The Radical Firearms 300 BLK Pistol has been upgraded for 2019 with the popular SB-Tactical SBA3 5 position adjustable pistol brace. This arm brace is extremely durable and rigid with plenty of adjustment for different arm lengths and features a QD sling swivel slot for carrying or added stability when shooting off hand. It also allows for a proper cheek weld giving you a variety of ways to shoot your AR pistol. This model comes with a 10.5” barrel machined from 4140 Chrome Moly steel with a Melonite finish and the 1:8 twist rate is a good middle ground for shooting lightweight supersonic bullets and heavier subsonic bullets, if you plan on running suppressed. The pistol length gas system is necessary to reliably cycle this cartridge and the M4 feed ramps help to feed each round into the chamber. The Radical Firearms .300 Blackout pistol paired with the SBA3 stabilizing brace make this gun extremely fun at the range.

However, it does come with an ambidextrous safety selector, Mission First Tactical Ergo pistol grip, and a billet machined magazine button. Also included is the Radical Firearms 10” RPR M-LOK handguard. This handguard comes with a few features of its own like an extremely durable barrel nut that free floats the barrel for better accuracy and indexes with the upper receiver to prevent it from rotating loose.
