I have/had several muzzle breaks from Bushmaster that have a set screw so you can line up the gas ports.
On my HK91 clone the set screw messed up the threads on the barrel. Short of messing up my AR barrel, do I just use washer/s to shim it up to get the correct setting on the break? Is there a better way? |
