Great for light weight builds - Faxon Firearms .620in Streamline 3 Port Muzzle Brake, Steel, QPQ Nitride

This is an awesome brake to use if you are trying to build out an extremely light weight AR-15 pistol,carbine,rifle etc. it works like a charm on my Voodoo innovations 14.5 inch barrel!! The fit and finish are good and it allows full removal of your gas block and/or barrel nut with out removing the brake first..the device is 0.620 and on a faxon or voodoo barrel that leaves you 0.005 of an inch leeway....so IDK how well it would allow disassembly once pinned and welded,i built a pistol so no worries...just something to consider on a carbine build.
