GRIZZLY - MUZZLE BRAKE STAINLESS - THREAD: M18X1P - DIA: 20.7MM - SKU: GBS20.7
Australian made muzzle brakes.
The GBS20.7 Grizzly muzzle brake is designed for calibres up to .30cal. These brakes are an easy, convenient screw on design that do not require any crush washers or special tools. Just screw the muzzle brake on all the way to the shoulder of your barrel and then fasten tight with the tool provided. Due to the perfectly aligned machined gas ports, this design disperses energy evenly around the brake, creating greater balance thus eliminating deviation from the muzzle blast.
PLEASE NOTE - Calibres over .30cal must be modified by a gunsmith.

- M18X1P
The GBS20.7 Dimensions are 20.7mm (0.814in) diameter, 63.22mm (2.489in) in length and it weighs 70 grams (2.46oz).

The GBS20.7 is also suitable for many other firearms for a flush fitting brake that have this barrel profile. It can also be fitted to a smaller barrel profile, if the M18x1P thread size is what you require and a larger diameter is prefered.
