The Bushmaster BA50 is a bolt-action, magazine-fed rifle designed to shoot the .50 BMG cartridge.
It has a 22- (carbine) or 30-inch, match grade Lothar Walther free-floating barrel with a 1-in-15-inch twist rate (standard for the .50 BMG cartridge).
The rifle weighs 30 pounds (without a magazine or ammunition) and has a muzzle brake to help tame the recoil.
The barrel has a MIL-STD-1913 rail (Picatinny style) for mounting a rifle scope.
Bushmaster states that the rifle is capable of shooting 1 minute of angle (MOA) with M33 ball ammunition.
