Quoted: I'm toying with the idea of replacing the stock brake on my Postie M4 carbine. It has the type with the 3 slots on each side and is slightly larger in diameter than the military style. It's the pin on model and I'd like to replace it and the sight tower to their preban glory.
Has anyone done a side by side comparison sound and performance wise to the A3?
Suggestions or tips on removing the pinned on brake?
Yes, I'm considering sending it to a pro. TIA. |
i don't know what an A3 is, do you mean A2 birdcage? the brake is noticeably louder with more muzzle flash...
there are two spring pins holding the brake in place... drive them out and pull the brake off... there might be some carbon buildup sticking it to the barrel... just twist it a few times and it will pop off...
you will need to send the barrel out to be threaded. use ADCO firearms.
leave the FSB alone, your 16" barrel can't use a standard bayonet anyway. the colt FSB is taper pinned, F marked, and the proper carbine height. save your money.
