Magnum Research was incoporated in 1979 for the purpose of creating a Magnum chambered semi-automatic pistol. This pistol would come to be known as the Desert Eagle. The main problem that had plagued development of Magnum semi_autos was their difficulty to cleanly cycle. Which led the management to outsource to IMI(Israel Military Industries) to help design a gas operated rotating-lug to cycle the weapon. Other innovations from Magnum Research include: Easy barrel swapping and the .50AE cartridge. Currently, the Desert Eagle is manufactured by the IMI and imported into America by Magnum Research. Other Magnum Research products include: Baby Eagle, Lone Eagle and the BFR(Biggest Finest Revolver).
