The Recoil Technologies Double Crown Comp features a two-chamber design that effectively reduces felt recoil while a set of vertical gas ports keeps your muzzle flat and on target. The aggressively crenelated crown is an effective stand-off defensive device or as support for wire cutting. An effective cross between a compensator and a muzzle brake, the Double Crown is exactly what you need.
