Fitment issues and fixes - Precision Armament M11 Severe-Duty Muzzle Brake

Any good builder or man that works on his own rifles knows that sometimes things don't work out as usual. Which brings me to the fitment issue. Muzzle brake shims are available at a very low cost. Almost pocket change. With a food shim set clocking it properly shouldn't be an issue at all. Shims are a AR owners best friend. They can be used to take out slop in the front pivot pin, trigger fit, also bolt catch pin so there is little play or movement with a BAD lever. Please consider getting a good assortment of shims to make sure you can eliminate many problems that can arise when modifying your AR platform.
