Introduced in 1996. This new design is manufactured in U.S. and allows interchangeability of barrels to switch calibers between the same receiver. Single receiver can be turned into six different pistols in three Magnum calibers. Available are .50 A.E., .44 Magnum and .357 Magnum in barrel lengths of 6" or 10". Separate magazines are also required. Eight different finishes offered as well. Separate bolt assembly is necessary to convert .44/.50 calibers to .357. There are so many different possibilities with this design that only basic pistol prices are given. Extra barrel assemblies are an additional cost. Some models have under barrel Picatinny rails as well as Weaver scope rail. NOTE: Custom shop finishes for Desert Eagle pistols are available in satin nickel, bright nickel, polished and deep blued, case hardened, matte hard chrome, polished hard chrome, brushed hard chrome, titanium gold, and gold with tiger stripes. All finishes beyond basic matte black add $100 to $200 to the base price of pistol; add $400 for gold; add $600 for case hardened or gold/tiger stripe finish.
