    I remember reading somewhere that it has to do with the way the weights inside the buffers work. I believe the one slinding weight inside the H buffer works to keep the bolt from bouncing by acting like a secondary hammer strike after the buffer initially pushes the bolt forward. Whereas the 9mm buffer doesn't have sliding weights. I could be remembering wrong or quoting someone that was incorrect.

    That's why HK bolts have tungsten powder ("granulate") in them. You definitely notice a weight that moves back and forth when you shake the H, H2 and H3 buffers.

    Throw in an unshrouded carrier, notched hammer and a gun with bolt bounce and problems can start to add up real fast.
    Is this why you recommended changing the hammer in mine? You told me but I don't remember. AR ran great all day btw. :thumbsup:

    Notched hammers can lead to Carrier Wear, and cycling prolems. It has nothing to do with bolt bounce, but then you have other issues abd bolt bounce its hard to diagnose problems.

    Its best to use a solid setup and then see it any problems rear their head.
