I would absolutely discourage people from using them on operational/defensive guns. Shooting that muzzle device indoors and out of cars SUCKS.
I use it on my primary defensive carbine.

It sucks in vehicles but its not too bad.

I wouldnt agree with 14.5" or longer, the B.C SHINES when its on an SBR or F.A weapon.
