USED Spikes Tactical ST Dynacomp Extreme 5.56mm 1/2x28 TPI Black Nitride

USED Spikes Tactical ST Dynacomp Extreme 5.56mm 1/2x28 TPI Black Nitride. The ports on these AR15 Muzzle Brakes & Compensators by Spike's Tactical are ball dimples for smooth expansion of gases and rapid heat dissipation and the front of the device is 0.25in thick to better handle the abuse of full auto fire. The direction of the blast on the Dynacomp is balanced along vertical (upward) and perpendicular planes of the muzzle to lower muzzle rise in order for you to have a steadier shot. Equipping the Spikes Tactical Dynacomp Muzzle Brake will help balance the direction of the muzzle blast along those same planes lowering muzzle rise and providing a steadier shot.
