Radical Firearms AR Pistol: Compact Performance
The Radical Firearms AR Pistol represents a thoughtful approach to compact rifle design. Built on mil-spec principles, this 5.56mm platform delivers the accuracy and reliability shooters expect from quality AR-pattern firearms.
Barrel and Action
Barrel Construction: The 7.5" barrel is forged from 4140 chromoly vanadium steel and finished with Melonite treatment—a process that creates a harder-than-chrome surface. This finish extends to the bolt carrier group, reducing receiver wear and enhancing long-term reliability.
- Profile: M4 with 1:7 twist rate
- Chamber: 5.56mm NATO
- Thread Pitch: 1/2x28 for standard muzzle devices
- Gas System: Pistol-length with low-profile .750" gas block
- Muzzle Device: A2 flash hider included
Receivers and Controls
Both upper and lower receivers are forged from 7075 T6 aluminum with Type III hard-coat anodizing. All controls—charging handle, safety selector, and fire control group—meet MIL-STD specifications. The forward assist and dust cover are standard mil-spec components.
Handguard and Ergonomics
The 7" free-float RPR handguard keeps your hands away from the barrel while providing M-LOK slots on the sides and bottom for mounting accessories. Free-floating design supports accuracy by isolating the handguard from the barrel.
Magazine and Buffer System
The pistol comes with a 30-round 5.56mm magazine and uses a pistol-tube buffer system appropriate for the shorter gas system.
The Bottom Line
This is a no-nonsense AR pistol built to mil-spec standards. Whether you're new to the platform or adding to an existing collection, the Radical Firearms AR Pistol delivers solid performance in a compact package.
