    It's running fine on a stock spring and C buffer, yes?
    Rog. Refer to title though. This is a competition gun.

    Are you outrunning the gun with the original pars?

    This seems like something that wasn't an issue until you decided it was an issue, and now you have the exact result of fiddle-****ing that I and others use as a reason not to fiddle-**** with things that work.

    So what if it was slamming into the back of the receiver extension?

    All three of my BCM middies run fine with rifle buffers.

    thanks for the replies.
    That is a problem with the ST-T2 buffer. It is a neat idea until you realize that the weight inside can be floating in air and not "engaged" so to speak and effectively have too little active mass to do what the buffer is supposed to do. You fix this by using the right parts, not some buffer with two dicks engraved on the front of it.

    Not defending Spikes parts.... but just out of curiosity, how would you rate your own understanding of physics?

    Sufficient.

    If you have found an error in my explanation please let me know. It is based on a Spikes ST-T2 buffer from 2010, around May, and some high-speed video and actually having many other buffers in hand.

    So, if you're in a free-falling elevator and jump up in the air right before it hits the ground, will you be injured?

    Did I say that?

    If I were to jump just before impact the impulse of the impact would be altered as there is less mass initially slamming on the ground.

    Take a water bottle that is half full, or half empty. Turn it horizontal and shake it slowly back and forth. Does it feel consistent or does the water moving around inside have an impact on the amount of force needed to continue the cycle?
