The Spike's Tactical Dynacomp is designed to reduce recoil impulse and muzzle climb to provide faster follow up shots. The Dynacomp accomplishes this by balancing the direction of the blast along the vertical (upward) and perpendicular planes of the muzzle to lower muzzle rise. The ports on the Dynacomp are ball dimpled for smooth expansion of gases and rapid heat dissipation. The front of the device is 0.25" thick to better handle the abuse of full auto fire.
