Magnum Research Bolt Assembly Features The Magnum Research Bolt Assembly is designed specifically for the Desert Eagle Mark XIX platform giving owners a factory correct replacement part for caliber conversion work. Chambered for .44 Magnum and 50 AE it is used alongside a matching barrel and magazine to convert a .357 Magnum Desert Eagle into one of these harder hitting cartridges. Because it is built to Magnum Research s own specifications the bolt assembly maintains the reliability and timing the Desert Eagle is known for. This makes it a straightforward path for an existing owner to add versatility to a pistol they already trust. Finished in black to match the rest of the Desert Eagle s controls and furniture this bolt assembly keeps a converted pistol looking factory original rather than mismatched. Installing it alongside the correct barrel and magazine is the standard method Magnum Research designed for caliber swaps on this platform. Desert Eagle owners who want to shoot .44 Magnum or 50 AE without purchasing an entirely new firearm will find this assembly a practical cost effective option. For sale at GrabAGun it is a genuine part for expanding what a Mark XIX Desert Eagle can do.
