Ruger American Muzzle Brake 11/16x24 Matte Black Alloy Steel 45-70 Gov/450 Bushmaster

The Ruger American Muzzle Brake (part 90641) is a factory recoil-taming accessory designed specifically for the Ruger American Ranch rifle chambered in .450 Bushmaster and compatible .45-70 Government lever-action platforms. Machined from durable alloy steel with a low-glare matte black finish, this muzzle device threads directly onto the barrel using the 11/16"x24 thread pattern standard to those big-bore Ruger configurations.

At just 2.20 inches overall length and 1 inch in diameter (approximately 3 oz), the brake adds minimal weight and length to the host rifle while meaningfully reducing felt recoil and muzzle rise. By stabilizing the rifle during follow-up shots, it contributes to improved accuracy over a longer string of fire, making it a smart upgrade for hunters and recreational shooters working with the stout .450 Bushmaster and .45-70 Gov't cartridges. Designed and made in the USA to Ruger's quality standards, this is a genuine factory accessory, not an aftermarket substitute.

Installation is straightforward: the brake threads onto any Ruger American Ranch .450 Bushmaster barrel or compatible .45-70 Government barrel cut with the matching 11/16"x24 pitch. The right-hand design and matte finish blend cleanly with factory barrels. If you are looking to tame the recoil of your big-bore Ruger, the 90641 American Muzzle Brake is the correct factory-spec component for the job.
