Description
The PMAG 20 AR/M4 GEN M3 delivers a compact 20-round profile with the same proven feeding geometry, anti-tilt follower, and crush-resistant polymer as the rest of the GEN M3 family. Ideal when you want a shorter magazine without sacrificing reliability—built to feed smoothly, survive hard use, and perform when it matters most.
It features
- Constant-curve internal geometry and self-lubricating anti-tilt follower keep rounds cycling smoothly in any condition
- Crush-resistant polymer body withstands impacts, drops, and pressure without cracking or splitting
- Reinforced feed lips and over-insertion stop deliver reliable function across M4, M16, AR15, HK® 416/MR556, M27 IAR, and other platforms
- Aggressive texturing for positive control, paint-pen panels for quick ID, and a removable floorplate for easy cleaning
- Flared floorplate aids magazine handling and disassembly, and is slim enough for use with many double and triple pouches
This magazine has been tested in extreme heat, cold, mud, and sand to guarantee performance when it matters most and is a magazine that we trust here at Mountain Man Defense. Get yours today!
