MR BBL 50AE 6" Black Integral Brake with 2 Magazines

The Magnum Research .50 AE barrel with integral brake gives you a straightforward way to convert your Mark XIX Desert Eagle from .44 Magnum to .50 Action Express. This is the barrel half of a conversion—a 6-inch tube finished in black with an integrated muzzle brake designed to manage the substantial recoil of the .50 AE cartridge. If you're looking to add caliber versatility to an existing Mark XIX platform without buying an entirely new firearm, this barrel swap does the job. The integral brake is part of the barrel assembly, so there's no separate component to install or adjust.

The kit includes two 7-round magazines chambered in .50 AE, so you'll have ammunition capacity right out of the box. Magazine compatibility matters when you're switching calibers, and these are purpose-built for the .50 AE platform. The 6-inch length keeps the overall profile relatively compact for a Desert Eagle while preserving sight radius and sight mounting options.

This is purpose-built gear for shooters who already own a Mark XIX and want to explore what the .50 AE cartridge can do—whether that's long-range handgun hunting, big-bore precision shooting, or simply experiencing one of the most powerful semi-auto handgun rounds in production. The conversion approach means you're not locked into a single caliber; you can swap back to .44 Magnum with the original barrel when the situation calls for it.

What does the integral brake do?

The integral muzzle brake is part of the barrel and helps reduce recoil impulse when firing .50 AE ammunition, making the handgun more controllable and faster to get back on target between shots.

How many magazines come with this barrel?

Can I use my existing .44 Magnum magazines with this .50 AE barrel?
