The Armalite AR-50A1 is the newest incarnation of the wildly popular AR-50 chambered for the powerful .50BMG cartridge - a single-shot, bolt-action rifle featuring a unique octagonal receiver bedded down into a V-shaped stock. Designed to be an economical answer for the challenges of long range shooting, the AR-50A1 is amazingly accurate and, with its massive muzzle brake, it has a very manageable recoil.
