I purchased a threaded muzzle break (ordered on 9/16) with a crush washer. First,
the speed of processing and shipping were better than Amazon and the
like. My daughter will be using this rifle for deer hunting.
I made sure to have her and I shoot the .243 before and after the
installation…she was really impressed (as am I) with the reduction
in recoil, so if I ever have any need of another brake or have an
opportunity to refer business, Kahntrol will be at the top of my
list.
