Ruger Glenfield 90806 450 Bushmaster 11/16x24 Muzzle Brake

The Ruger Glenfield 90806 is a hybrid muzzle brake purpose-built for rifles chambered in 450 Bushmaster. Machined from rugged alloy steel and finished in a low-glare black oxide coating, this muzzle device is engineered to tame the stout recoil of the big-bore straight-wall .450 cartridge and keep the muzzle flat for faster follow-up shots on hogs, deer, and other North American game.

The 90806 uses an 11/16x24 thread pattern, the factory standard for 450 Bushmaster rifles, and is timed using an external jam nut so the shooter can index the brake precisely on the barrel and lock it in place. Its hybrid port geometry blends side-facing recoil-attenuating vents with top-facing compensation, redirecting propellant gas to control muzzle rise through the full firing cycle. The black oxide finish is built to complement most factory rifle bluing and coatings.

Measuring approximately 5.6" long, 2.2" wide, and 1.3" tall and weighing roughly 0.21 lb, this is a direct-fit upgrade or replacement brake for any 450 Bushmaster barrel cut to the correct 11/16x24 pitch, including the Ruger Ranch and Ruger American rifle platforms.
