Radical Firearms BTR 7.62x39mm 10.5" Barrel AR Pistol - FP105762X39HBAR10RPRBT

The Radical Firearms BTR 7.62x39mm delivers the stopping power of the AK platform in an AR-15 format with enhanced modularity and familiar controls. This 10.5-inch barrel configuration provides optimal velocity retention while maintaining maneuverability in confined spaces.

What Makes This Different

Unlike traditional 7.62x39mm platforms, the BTR system utilizes standard AR-15 lower receivers and trigger groups while incorporating a purpose-built upper designed specifically for the Soviet cartridge. The 10.5-inch heavy profile barrel maximizes powder burn efficiency, delivering approximately 2,200 fps with 123-grain ammunition. Enhanced bolt face geometry and modified bolt carrier group ensure reliable extraction and ejection with steel-cased ammunition.

Key Features

• 10.5-inch heavy profile barrel optimized for 7.62x39mm ballistics
• Enhanced bolt carrier group with improved extractor for steel-cased reliability
• Standard AR-15 lower compatibility with existing triggers and furniture
• M-LOK compatible handguard for accessory mounting
• A2 flash hider reduces muzzle flash and concussion
• Mil-spec buffer tube accepts standard AR pistol braces
• Hard coat anodized finish resists corrosion and wear

Field testing demonstrates consistent 2-3 MOA accuracy with quality ammunition, making this platform suitable for close-quarters applications, truck gun roles, and hunting within 200 yards. The shorter barrel length reduces overall weapon system weight to approximately 6.5 pounds while maintaining sufficient velocity for effective terminal performance. Corrosion-resistant coating withstands humid conditions and extended storage periods.
