    Yes I have. Would I advise it on a 10.5-11.5? No. It isn't the loudest MB on the market, but it makes some noise.

    Not so bad on 16" guns.

    I shoot 99.9% of the time suppressed and to be honest, if you are going to run a SBR, it is really the only way to fly (for many different reasons).

    I'm always curious about this trade-off:

    A muzzle brake makes a suppressor last longer on a SBR. Conversely, a MB makes you WANT/NEED to run a suppressor more often. However, as your suppressor usage approaches 100%, they weight/cost of a quick detach suppressor makes less sense. You could go with a thread-on suppressor for less money and weight. A Gemtech tundra is only a little more expensive than a KAC Triple Tap.

    Everyone is different. Some folks do not care that their MB or whatever is offensive to others. Some NEVER shoot around other people so it does not matter.

    Any SBR (without a can on it) is OFFENSIVE to me (no matter what type of adaptor is on it). I also shoot around a lot of people and am often times inside closed buildings. The instructors I train with make fun of and or HATE MB's and comps so to run one in a class would open you up to MUCH feedback.

    Other than being able to attach a suppressor close to where the gas block is on shorter barrels is there any other performance/functional difference between the MB556K and the 556K-SB?

    Other than that using the SB, could you attach a suppressor on a 14.5" barrel using a 13" rail?

    As a more general question to anyone where is the follow-up shot advantage of an MB mitigated/lessened by concussion/overpressure?

    I have seen other SF can with similiar round counts where the first baffle is almost gone.



    What does this look like? 2x the hole size? 3x?


    I am getting what looks like pitting around the hole on my blast baffle of my K but the diameter is unchanged.



    Good luck

    Whoops. I was thinking of the "Trek" suppressor. Also when I wrote that above, I neglected to take into account the $200 transfer tax in the price difference. This would make the price difference between a triple tap brake alone and a new Trek more significant.

    No other advantage than allowing you to bring the can closer to the rail.

    Cool...last questions.

    Is the SB long enough to make a 14.5" DD barrel non-SBR legal if rockset?

    Yes, but rocksett is not a legal way to make something 16" overall.
