Product Specifications

The 5.56x45mm NATO PMAG 30 GEN M2 MOE is a lightweight, cost effective, highly reliable magazine for AR/M4 pattern rifles. Magpul’s PMAG features a 30-round magazine with 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.

The 10/30 blocked PMAG has been permanently modified by Ace’s Armory for our customers who live in states with magazine capacity restrictions. The PMAG is new from Magpul Industries and will be shipped in its original wrapper. We have modified the original, 30-round magazine utilizing our proprietary HartBlock magazine blocker, which stops the follower at the precise location required to limit the capacity of the magazine to 10-rounds. After inserting the magazine blocker, the magazine base plate or Ranger Plate (if added to purchase) is permanently affixed to the magazine with industrial grade adhesive. Each magazine is inspected during our quality control process prior to shipping to ensure compliance with state regulations.
