Barret .50 Calibur snipers Rifle.

The Barrett Firearms Company was founded by Ronnie Barrett for the single purpose of building semi-automatic rifles chambered for the powerful 12.7x99mm NATO (.50 BMG) ammunition, originally developed for and used in M2 Browning machine guns. Barrett began his work in the early 1980s and the first working rifles were available in 1982, hence the designation M82. Barrett continued to develop his rifle through the 1980s, and developed the improved M82A1 rifle by 1986.

The first conventional military success was the sale of about 100 M82A1 rifles to the Swedish Army in 1989. Major success followed in 1990, when the US Military purchased significant numbers of the M82A1 during operations Desert Shield and Desert Storm in Kuwait and Iraq. About 125 rifles were initially bought by the US Marine Corps, and orders from US Army and Air Force soon followed. The M82A1 is known by the US Military as the SASR — "Special Applications Scoped Rifle", and it was and still is used as an anti-matériel weapon and EOD (explosive ordnance disposal) tool. The long effective range, over 1500 m with a record shot of 2500 m along with high energy and availability of highly effective ammunition such as API and Raufoss Mk 211, allows for effective operations against targets like radar cabins, trucks, parked aircraft and so on. The M82 can also be used to defeat human targets from standoff range or when targets are behind cover. However anti-personnel work is not a major application for the M82 (or any other .50 BMG rifle, for that matter). There is a widespread misconception that a number of treaties have banned use of the .50 BMG against human targets, and recruits have been advised by generations of drill instructors to only aim a .50 BMG at an enemy soldier's web gear or other equipment worn on his body. However, the U.S. Army Judge Advocate General's office has issued a legal opinion that the .50 BMG and even the Raufoss Mk 211 round are legal for use against enemy personnel.













Further development led to the M82A2 bullpup rifle in 1987, which was a reduced-recoil design to be fired from the shoulder. It failed to make an impression on the world firearms market, and was soon dropped from production. However, in 2006, Barrett had developed the XM500, with a bullpup configuration similar to the M82A2.

M107, almost identical to the M82A1M/A3.The latest derivative of the M82 family is the M82A1M rifle, adopted by USMC as the M82A3 SASR and bought in large numbers. This rifle differs from M82A1 in that it has a full length Picatinny rail that allows a wide variety of scopes and sighting devices to be mounted on the rifle. Other changes are the addition of a rear monopod, slightly lightened mechanism and detachable bipod and muzzle brake.

Another variant of the original weapon is the M82A1A Special Application Scoped Rifle, an almost identical model but specifically designed to fire the Raufoss Mk 211 Mod 0 round, a type of API (Armour Piercing Incendiary) ammunition.
Barrett M82 rifles were bought by various military and police forces from at least 30 countries, such as Brazil, Belgium, Chile, Denmark, Finland, France, Germany, Greece, Israel, Italy, Jamaica, Indonesia, Mexico, the Netherlands, Norway, the Philippines, Portugal, Saudi Arabia, Spain, Sweden, Turkey, the United Kingdom, the United States and others. The M82 also is widely used for civilian .50 caliber long

- range shooting competitions, being fired accurately out to 1000 yards (900 m) and even further.

Baddest handgun on the planet!

The .50 calibur magnum is the baddest handgun on the planet. Imagine owning this - hand cannon? You got that right - hand cannon!

Here's a review from Popular Machinics:

MODEL 500 S&W MAGNUM REVOLVER
In the 1971 movie "Dirty Harry," actor Clint Eastwood introduced the world to the double-action Smith & Wesson Model 29 .44-cal. Magnum revolver--"the most powerful handgun in the world."

It was a crown S&W wore proudly, albeit briefly.
The rising popularity of handgun hunting for big game (spurred largely by the .44 Magnum itself) prompted the introduction of newer and significantly more powerful revolver cartridges. Many powerful enough that they had to be chambered in single-action handguns because existing double-action designs could not contain the recoil forces and pressures they produced.
Since S&W does not make single-action revolvers, and no double-action frame at its disposal could handle the new loads, S&W was effectively dethroned.

At the 2003 Shooting, Hunting and Outdoor Trade (SHOT) Show, the manufacturer regained its crown. And, most significantly, it did it by introducing a new massive double-action revolver that is chambered for an equally new .50-cal. cartridge.
The S&W X-frame Model 500 is a brawny handgun designed to master the most rigorous hunting fields in the world. It is not a revolver one would, or likely could, tuck into a waistband. In fact, to call it massive is an understatement.

With its 8-3/8-in. barrel, the overall length of the Model 500 is 15 in. and the empty weight is 4.5 pounds. The cylinder alone is almost 2 in. in diameter and approaches 2.25 in. in length. Thumb the cylinder open and five charge holes await. Each is 1/2 in. in diameter, and the .50-cal. cartridges they hold are almost 2 in. long. Load five of them and the total weight of the handgun climbs to 5 pounds.

You don't just casually pick up a Model 500. You have to lift it.
Fire even one of those big cartridges and you'll appreciate why the weight and mass are there.
When the .44 Magnum laid claim to being the most powerful handgun in the world, its standard load produced about 900 ft.-lb. of muzzle energy. Several new loads have since eclipsed that, but the handgun most commonly used by big game hunters is the .454 Casull, which will generate about 1900 ft.-lb.

The 500 S&W Magnum will produce almost 2600 ft.-lb. with its heaviest load, and more powerful loads may well be on the way.
If Dirty Harry felt that the .44 Magnum would make his day, the new 500 S&W Magnum would certainly make his decade. It is the largest double-action revolver available, and there is no production revolver in the world--single or double action--capable of matching, or even approaching, the level of power it produces.

Harnessing that power in a double-action revolver, however, required some departures from traditional designs.
