Magnum Research
If you own a Magnum Research Mark XIX Desert Eagle and want to expand its capability, the MR BBL DE MKXIX 6" .44 Magnum WMD conversion barrel with two magazines gives you a genuine alternative to the factory .50AE setup. This isn't a whole new gun—it's a dedicated conversion barrel that lets you swap calibers on the same frame, making it a practical option for shooters who want to run both magnum handgun rounds without buying a second pistol. The 6-inch barrel length maintains the Mark XIX's signature presence while keeping your setup manageable at the bench or range.
The barrel features an integrated muzzle brake design, which helps manage recoil impulse when you're pushing heavy .44 Magnum loads downrange. The white matte distressed finish matches the aesthetic of the Mark XIX while providing a practical, non-reflective surface. The conversion comes complete with two 8-round magazines, so you have capacity out of the box and a backup mag for extended range sessions.
Swapping between .50AE and .44 Magnum on your Mark XIX is straightforward—you're simply changing the barrel and magazine setup. This approach makes sense for hunters and long-range pistol shooters who appreciate the precision platform of the Mark XIX but want caliber flexibility without the expense of a second firearm. Whether you're testing load development, hunting medium game, or just want to experience what .44 Magnum feels like through a semi-custom pistol platform, this conversion barrel delivers genuine functionality.

Yes. The conversion barrel design allows you to swap back to your original .50AE barrel and magazine setup whenever you choose. This is the main advantage of a conversion kit over buying a second pistol.
