The Magnum Research Desert Eagle Bolt Assembly (brand part no. BOLT4450) is a factory replacement bolt built for Desert Eagle pistols chambered in .44 Magnum and .50 Action Express. As the component that locks the barrel to the slide during firing, the bolt takes the brunt of the Desert Eagle’s gas-operated cycle, and a worn or damaged original will show up as rough cycling or failure to lock up properly. This Magnum Research factory part restores correct fit and function without resorting to aftermarket guesswork.
