The then, 26-year old Theresa, is a Michigan EMT and professional wild game hunter who says she has been cross-country hunting with her dad for as long as she can remember. It shows in the way Theresa handles this 50cal sniper rifle! What an amazing shot, take a look.
The M82 is a short-recoil semi-automatic 50 Cal sniper rifle. When the gun is fired, the barrel initially recoils for a short distance (about 1 in (25 mm)), while being securely locked by the rotating bolt. After the short travel, the lower part of accelerator arm, held by receiver upper part, is already hinged in bolt carrier and the middle portion strikes it back to the barrel by a rod place in bolt carrier, transferring part of the recoil energy of the barrel to the bolt to achieve reliable cycling and unlock it from barrel. The bolt is unlocked by turning in the curved cam track in the bolt carrier. Then, the barrel is stopped by the combined effect of the accelerator, buffer spring and the muzzle brake and the bolt continues back, to extract and eject a spent case.[clarification needed] On its return stroke, the bolt strips the fresh cartridge from the box magazine and feeds it into the chamber and finally locks itself to the barrel. The striker is also cocked on the return stroke of the bolt. The gun is fed from a large, detachable box magazine holding up to 10 rounds, although a rare 12-round magazine was developed for use during Operation Desert Storm in 1991.
The receiver is made from two parts (upper and lower), stamped from sheet steel and connected by cross-pins. The heavy barrel is fluted to improve heat dissipation and save weight, and fitted with a large and effective reactive muzzle brake. On the earlier models, the muzzle brakes had a round cross-section; later M82 rifles are equipped with two-chamber brakes of rectangular cross-section.
