The Radical Firearms FP75556M47RPR delivers compact firepower in a precision-engineered AR pistol platform. This 5.56x45mm NATO chambered firearm combines a short 7.5-inch barrel with proven reliability for close-quarters applications. Built on a forged upper and lower receiver set, it maintains structural integrity under demanding conditions.
What Makes This Different
The forged construction sets this pistol apart from cast alternatives, providing superior strength-to-weight ratio and consistent dimensions. The 7.5-inch barrel length optimizes maneuverability while maintaining effective terminal ballistics within 200 yards. Cold hammer forging ensures bore consistency and extends barrel life compared to button-rifled alternatives.
