R-10 Walhalla


R-10 Walhalla


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

The R-10 Walhalla is one of the first AR-style rifles designed with the long-range hunter in mind. Chambered in 6.5 Creedmoor while weighing in at just 6.82 lbs, this rifle allows the hunter to stretch his legs and his effective range. Superior ballistic coefficients of the 6.5 Creedmoor offer flatter trajectories and reduced wind drift to allow shooting out to 1,000 meters or more. Utilizing unique magnesium alloys that match the strength of aluminum while dropping a third of the weight, the R-10 Walhalla brings unprecedented weight reduction to the AR platform without compromising integrity. Built as an SR25/DPMS variant, the R-10 Walhalla 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™.
