    What barrel are you using where you are having this issue?

    Anything heavier than an H3 carbine buffer?

    Also Primary Weapons H4

    EDIT: 1168 beat me to it.

    Also note that heavier buffer mass *can* expand the envelope of operation when paired with a suppressor and correctly sized GP. Thus, reducing the delta in BC speed between suppressed and unsuppressed.

    However, this is high level tuning and it's likely that your gas port is just too big.

    Yeah, exactly; we donít yet know the OPís situation.

    If youíve got a dept gun that you canít choke the gas down on when your silencer is attached, or simply a gun that you shoot both suppressed and unsuppressed, and your can has a bunch of backpressure, you can throw a H4 in it to make it acceptable when your can is on.

    Ideally, you choke the gun down and marry the silencer to it. The bufferís a band-aid, but sometimes thatís what one needs.

    A small number of manufacturers have their gas ports just right. When customers complain their gun won't run they focus on educating them in stead of making the gas ports.
    You won't outvote the corruption.

    I know OP referenced carbine buffers, but A5 buffers and rifle buffers can run heavier. A rifle buffer could be made very heavy with enough tungsten weights.

    I also wanted a heavier buffer and was limited to a AR15 carbine size in my 6.5 CM AR.

    I ended up getting the Odin works heavy adjustable buffer and put x3 Tungsten weights in it. It was more like an H4 in weight iirc.

    Just checked on my kitchen scale:
    PWS H4: 7.0 oz
    A5H4: 7.2 oz
    A5H3: 6.3 oz

    It looks like your scale is off by a couple tenths of an ounce.

    Official weights from PWS and Vltor are as follows:

    PWS H4: 6.8 oz
    A5H0: 3.8 oz
    A5H1: 4.46 oz
    A5H2: 5.33 oz
    A5H3: 6.08 oz
    A5H4: 6.83 oz

    My scale is likely chinese, and only useful for comparison.

    By hand, I cannot tell the difference in weight between the A5H4 and the PWS H4. The mass feels identical.

    Edit: they are also filthy. I doubt that contributes much, but now Iím curious.
