Product Description
MERCURY has been meticulously engineered for the .223/5.56 caliber to provide superior recoil reduction and neutralize muzzle rise with a smooth, balanced release of blast energy. Progressive 90 side ports vent combusting gases at intervals that spread out the recoil impulse for efficient, accurate follow-up shots. Like all Ultradyne muzzle devices, a timing nut is included for easy installation.
Features
- 1/2X28 thread pitch
- 416 stainless steel
