Description
MDT engineered this metal magazine to handle the demands of modern magnum cartridges without compromising on size or durability. The 3-round capacity makes it ideal for precision work where you're placing every shot carefully, whether hunting or range shooting. What sets this magazine apart is the Double Stack to Single Feed (DSSF) transition design that keeps the overall profile compact compared to traditional short-action magnum magazines.
Construction and Durability
Built from high-strength steel with a nitrided finish, this magazine gets coated inside and out with Cerakote Elite for serious corrosion resistance and friction reduction. The result is a magazine that feeds smoothly and stays reliable in field conditions. The black Cerakote Elite finish handles weather and wear without requiring much maintenance.
Compatibility and Fit
This magazine works with all AICS-pattern bottom metal and chassis systems. It accommodates cartridges up to 2.960" overall length, giving you flexibility with different bullet profiles and loads. Compatible with 6.5 PRC, .300 WSM, .270 WSM, and 7 RSAUM. The magazine comes without front binder plates for a cleaner fit. Most common actions like Remington 700 and Savage 10/11 may need receiver modifications to prevent bullet tips from contacting the feed ramp, something to verify before installation.
Real-World Performance
Users report smooth feeding and solid construction quality across various platforms. The metal magazine approach gives you the durability needed for repeated use, and the compact footprint makes sense if you're running a tight setup or dealing with space constraints in certain chassis designs.

Frequently Asked Questions
Will this magazine fit my Remington 700 or Savage action?
Yes, it's compatible with AICS-pattern bottom metal on these actions. However, most Remington 700 and Savage 10/11 receivers need the feed ramp notched out to prevent bullet tips from catching during feeding. Check with your gunsmith or chassis manufacturer before installation to confirm fitment with your specific setup.
What cartridges does this magazine work with?
This magazine is designed for 6.5 PRC, .300 WSM, .270 WSM, and 7 RSAUM. It accommodates cartridges up to 2.960" overall length, so you'll want to verify your specific load combinations fit within that window.
How does the DSSF design benefit this magazine?
The Double Stack to Single Feed transition means the magazine can nest rounds more efficiently, resulting in a lower overall height compared to conventional short-action magnum magazines. This keeps your rifle's profile compact, which matters in chassis systems where space is tight.
Why is this steel magazine nitrided and coated with Cerakote Elite?
The nitrided steel base gives the magazine structural durability, and the Cerakote Elite finish adds corrosion resistance and reduces friction for smoother feeding. This two-part approach ensures the magazine performs reliably in wet conditions and maintains smooth operation over extended use.
