RISE Armament designed its Rise Armament 1121XR Semi Auto Rifle for those who want more out of a heavy-caliber gas rifle. With the 1121XR, big-game hunters can have accurate knock-down power at long distances without having the extra weight that typically comes with such a platform. Competitors and long-range shooters can have the accuracy of a bolt-action gun with the benefit of quick follow-up shots due to minimal recoil and muzzle bounce.
