Magpul PMag 40-Round Magazine for AR-15

Features

1. 40-Round Capacity — Extended 40-round 5.56x45mm NATO (.223 Remington) capacity puts ten extra rounds on tap over a standard 30-round mag.
2. GEN M3 Construction — Next-generation impact and crush-resistant polymer body stands up to hard field use, drops, and rough handling.
3. Broad Platform Compatibility — Optimized for Colt-spec AR-15/M4 receivers, with modified internal and external geometry that also permits use in HK416, M27, SCAR MK16/16S, MR556A1, and other compatible platforms.
4. Constant-Curve Geometry — Smooth internal curve combined with a self-lubricating, four-way anti-tilt follower delivers reliable feeding round after round.
5. Reinforced Feed Lips — Beefed-up feed lips and an over-insertion stop protect against damage during hard reloads on a closed bolt.
6. USGI-Spec Stainless Steel Spring — Corrosion-resistant stainless internal spring maintains consistent tension through long storage and high round counts.
7. Aggressive Texturing — Low-profile ribs paired with new front and rear texturing give a positive grip during fast mag changes in any environment.
8. Paint Pen Dot Matrix — Molded dot matrix on the bottom panel lets you mark and identify individual magazines without ambiguity.
9. Flared Floorplate — Slim-line floorplate aids extraction from mag pouches yet provides positive control on insertion and removal.
10. Tool-Free Disassembly — Breaks down quickly for cleaning and inspection with no special tools required.
