Radical Firearms

Overview

The Radical Firearms 10.5" 300 Blackout Pistol Length Barreled Upper is a complete upper assembly designed specifically for the AR-15 platform. With a 10.5-inch barrel and a 1:8 twist rate, it provides optimal stabilization for a wide range of bullet weights, making it ideal for both subsonic and supersonic loads. The pistol-length gas system enhances reliability and cycle speed, which is particularly beneficial for tactical and close-quarters applications. This upper is commonly found in builds that focus on the 300 Blackout caliber with a pistol gas system.
