AR-15 compensators and muzzle devices control muzzle rise and shot-to-shot recovery in 3-Gun and USPSA Multigun rifle stages. Competitors running fast splits at close range and fast transitions between targets rely on ported brakes and comps tuned to push the muzzle down and cut felt recoil, letting the optic return to the target. Offerings span multi-port and linear designs with direct-thread and timing-nut mounting, on common 1/2x28 and 5/8x24 barrel threads. Fast same-day shipping on most orders at Shooters Connection.
