Radical Firearms RF-15 300BLK 10.5″ HBAR Pistol | M-LOK

The Radical Firearms RF-15 is an AR-style pistol chambered in .300 AAC Blackout with a 10.5″ HBAR-profile barrel and a 10″ RPR free-float M-LOK handguard. It uses forged MIL-STD upper and lower receivers finished with Type III anodizing and a pistol tube buffer assembly. For a reliable optic that pairs well with this platform, consider a compact red dot such as the Holosun HS507C (well under $1,000) mounted to the top Picatinny rail.

Typical applications include precision-range practice and short-range hunting or varmint work; the platform also accepts suppressors and accessory configurations commonly used for controlled-range or field work.
