The PMAG 30 AR/M4 GEN M2 MOE is a 30-round 5.56x45 NATO (.223 Remington) AR15/M4 compatible magazine that offers a cost competitive upgrade from the aluminum USGI.
It features an impact resistant polymer construction, easy to disassemble design with a flared floorplate for positive magazine extraction, resilient stainless steel spring for corrosion resistance, and an anti-tilt, self-lubricating follower for increased reliability. Magpul Original Equipment (MOE) is a line of firearm accessories designed to provide a high-quality, economical alternative to standard weapon parts. The MOE line distinguishes itself with a simplified feature set, but maintains Magpul engineering and material quality. The GEN M2 MOE is identical in form and function to the older model PMAG except that the optional Impact/Dust Cover is now sold separately. Made in U.S.A.
