RADICAL FIREARMS Zero Impulse A2 1/2x28 (ZS556)

The Radical Firearms Zero Impulse Muzzle Brake features a highly effective, patent pending three chamber design that redirects high pressure gasses. This significantly reduces both felt recoil and muzzle rise, aiding the shooter in staying on target even during full auto fire. The rear-angled side ports with generous top ports are exceptionally effective, allowing for faster follow-ups and dramatically reducing the effort required to stay on target. Machined from a solid piece of 4150 chrome moly steel and finished with an exceptionally corrosion resistant salt bath Nitride, this AR-15 muzzle device is highly durable as well!
