The Magpul PMAG GEN M3 20-round magazine delivers reliable feeding for .308 Winchester and 7.62x51mm NATO chambered AR-10 pattern rifles. This polymer magazine addresses common feeding issues found in traditional steel magazines while maintaining the durability demanded by serious shooters.
What Makes This Different
The GEN M3 design incorporates an over-insertion stop and modified internal geometry that ensures consistent cartridge presentation to the chamber. Unlike older polymer magazines that suffered from feed lip cracking, this magazine uses Magpul's proprietary polymer blend tested to withstand over 10,000 loading cycles. The anti-tilt follower and constant-curve body geometry eliminate double-feeds and misfeeds common with standard aluminum magazines.Key Features
