TacFire Spiral Fluted Muzzle Brake Features The TacFire Spiral Fluted Muzzle Brake is built from all-steel construction with a heat-treated erosion-resistant black oxide finish designed to withstand repeated high-heat firing cycles. Its spiral fluted exterior isn t just styling the cuts help shed weight at the muzzle while still giving the device the mass needed to redirect propellant gases effectively. Chambered for 5.56x45mm NATO and threaded 1/2x28 it bolts directly onto standard AR-15 pattern barrels without modification. The device s porting is engineered to counter muzzle rise and reduce felt recoil helping shooters stay on target through faster strings of fire. At 2.6 inches overall length and 1.12 inches in diameter the brake adds minimal length to a barrel while still delivering a meaningful reduction in recoil impulse. It weighs only 6 oz so the added muzzle device does not meaningfully shift the rifle s balance point forward. A crush washer ships with the brake to ensure correct timing and a secure properly indexed installation on the barrel s threads. Shooters running 5.56 AR-15 builds for competition range use or home defense will appreciate the combination of recoil control and durable USA-style steel construction this brake offers.
