The Magnum Research Desert Eagle .44 Magnum 6-inch conversion barrel (brand part number BMCP446CH) lets a Mark XIX Desert Eagle owner add a second caliber to an existing frame without buying a whole new pistol. The kit swaps a .50 AE Desert Eagle over to .44 Magnum in minutes, no gunsmithing required, and includes everything needed to make the switch. This is the classic Desert Eagle appeal: one iconic gas-operated frame, multiple hard-hitting magnum calibers, and a case hardened finish that gives the barrel a distinct two-tone look next to a black frame.
