Description
The MDT AICS Magazine for .300 Winchester Magnum delivers the durability and reliability you need in a precision rifle setup. Manufactured from high-strength steel and finished with Cerakote Elite, this magazine resists corrosion and maintains smooth operation through seasons of use at the range or in the field.
What Makes This 5-Round AICS Magazine Work
This magazine is designed specifically for the 3.560" long-action dimension, which fits rifles like Tikka T3/T3x and Savage Axis builds running magnum cartridges. The steel construction paired with a removable polymer follower gives you both durability and easy maintenance. A steel spring ensures consistent feeding even when you're running full or partial loads.
Built for Magnum Performance
The 5-round capacity makes sense for .300 Winchester Magnum, where each round takes up more room than standard cartridges. You get a magazine that sits low and snag-free, which matters whether you're shooting prone or moving through challenging terrain. The design supports smooth, quiet insertions without compromising feed reliability.
Compatible with Your AICS Setup
This magazine works with any rifle sporting AICS-pattern detachable box magazine (DBM) chassis or bottom metals that accept the 3.560" magazine length. Whether you've built a custom rifle or run an off-the-shelf platform, compatibility is straightforward as long as your magwell follows AICS specifications.
