SureFire ProComp Muzzle Brake

There are a lot of muzzle brakes out there for the M-4 / AR-15 type rifles.  Most do a pretty decent job all said.  But I have recently been pleased with the performance of the ProComp by SureFire.  It utilizes the same design elements of their proven SOCOM Muzzle Brake.
