Product description
Aggressive and Effective – Muzzle Brake for .223 | 5.56 AR15
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 90º 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.

MERCURY is the choice for those seeking a compact, lightweight muzzle device with smooth recoil characteristics. A timing nut is included for easy installation.
