    I took the can off a few times during our shoot just to check it out and see if there was any lock up/seize with the mount system. Can comes off fine and the big collar is easy to unscrew when the can is warm/hot.
    Pretty cool review. Thanks. People who own KAC cans really do seem to like them.

    This the MD we’re talking about? I go back and forth on KAC vs Surefire cans almost every day otherwise I would’ve already replaced it with either a WarComp or MAMS.

    When I ran the NF on 1 power and ran some racks the gun didnt budge. It just smoked through them.

    KAC is the answer to the question you’re asking yourself daily. I don’t know your hobby/money situation, but the CQB version of the 762 QDC is great too. KAC makes 5/8x24 and 1/2x28 versions of the short, closed end flash suppressor that serve as excellent hosts. The QDC mounting is excellent. I use that can on several hosts. I greatly prefer it over SF.

    I have 3 gen 1 mams, are these things collectible yet?

    Jack, can you quantify performance improvements gen 2 over gen 1?

    In other words is it worth swapping out the gen 1 to the collectors for current gen 2s?

    The design was changed when we discovered that pushing multiple magazines of full auto with a short barrel would cause the ported area to distort.
    The revision corrected that issue, making the device stronger.
    There is no difference to recoil reduction between the two versions.

    Thank you Jack, not worth the headache then.
