Magnum Research BOLT4450 .44 Magnum / .50 AE Bolt Assembly - Desert Eagle Mark XIX

The Magnum Research BOLT4450 is the factory bolt assembly for the Desert Eagle Mark XIX pistol chambered in .44 Magnum or .50 AE. This genuine replacement bolt is required when converting a Mark XIX up from .357 Magnum to the larger calibers, paired with the matching barrel and magazine for that caliber.

The bolt drives the Desert Eagle's distinctive gas-operated, semi-automatic action, locking the multi-lug rotating bolt head into the barrel's integrated breech. Magnum Research machines the BOLT4450 to original factory specifications for a precise fit and reliable cycling. It is finished in black to match the standard Mark XIX bolt appearance and ships as a single factory replacement assembly.

Use this bolt assembly as part of a caliber conversion on your Mark XIX or as a direct replacement during a rebuild. Caliber compatibility: .44 Magnum and .50 AE.
