Good brake, but - Precision Armament M41 Severe-Duty Muzzle Brake

The only complaint is that it gets loose immediately after one shot. I'm shooting 300WM and 7mm usually and without blue locktite or a crush washer of some kind, it will immediately get loose. I love the fact that you don't need to index it and it looks great. I shot a 7PRC with and without this and there is a very noticeable difference. In my case I also shoot suppressed when possible (depends on state) and thus the thing getting loose when suppressors are not allowed gets annoying...and I don't want to have to fight to get it off every time. Would love to see some kind of clever mechanical solution for this (maybe a small set screw somewhere?). Other than that, love it, have three.
