If you shoot a Ruger American Rifle in .450 Bushmaster, you know that cartridge hits hard—which means it recoils hard. The Ruger 90641 muzzle brake for Ruger American 450 Bushmaster is engineered to tame that impulse, giving you better control and accuracy as you work through a shooting string. By redirecting gases to manage recoil, this brake lets you stay on target longer and shoot more comfortably, whether you're hunting or running drills at the range.
This is a straightforward, no-frills brake that does the job without overthinking it. It threads onto your barrel with a standard 11/16-24 TPI fit, clocks into position with an external jam nut, and secures in seconds using a basic box wrench or crescent wrench. The design also helps manage noise and blast signature to the sides, which your shooting buddies will appreciate. Built from alloy steel with a matte black finish, it's tough and ready for field use.
Ruger manufactures this brake in the USA, so you're getting a domestically made part that matches your rifle's quality standard. At 3 ounces and just over 2 inches long, it adds minimal length to your setup while delivering real recoil management where you need it most.
