Product Info for Ultradyne Pegasus Compensator, .223/5.56

PEGASUS has been meticulously engineered to provide superior recoil reduction and neutralize muzzle rise with a smooth, balanced release of blast energy in a tanker-style compensator. 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.image
