Strike Industries JCOMP Gen2 AR 308 Winchester/7.62mm NATO Muzzle Brake - 5/8 x 24

Strike Industries JCOMP Gen2 AR 308 Winchester/7.62mm NATO Muzzle Brake - 5/8 x 24 - The SI JCOMP Gen2 takes the proven Type 89 compensator design and re-engineers it for today’s demanding shooters. Inspired by the iconic muzzle device of the Japanese Type 89 rifle, this updated version retains the features shooters loved—while delivering even greater recoil control and muzzle rise reduction.

Enhanced port geometry provides improved muzzle compensation, keeping your sights on target for quicker follow-up shots and tighter shot strings. Whether you're running drills, competing, or training hard, the JCOMP Gen2 helps you stay fast, controlled, and accurate.

The Gen2 is also compatible with Oppressor and FerFrans concussion reduction devices, giving you the flexibility to redirect blast forward when shooting indoors or alongside teammates.

The original concept traces back to the compensator design used on Japan’s Type 89 service rifle—fielded by elite military and security units. The Gen2 refines that heritage with updated engineering, improved performance, and modern manufacturing standards.
