Magpul PMAG AR-15 Magazine, 30 round AR15. *Military discounts available. The Magpul PMAG 30 round magazine is a lightweight 5.56 NATO, AR-15, M-16 compatible magazine. It features a 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. PMAGs utilize a resilient stainless steel spring for corrosion resistance. The Magpul Polymer PMAG Magazine fits the AR-15/M-16 series and other 5.56x45 NATO compatibleweapons. It features numerous enhancements intended to improve reliability, long-term storage, overall durability and is designed to fit 30 rounds without any need for downloading. Loaded PMAGs insert and lock easily in a closed bolt weapon or may be stored for extended periods with the unique Impact Cover in place. They also feature a special anti-tilt follower that prevents binding and improves feeding consistency. The Impact Cover snaps firmly onto the top of the PMAG via interlocking tabs (unlike aftermarket dust covers) and can be quickly removed with one hand. Fitted into place, the Impact Cover provides impact protection for the feed lips, prevents dirt/dust intrusion, and eliminates distortion of the feed lips caused by long-term loaded storage. When separated, the Impact Cover serves as a magazine tool that facilitates unloading and disassembly. A lanyard hole is included to prevent part loss. The proprietary Anti-Tilt Follower works in conjunction with the magazine body to stabilize the loaded round stack. The magazine body features a constant internal curve (unlike metal magazines with a curveto- straight transition) and allows for consistent round stack regardless of round count. This configuration prevents many of the common feeding malfunctions seen in other magazines such as nose-diving and bolt-over head failures. Features • Constant-curve internal geometry for smooth feeding • Anti-tilt, self-lubricating follower for increased reliability • Storage/dust cover • Stainless steel spring for corrosion resistance • Textured gripping surface
