Threads are messed up…. - Strike Industries Checkmate Compensator

I’ve had to strike industries muzzle devices and both of them have had messed up threads… what I mean by messed up is at the very beginning of the threads they are deformed and really rough. You can feel the roughness when you go to screw the comp on and I’m just not willing to potentially mess up my barrels threads to get either of the comps on.
