R-10 Killdeer


R-10 Killdeer


All rifles are made to order. Please allow 4 weeks to ship. 

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 Killdeer weighs less than many AR-15s. Built from the ground up, focusing on hunters’ needs, the R-10 Killdeer does not compromise accuracy or durability while weighing in at 6.51 lbs. Built as an SR25/DPMS variant, the R-10 Killdeer comes standard with a Cerakote® finish, and premium components such as the KynSHOT™ Recoil Reducing Buffer, Radian® ambidextrous charging handle, and PROOF Research® carbon fiber barrel.  Not only are PROOF Research barrels exceptionally accurate but, like ROAM, they have managed to create a lightweight product without sacrificing performance or structural integrity. This pairing creates an incredibly light rifle that can hold its own in the field or in competition. Whether it’s a day at the range or a once in a lifetime bull Elk hunting trip, the R-10 will let you travel light and roam far™.
