300 Blackout is one of the most popular calibers for AR pistols because of its short barrel performance as well as suppressor performance. This Radical Firearms AR pistol is built from high quality Mil-Spec components to ensure reliable function and compatibility with aftermarket parts. The barrel on this 300 Blackout pistol is made from 4140 chrome moly vanadium steel and features a harder than chrome Melonite finish. This type of finish is also applied to the bolt carrier group to increase wear and corrosion resistance as well as the overall life span of the components. Covering the 8.5” barrel is the Radical Firearms FCR M-LOK handguard. This handguard features a free float design that indexes with the upper receiver to prevent any misalignment that can affect your zero. With M-LOK attachment points and a full length picatinny top rail, you can quickly and easily attach your favorite lights, angled foregrips, and other accessories. If you are in the market for a reliable and affordable AR-15 pistol, Radical Firearms has plenty of options to choose from to fit your needs.

Outfitted to the end of the 1:7 twist barrel is a standard A2 flash hider that can easily be removed if you plan on attaching a suppressor or other aftermarket muzzle device. The 1:7 twist rate is optimal for stabilizing the slower and heavier subsonic rounds but is also capable of being accurate with lighter rounds making it a great all-around twist rate. In order to reliably cycle the action, a pistol length gas system and buffer tube are used. This combination ensures that whether you are shooting subsonic or supersonic ammo, your pistol will function. Another feature of this 300 BLK pistol is the Mission First Tactical pistol grip that provides better ergonomics and the ambidextrous safety selector makes right or left-handed shooting more convenient. All that is left for you to purchase is your favorite ammo and optic and you are ready for the range.
