GRIZZLY - MUZZLE BRAKE BLUED - THREAD: 5/8X24TPI - DIA: 21.65MM - SKU: GB21.65
Australian made muzzle brakes.
The GB21.65 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.
The GB21.65 standard thread size is:
- 5/8x24TPI
The GB21.65 Dimensions are 21.65mm (0.852in) diameter, 63.55mm (2.501in) in length and it weighs 90 grams (23.17oz).
The GB21.65 Barrel profile and thread match perfectly for the following firearms for a flush fitting muzzle brake:
- Howa Varmint
- Remington Varmint
- Kimber Varmint
The GB21.65 is also suitable for many other firearms for a flush fitting muzzle brake that have this barrel profile. It can also be fitted to a smaller barrel profile, if the 5/8x24TPI thread size is what you require and a slightly larger diameter brake is prefered.
