The Desert Eagle was originally designed by Bernard C. White of Magnum Research, who has filed a U.S. patent for a mechanism for a gas-actuated pistol in January 1983. This established the basic pattern of the Desert Eagle. The Desert Eagle was originally designed as a revolver, but was later redesigned into a semi-automatic pistol. A second patent application was filed in December 1985, after the basic design has been refined by IMI for production, and is the form that came into production.
The Desert Eagle uses a gas-operated mechanism normally found in rifles, as opposed to the short recoil or blow-back designs most commonly seen in semi-automatic pistols. Unlike most guns, the barrel does not move during firing. When a round is fired, the gases are carried through a small hole in the barrel near the breech. These trips to the front in a small tube under the barrel, a cylinder in front of the barrel. Separate the carrier bolt / slide has a small piston in the front which is part of the cylinder when the gas reaching the cylinder, they push back the piston. The bolt carrier rides backwards on two rails on each side of the gun, the operating mechanism. Its twist lock is very similar to that of the M16 series of rifles, while the gas
cylinder fixed / moving piston resemble those of the Ruger Mini-14 carbine (the original patent used a captive piston similar to the M14 rifle). The advantage of gas-operation is that it allows the use of more powerful cartridges than traditional semi-automatic pistol designs. Thus, it allows the Desert Eagle to compete in an area that had been dominated by Magnum revolvers. Disadvantages of gas operated mechanism are the large size of the Desert Eagle, and the fact that it discourages the use of lead bullets uncoated, as lead particles sheared off during firing could clog the gas release valve, preventing the operation.
Switching a Desert Eagle to another chambering requires only that the correct barrel, bolt assembly, and the magazine will be installed. Thus, a conversion to fire cartridges other can be quickly accomplished. Barrel length is the most popular 6-inch (152 mm), while a barrel of 10 inches (254 mm) is available. The Mark XIX barrels are machined with integral scope mounting bases, simplifying the process of adding a field gun. The rim diameter of 0.50 AE is the same as .44 Remington Magnum cartridge, so that the barrel and magazine change is required to convert a 0.44 Desert Eagle to the largest, most powerful AE 0.50.
According to customer specifications, the overall color and finish of an eagle can vary considerably. Standard offer factory is entirely matte black. If you plan to shoot the gun a lot, then the matte black factory may be the best choice, since any wear, dents or dings just add to its overall impression of "work horse" efficiency.
If you want a little more direction, or if you live in a maritime environment with moisture aids, one of the hard chrome finishes - either polished or satin nickel - might be better. Magnum Research Custom Shop also offers options in titanium and 24 karat gold. The gun is also available in a polished deep blue.
The current Eagle is the Mark XIX. One of its best features is the interchangeability of the barrels on the same chassis - not just barrels of different lengths, but also barrels of different calibres. Calibers .50 AE, .44 Mag. 0440 and Cor-Bon all use cartridge cases with the rim of the same size, so they can all use the same bolt. Pop off one barrel, pop on the other, and you're ready to fire.
You can also install a Mag 0357. barrel, but this requires a change of bolt to accommodate the smaller rim. Not a big problem, but not quite the change in caliber of five seconds you can achieve with others. [A change magazine is also necessary that you switch templates, except in the case of conversion between 0.50 and 0.440 EA Cor-Bon, which both use the same magazine.] A word of caution though - the brand part XIX should be used with new Mark XIX barrels. Do not install barrels from a Desert Eagle more.
The secret to using the same framework for different caliber barrels is the size of the hole gas in the barrel, which regulates propellant gases used to cycle the gun. Genrerated gas when the cartridge is from the flow through the port and along a channel under the barrel. At the end of the string, it pushes against a small piston attached to the blade and drives backward slide. As the blade begins to move (this does not occur until the ball has opened his mouth), the bolt rotates, unlocks and moves rearward, ejecting the empty shell.
When the blade begins to move forward, the bolt back a new round of review and it pushes forward into the room. At the end of its forward movement, the bolt rotates and locks behind the chambered round. Presto, ready to fire again!
