The R-10 is the first in a new generation of AR-style rifles. Utilizing unique magnesium alloys, this rifle sheds weight without compromising integrity. Chambered in .308 Winchester, the R-10 Red River Ultralight weighs less than many AR-15s. Built from the ground up, focusing on hunters’ needs, the R-10 Red River Ultralight does not compromise accuracy or durability while weighing in at 5.92 lbs. Built as an SR25/DPMS variant, the R-10 Red River Ultralight comes standard with a Cerakote® finish, and premium components such as the Radian® ambidextrous charging handle, Hogue® pistol grip, and MFT™ collapsible buttstock. Whether it’s a day at the range or your annual whitetail hunt, the R-10 will let you travel light and roam far™.
