Ruger 90486 Radial Ported Muzzle Brake AR-15 5.56/.223 1/2x28

The Ruger 90486 Radial Ported Muzzle Brake delivers substantial recoil reduction and muzzle rise control for AR-15 platforms chambered in 5.56 NATO and .223 Remington. This precision-engineered brake redirects propellant gases through strategically positioned radial ports to counteract both vertical climb and felt recoil.

What Makes This Different

Unlike traditional linear compensators, this radial port design disperses gases in a 360-degree pattern around the shooter rather than directing blast forward or to the sides. The black oxide finish provides superior corrosion resistance compared to standard steel treatments while maintaining a low-profile appearance. At just 1.75 inches overall length, it adds minimal weight and bulk to the rifle while delivering measurable performance improvements.

Key Features

• Radial port configuration reduces felt recoil by up to 30% compared to standard flash hiders
• Black oxide steel construction resists corrosion and wear under high round counts
• Standard 1/2"-28 TPI threading fits most AR-15 barrels without modification
• 0.75" diameter maintains clean sight picture with low-profile gas blocks
• 1.75" overall length minimizes added weight and maintains rifle balance
• Precision-machined ports ensure consistent gas dispersion and performance
• Compatible with 5.56 NATO and .223 Remington chamberings

Range testing demonstrates significant improvement in follow-up shot speed and target reacquisition. The radial port design proves particularly effective during rapid-fire sequences and competition shooting where muzzle control directly impacts accuracy. Steel construction handles sustained fire sessions without degradation, making it suitable for both recreational shooting and professional applications. The black oxide finish maintains its appearance through thousands of rounds and various weather conditions.
