The M82 is a short recoil semi-automatic firearm. When the gun is fired, the barrel initially recoils for a short distance (about 1 in/25 mm) being securely locked by the rotating bolt. After the short travel, a post on the bolt engaged in the curved cam track in the receiver turns the bolt to unlock it from the barrel. As soon as the bolt unlocks, the accelerator arm strikes it back, transferring part of the recoil energy of the barrel to the bolt to achieve reliable cycling. Then the barrel is stopped and the bolt continues back, to extract and eject a spent case. 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 also is 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.
Nowhere is this more apparent than in the Barrett Model 82A1. For more than two decades, this short-recoil, semi-automatic series rifle has been carefully honed, studied and then refined again. The result is a feat of engineering so impossibly precise, it’s hard to believe it’s man-made.
Unlike other semi-automatic .50 BMG rifles, the Barrett Model 82A1 is completely reliable. Its chamber is chrome-plated and dimensioned for both civilian and military ammunition. The extractor and ejector are proven to work under any condition, and close tolerances on every part allow it to function in all environments.
The new .416 caliber alternative further adds to the allure of the Barrett Model 82A1. With enhanced accuracy and stability, not to mention a
significantly higher muzzle velocity, the .416 offers incredible long-range precision.
