AR-15 / M4 – PMAG 40 GEN M3 – 5.56 NATO / .223 – Black
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Magpul PMAG 40 AR/M4 GEN M3 is a 40-round polymer magazine for AR-15/M4 pattern rifles chambered in 5.56 NATO or .223 Remington. It gives the shooter 10 extra rounds over the standard 30-round format without jumping all the way to drum-mag bulk.
This one is for buyers who want more capacity while still keeping a familiar rifle-magazine footprint. It is not subtle, but it is simpler than a drum and easier to live with for a lot of people.
Fitment
- Fits AR-15 / M4 pattern rifles
- For 5.56 NATO / .223 Remington
- Color: Black
Does NOT fit
- Not intended for 300 Blackout-specific use
- Not a low-profile bench or prone-friendly magazine compared with standard 20- or 30-round magazines
What it does
This gives the shooter extra onboard capacity while staying in a conventional stick-mag format. It cuts down reload frequency without the size and loading procedure of a drum.
Why it’s worth it
The PMAG 40 makes sense for range sessions, training, and setups where the buyer wants more capacity but still wants the simplicity of a standard rifle magazine. It is a niche between a 30 and a drum, and for some buyers that is the sweet spot.
