The SFAR’s engineering centers on a scaled, high-strength bolt carrier group and a proprietary barrel extension that handles .308 pressures in a compact footprint. The 1:10″ twist rate stabilizes a broad spectrum of bullet weights from 150 to 180 grains, making it effective for hunting, target shooting, and tactical use. Its adjustable gas system ensures reliability whether using commercial match or surplus 7.62 NATO ammunition.
