Product Description The Wilson Combat Q-Comp is a hybrid AR-15 muzzle brake/compensator engineered to enhance recoil control during rapid fire without the harsh blast and flash common to many muzzle devices. Tuned to minimize side-blast and concussion, it features a slotted expansion-chamber design with no prongs or tines to snag or break. Built from durable alloy steel with a Black Melonite QPQ coating for excellent corrosion resistance, the Q-Comp installs easily on compatible 1/2x28 threaded barrels using the included crush washer.
