Feeding a long-action magnum reliably is where cheap magazines fall apart, and this is exactly where MDT built its reputation. This is the 5-round metal AICS-pattern magazine chambered for .300 Winchester Magnum, made from high-strength steel and finished in Cerakote Elite for durability and corrosion resistance that holds up in the field. If you run an AICS-pattern chassis or DBM bottom metal and need dependable magnum feeding, this drops right in and gets to work.
This is the 3.850" CIP length version, which means it's cut for rifles and chassis with a longer CIP-spec magazine well and gives you room for full magnum cartridge overall lengths. Worth noting: most MDT chassis ship with a 3.715" well, so double check your setup before ordering. If your rifle or chassis is spec'd for the longer 3.850" mag, this is the one you want. The steel spring and follower keep rounds stacking and feeding the way they should, shot after shot.
It works with AICS-pattern DBM chassis and bottom metals, so it plays nice with the popular platforms built around that standard. One handy bonus with the .300 Win Mag body is that it can also run 7mm Rem Mag, 30-06, 6.5×55 and similar cartridges by adjusting the feed lips, which makes it a flexible option if you shoot more than one long-action round. The capacity is rated at 5 rounds based on magnum cartridges.
MDT backs these metal magazines hard because they're built to last. The nitride and Cerakote treatment shrugs off the kind of abuse a hunting or precision rifle sees, and the removable floor plate makes cleaning and spring maintenance quick when the time comes. For anyone running a serious .300 Win Mag, this is the kind of magazine you buy once and forget about.
It's compatible with AICS-pattern DBM chassis and bottom metals, so it works with the common platforms built to that standard. The catch is length: this is the 3.850" CIP version, while most MDT chassis use a 3.715" magazine well. Check your rifle or chassis spec before ordering to make sure it's cut for the longer CIP magazine.
The number refers to the overall magazine length and the corresponding magazine well it fits. This 3.850" CIP mag is built for CIP-spec chassis and bottom metal and handles a longer maximum cartridge overall length of about 3.760". If your setup calls for the standard 3.715" mag, that's a different part, so match the length to your well.
Yes. The .300 Win Mag body can also feed 7mm Rem Mag, 30-06, 6.5×55 and similar cartridges by adjusting the feed lips. That makes it a versatile choice if you shoot more than one long-action round, though the rated 5-round capacity is based on magnum cartridges.
This one is all metal, built from high-strength steel and finished with Cerakote Elite for corrosion resistance and long-term durability. It uses a steel spring and follower for consistent feeding, and the removable floor plate lets you break it down for cleaning and spring maintenance.
