I plant my magazine on the deck as often as possible in order to get as stable as possible when shooting from the prone position. Standard 20 round 7.62 NATO magazines are just too short for this technique. 25 round magazines, however, work well but, unfortunately, there really aren’t many 25 round 7.62 magazines available.
Microtech Defense Industries is on the verge of releasing their ACM 7.62-25 Magazine. This polymer, SR-25 pattern magazine features a 25 round capacity, aggressive texturing, a corrosion resistant spring, over-travel prevention ridge, and a high visibility follower. More and more 7.62 chambered ARs are utilizing the SR-25 pattern magazine so it is exciting to see a product like this coming to market.
