lubrication 101.

    well, the H buffer worked fine... on saturday. on sunday it was giving me 2-4 malf's per magazine.

    I guess midlength just wasn't meant for heavier buffers. I'm going back to the CAR. Thanks for your advice guys.

    It's not that the mid-length won't run with a heavier buffer, it just sounds like for whatever reason, your combination is more reliable with the standard carbine buffer.

    If your BCG & buffer is hitting hard on compression, that's a problem that needs to be addressed with spring rate (or the reciprocating mass needs to be lightened). Adding to the reciprocating mass with the same spring rate usually exacerbates the problem. It takes more energy to move the greater mass but it also takes more energy to stop it.

    If the BCG & buffer is bottoming out too hard, try replacing the spring. Before going with a spring with a heavier than standard rate, make sure the current spring isn't worn or too light

    Any experience with an SR-15?

    I run a H2 buffer,Wolff extra power spring and 2"Battlecomp on LMT 16".Gun runs like butter.

    H2 buffer with Spinco blue spring in my 14.5" Centurion Arms middy (1,500 rounds)-- I also run this set up in my DD 16" carbine (6,600 rounds). Both function flawlessly and smoothly.

    but does it "feel smooth",

    my point is that with the variation of ammo, From Tula to M855, if you have a weapon that can cycle with the low and high end, then you may feel a little more recoil which isn't hardly much on the hot end. If you're got a real soft shooter with hot brass, you are screwed with reliable operation on the not so hot brass. So man up and separate the variables. It's also very hard to have a super fast car that also gets over 40 mpg. Not a perfect world, stroke is partly the culprit.
