The Franklin Armory M4-HTF R3 XTD rifle in .350 Legend with a black hard-coat anodized finish (brand part no. 0010055BLK) is a semi-automatic AR-pattern rifle built around a light-contour 16-inch barrel topped with an Aura XTD muzzle device. Franklin Armory cuts a 1:12-inch twist into the barrel and fits a custom-tuned trigger for a crisper pull than a standard AR trigger group. The rifle feeds from a 10-round magazine and ships optic-ready with no fixed sights, paired with an adjustable B5 Bravo stock and B5 grip in a right-hand configuration. A mil-spec safety selector rounds out the design. Among straight-wall-cartridge semi-auto rifles, the M4-HTF R3 XTD favors hunters who want AR ergonomics in a straight-wall-legal caliber.
