ULTRADYNE MERCURY COMP 6.5CM 5/8X24

The Mercury Muzzle Brake has been engineered to precise specifications to provide superior recoil reduction and inhibit muzzle rise with a calibrated release of blast energy. Progressive 90-degree side ports re-direct combusting gases at precise intervals to disperse the recoil impulse for efficient follow-up shots. With an included timing nut, the Mercury can be indexed for optimal performance.
