Love their products - Precision Armament M11-SPR Muzzle Brake

I highly recommend PA muzzle breaks. I have one on my bolt action 308 and now one for my AR-15 and they are fantastic. they definitely tame the rifle recoil and their other models have been proved one of the top 3 most effective in reducing recoil. Looks great, fits perfect and functions as desired. The only thing that's a short coming for me on these is that they don't come with crush washers so either be prepared to buy or have your threads times so you won't need a washer...note, the washer is cheaper :).
