The PMAG™ (Polymer MAGazine) is a lightweight 20-round 5.56 NATO, M-16 compatible magazine. This PMAG™ features a straight body and pop-off storage/dust cover that alleviates pressure from the magazine feed lips, allowing for long-term storage of loaded magazines without risk of feed lip creep that often causes malfunction in standard aluminum magazines. PMAG™ utilizes a resilient stainless steel spring for corrosion resistance and a controlled-tilt, self-lubricating follower for increased reliability.
