Magpul’s PMAG 20 LR/SR GEN M3 Magazines are a perfect addition to any AR10, M110, or SR25 setup. This 20-round magazine is compatible with 7.62x51 NATO/.308 Win, and features a crush-resistant polymer body which is less than half the weight of its standard issue steel counterpart. To ensure the utmost reliability, the PMAG 20 LR/SR GEN M3 Magazine utilizes and anti-tilt follower with self-lubricating properties, a high-quality stainless steel spring, and a constant-curve internal geometry for smooth feeding. This combination of a durable polymer body and optimized internal components gives the PMAG 20 LR/SR GEN M3 Magazine a service life roughly equivalent to the service life of the rifle’s barrel. Other features of the PMAG 20 LR/SR GEN M3 Magazine includes an easy-to-disassemble floor plate to make maintenance simple, and the included pop-off impact/dust cover minimizes the chance of debris entering the magazine as well as preventing damage to the top cartridge during storage/transit. In addition, the PMAG 20 LR/SR GEN M3 Magazine features a paint pen dot matrix for easy identification-marking by the end user.
