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. Bushmaster literature says that the rifle recoils like a .243 Winchester. The barrel has a MIL-STD-1913 rail (Picatinny style) for mounting a rifle scope.

The BA50 was the original design of Cobb Manufacturing. Bushmaster purchased the design and upgraded it and released it as the Bushmaster BA50.

Bushmaster states that the rifle is capable of shooting 1 minute of angle (MOA) with M33 ball ammunition.

In 2020 Remington, who owns Bushmaster, rebranded the rifle to be released as the "R2Mi."^[1]
