Ruger 90486 Radial Ported Muzzle Brake Black Oxide Steel 1/2x28 5.56 NATO

The Ruger 90486 Radial Ported Muzzle Brake is a factory recoil-mitigation accessory machined from steel and finished in a low-glare black oxide coating. Purpose-built for 5.56 NATO and .223 Remington rifles, the radial port geometry directs expanding gases to reduce felt recoil and tame muzzle rise and lateral movement during rapid fire.

The brake installs on any barrel wearing the standard 1/2"x28 thread pattern common to .223/5.56 platforms. At just 1.75" overall length and .75" diameter, it keeps a compact front-end profile without weighing the rifle down. Mounting is straightforward using a common 11/16" open end wrench — no specialty tools or shims required.

Designed and built by Ruger to match the fit and finish of their firearms, the 90486 delivers factory-engineered recoil control in a durable, all-steel package.
