Radical Firearms RBR10-308-20 | .308 Win | 20″

The Radical Firearms RF-10 RBR10-308-20 is an AR-style modern sporting rifle chambered in .308 Winchester built with billet 7075-T6 upper and lower receivers and a 20″ stainless-finish barrel. The 15″ low-profile free-float M-LOK rail provides ample accessory space while preserving a stable barrel platform for accuracy. Ergonomics include a 6-position B5 Bravo stock and an MFT Engage grip for a familiar AR feel.

For an optic under $1,000 that pairs well with this platform consider the Vortex Viper PST Gen II 1-6×24 — it covers close-to-mid ranges suitable for this rifle’s applications. Typical uses for this rifle include precision target work at the range and medium-game hunting.
