Barrett M82/M107

The M82, standardized by the US Military as the M107, is a recoil-operated, semi-automatic anti-materiel rifle developed by the American Barrett Firearms Manufacturing company. It is used by many units and armies around the world. Despite its designation as an anti-materiel rifle, it is used by some armed forces as an anti-personnel sniper rifle. It is also called theLight Fifty for its .50 BMG (12.7×99mm NATO) chambering. The weapon is found in two variants, the original M82A1 (and A3) and the bullpup M82A2. The M82A2 is no longer manufactured, though the XM500 can be seen as its successor.

A WHOLE NEW LEGEND.

It may be related to the Model 82A1®/M107®, but the M107A1 is far from a simple evolution. Driven by the demands of combat, every component was re-engineered to be lighter yet stronger. The result? A high-performance rifle that weighs five pounds less than the original M107, but is every bit as tough.Designed to be used with a suppressor, this one-of-a-kind rifle allows you to combine signature reduction capabilities with the flawless reliability of the original Barrett M107, but with a rifle weight reduction of 5 pounds. An all new bolt carrier group has been designed and is key to making the rifle suppressor-ready. Its steel four-port cylindrical muzzle brake is engineered to work seamlessly with a quick-attach Barrett QDL Suppressor.The lightweight aluminum upper receiver features an integrated 27 MOA optics rail. Inside the upper receiver, the bolt carrier rides on a hardened steel anti-wear strip for added durability. A thermal-guard cheek piece protects the user's face from extreme heat or cold.Advanced design and manufacturing make the M107A1 more precise than ever. The rear barrel stop and front barrel bushing are bolted and bonded with a high strength compound. A titanium barrel key and fully-chrome-lined bore and chamber add to the rifle's durability.Enhanced modularity is also a key feature of the M107A1. The rail-mounted aluminum rear grip can easily be reconfigured. The newly designed titanium and polymer monopod is adjustable from either side.The M107A1 rifle's lower receiver includes a new aluminum recoil buffer system that's optimized for use with the Barrett QDL Suppressor. The bolt carrier's components are protected with a mix of ultra-hard coatings and advanced nickel Teflon® plating that increases lubricity, is corrosion-resistant and greatly eases cleaning.Numbered witness holes on the magazine are just another example of how even the smallest detail makes a powerful difference.Retail price list reflects U.S. commercial sales only.

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 or 25 mm), while 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 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 flutedto 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.

M82A1 rifles are fitted with scope mount and folding backup iron sights, should the glass scope break. The U.S. military M82 rifles are often equipped with Leupold Mark 4 telescopic sights. The M82A1M (USMC M82A3) rifles have long Picatinny accessory rails mounted and US Optics telescopic sights. Every M82 rifle is equipped with a folding carrying handle and a folding bipod (both are detachable on the M82A3). The M82A3 is also fitted with a detachable rear monopod under the butt. The buttpad is fitted with a soft recoil pad to further decrease the felt recoil. M82A1 and M82A3 rifles could be mounted on the M3 or M122 infantry tripods (originally intended for machine guns) or on vehicles using the special Barrett soft-mount. The M82A1 can be fitted with a carry sling but according to those who carried it in the field, the M82 is too uncomfortable to be carried on a sling due to its excessive length and weight. It is usually carried in a special carry soft or hard case.

The M82A2 differed from M82A1 mostly in its configuration— the pistol grip along with trigger was placed ahead of the magazine, and the buttpad placed below the receiver, just after the magazine. An additional forward grip was added below the receiver, and the scope mount moved forward.

The maximum effective range of the M107 is 1,830 metres (2,000 yd). The maximum range of this weapon (specifically the M107 variant) is 4,000 metres (4,400 yd), as quoted in the owner's manual. Fifty caliber (and larger) rounds have the potential to travel great distances if fired in an artillery-like fashion, necessitating the observance of large safety margins when firing on a range.
