Description
The MDT AICS polymer magazine brings durability and reliability to your precision rifle setup with a no-nonsense polymer design. Built from high-strength, glass-filled polymer paired with a tempered steel spring, this magazine delivers the performance you'd expect from a precision rifle accessory without unnecessary weight.
Material Quality and Durability
MDT uses a high glass-content polymer formulation throughout this magazine, engineered to handle real-world abuse. The company backs its durability claims with testing that includes driving vehicles over loaded magazines, so you're looking at a magazine that handles impacts and rough handling without failing. The finish resists corrosion and minor dings that would affect feeding.
Chassis and Bottom Metal Compatibility
This magazine is guaranteed to work in MDT's TAC21, ACC, ESS, LSS, LSS-XL, XRS, HS3, and HNT26 chassis systems. Beyond MDT platforms, it's compatible with most M24-pattern AICS bottom metals from other manufacturers, making it a practical choice whether you're running a complete MDT build or retrofitting an existing rifle platform. Precision shooters appreciate the universal AICS format because it gives you options.
Ammunition Compatibility and Feed Reliability
The 5-round magazine chambers 308 Winchester, 6.5 Creedmoor, and other cartridges in the 308 family including 6mm Creedmoor, 243 Winchester, 260 Remington, 7mm-08, and 7.62×51 NATO. The precision-molded feed lips and internal geometry handle each round with care, delivering smooth, consistent feeding every time you run the magazine through your system.

Frequently Asked Questions
Will this AICS magazine work with my chassis system?
The magazine is guaranteed to work with MDT TAC21, ACC, ESS, LSS, LSS-XL, XRS, HS3, and HNT26 chassis systems. It's also compatible with most other M24-pattern AICS bottom metals from aftermarket manufacturers, though some third-party systems may require minor fitting. If you're unsure, check your specific chassis documentation or reach out to the chassis manufacturer.
Can I use this 5-round magazine for calibers other than 308 and 6.5 Creedmoor?
Yes, the magazine works with multiple cartridges in the 308 family including 6mm Creedmoor, 243 Winchester, 260 Remington, 7mm-08, and 7.62×51 NATO at full capacity. You can also load 22-250 Rem, but expect reduced capacity. The magazine is not recommended for 300 WSM, which works better with MDT metal magazines.
How durable is the polymer compared to a steel magazine?
MDT's polymer construction includes high glass content for strength and has proven durable through rigorous testing, including vehicle impact tests. Compared to steel, the polymer is lighter and naturally resists corrosion better. Some users prefer polymer magazines for quieter operation and better feeding, though steel magazines offer maximum longevity in extreme conditions.
What's included when I order this magazine?
