Radical Firearms 7.5" AR Pistol 5.56 NATO M-LOK Rail System

The Radical Firearms FP75556M47RPRBMPSB delivers compact firepower in a 7.5-inch barrel configuration optimized for close-quarters applications. This AR-style pistol combines proven direct impingement operation with modern manufacturing standards to create a reliable platform for tactical use and sporting applications.

What Makes This Different

The 7.5-inch barrel length provides maximum maneuverability while maintaining effective terminal ballistics within 200 yards. Radical Firearms constructs this pistol with a forged 7075-T6 aluminum upper and lower receiver set, offering 30% greater strength than standard cast components. The M-LOK compatible handguard system allows for streamlined accessory mounting without the bulk of traditional quad-rail designs.

Key Features

• 7.5-inch 4150 chrome moly vanadium barrel with 1:7 twist rate for stabilizing heavier projectiles
• Forged 7075-T6 aluminum receiver set with Type III hard coat anodizing
• M-LOK handguard system with continuous top rail for optics mounting
• Standard AR-15 magazine compatibility accepts all STANAG pattern magazines
• A2 flash hider reduces muzzle flash and protects crown threads
• Mil-spec trigger group with standard AR-15 parts compatibility
• SB Tactical pistol stabilizing brace for enhanced control

This configuration excels in vehicle operations, home defense scenarios, and competitive shooting disciplines requiring rapid target transitions. The shorter barrel reduces overall length to 26 inches while maintaining reliable cycling with standard 5.56 NATO and .223 Remington ammunition. Weather-resistant finishes and quality control testing ensure consistent performance across temperature extremes and adverse conditions.
