M*CARBO Brotherhood

Ar9 muzzle break

I’m building.a 9mm AR and was curious if the mcarbo break would work on my build? I have one on my sub 2k and like it.

you might have to make a spacer depending on the thread length, but as long as the thread pitch is the same size, it shouldn’t be a issue. as long as its a 9mm barrel and threaded for 1/2" X 28 pitch thread. just make sure you dont order the .40 cal one by mistake…

I tend to use jam nuts instead of crush washers now worth a try. Thanks!

Recently found a barrel that’s 1\2 x36 So the mcarbo muzzle break will work with the application. Thanks for the replies and likes!
