Microtech Defense Industries (MDI) will be releasing a new entry to the polymer rifle magazine market in the next two months. MDI's parent company is the same Microtech you are probably familiar with as Microtech Knives; the magazines are called ACMs (Advanced Combat Magazines).
The ACMs will be available in both .308/7.62x61 and 5.56mm; apparently the former will be a 25-round capacity and latter in 30- and 40-round capacities. Constructed of an "advanced, impact modified, UV resistant polymer with low deformity properties," they'll be available in 'Smoke Translucent', Matte Black, OD Green or Dark earth.
Features of the ACMs are:
- Corrosion resistant body spring
- Molded ridge to prevent over-travel on mag insertion
- High visibility red follower, described as having a "unique riser to allow for positive contact."
- Aggressive texturing for grip and retention.
