Chambered in .50 BMG, this AR-50A1 uses a 30-inch heavy-profile chrome-moly barrel marked "50 BMG" with a multi-chamber side-port muzzle brake. The barrel is threaded, and the 1:15 RH twist supports .50-caliber projectiles. Capacity is one round via its single-shot action, with a large right-side ejection/loading port.
The octagonal receiver is mated to the aluminum chassis using machine-rest style V-block bedding. Overall length is approximately 58.5 inches, and weight is about 37.1 pounds.
The aluminum stock includes an adjustable cheekpiece and adjustable buttplate, plus a rubber buttpad and a collapsible rear monopod. Length of pull is 15.0 inches. A textured finger-groove pistol grip provides a firm hold, and a two-position bolt-shroud safety controls the action.
The long, grooved aluminum fore-end features a full-length underside accessory slot and carries the installed bipod. The rifle is fitted with a scope mount, and factory canted scope rails ship with a 15 MOA cant. Made in the United States.
