The Radical Firearms AR-15 Pistol is a compact and versatile firearm based on the AR-15 platform but designed in a pistol configuration. The AR-15 Pistol retains the essential features of the AR-15 platform, such as a semi-automatic action, detachable magazine, and compatibility with various AR-15 components and accessories. However, it lacks a traditional shoulder stock and is equipped with a stabilizing brace instead. AR-15 pistols typically have shorter barrels compared to their rifle counterparts. Common barrel lengths for AR-15 pistols range from 7.5 inches to 11.5 inches, offering increased maneuverability in close quarters while sacrificing some velocity and ballistic performance. AR-15 pistols can be chambered in various calibers, including the popular 5.56 NATO/.223 Remington, as well as alternative options such as .300 Blackout or 9mm. The caliber choice determines factors like ammunition availability, recoil, and terminal ballistics. Unique features of Radical Firearms AR-15 pistols or specific models they offer may include proprietary handguards, adjustable braces, ambidextrous controls, enhanced triggers, and muzzle devices designed to reduce recoil and improve stability.
