Barrett 7
The chamber is divided into two parts (upper and lower), and the thin steel plate is stamped and then fastened with cross bolts. Pen, fun, pavilion www. biquge。 The INFO barrel has recessed holes for increased heat dissipation and weight reduction, and is also fitted with a large and effective muzzle brake. Early muzzle brakes were cylindrical arrows, and the new M82 was fitted with double-bore right-angled arrow-shaped (V-shaped) brakes. This brake reduces recoil by nearly 70%. The flaw was that the gunpowder gases ejected from the brake emitter would roll up a large amount of dust and loose particles near the shooter with each bullet fired.
The M82A1 can be aimed with a scope and a folding front sight in case the scope is damaged. The U.S. M82 is usually equipped with a LeupoldMark 4 telescope, while the M82A1M (Marine Corps M82A3) has a long tactical rail and a U.S. military optical telescope, so more aiming accessories are available. All M82s have foldable handlebars and bipods (both can be removed in the M82A3). The M82A3 has a split stock with soft padding inside the stock and a special rubber backseat cushion to offset the firing recoil, which is said to be smaller than that of 12-gauge shotguns and 7.62mm caliber rifles. The M82A1 and M82A3 can be mounted on an M3 or M122 tripod (for machine guns) or on some vehicle vehicles as a "Barrett soft tow". The M82A1 has a folding front sight, however, in actual combat the M82 is difficult to aim with a conventional front sight because of its weight and length.
The M82A2 differs from the M82A1 mostly in the structure: the grip and trigger are before the magazine, and the butt is advanced a little behind the chamber, almost close to the magazine. The plus foregrip was under the barrel, and the scope was moved forward some distance.
Collapse edit this paragraph to use ammunition
The 12.7x99mm NATO machine gun cartridge (.50BMG) has a complete range of ammunition, with the M82/M107 rifle mainly using the following types of ammunition
M33 ordinary shell
Standard ammunition for M82/M107 with a warhead weighing 45.8 grams,
Number: STD-OTCM36841, no identifying color. The cartridge case contains 15.23 grams of WC860 bistatic propellant, with a chamber pressure of 379MPa. It can penetrate 8 mm thick steel plates at 500 meters and 4 mm thick steel plates at 1200 meters. M107 has been using this kind of bullet for long-distance sniping in the early days.M33 bullet tip is equipped with about 0.8 grams of sodium carbonate monohydrate.Sodium carbonate monohydrate is a white powder, the melting point is as high as 851 °C, the performance is stable, after the warhead hits the target, the warhead ruptures, releasing white powder to form smoke, which is convenient for the shooter to observe the impact point, and then correct the trajectory.
Norway Raufoss Class A Race Bomb
The DODIC code A606, which is only used by the U.S. Marine Corps USMC, is issued to M82 shooters as standard ammunition. The muzzle velocity is 854 m/s, and the effective range reaches 1800 meters when performing anti-materiel missions.

Ronnie Barrett was originally a commercial photographer in Tennessee, USA, and a firearms enthusiast with no training in firearms design. In January 1981, a chance encounter prompted Barrett to design a large-caliber semi-automatic sniper rifle. So, from design to manufacturing, he came up with a prototype gun in less than a year. Then Barrett created his own company, and in 1982 began trial production, and the M82A1 large-caliber semi-automatic sniper rifle was officially "born".
