This muzzle brake is 26cal (.264) to 30cal (.308) an has 14x1 muzzle thread. You will also need a 14x1 jam nut to time brake or use a crush washer etc for install.
The Gas Mongrel Hybrid (GMH) was created to be the best of both the WR Ultra Comp and the WR Gas Mongrel muzzle brakes (each the world best in their class).Using the best of WR design specs from the GM and UC brakes, the GMH more so polarises gas direction and dispersion to increase gas velocity to the sides of the bullet axis, reducing felt blast while continuing to minimise muzzle movement during bullet exit.If your needs are for maximum brake, minimal muzzle movement and bounce, minimal ground disturbance, reduced felt blast and slimline brake for practical applications, the Gas Mongrel Hybrid is the best pound for pound brake in the world. It doesn’t get better than this.Reduce muzzle walk with increasing shot-to-shot heat build-up. The GMH is made ULTRA lightweight, thanks to being made from 7075 Aluminium, and a massive increase in surface area will considerably help absorb and dissipate heat away from the muzzle area.Like all WR brakes, we continue to campaign the non-integrated clock nut. Why? Our math and simulations show modulus of elasticity is causing many disturbances we wish to avoid. WR are advocates for a straight brake thread to a jam nut off the brake shoulder as the BEST fitment method.
