The Spike’s Tactical Dynacomp Short is a 5.56 muzzle device 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, while the end of the device restricts forward energy to reduce parallel recoil.
 
The ports on the Dynacomp are ball dimpled for smooth expansion of gases and rapid heat dissipation. The entire device is nitride treated to enhance these characteristics and provide a slick black finish
