Magpul PMAG Gen-M3 30-Round Magazine AR-15, .223/5.56, MAG557-BLK. These are great mags!

The next-generation PMAG 30 GEN M3 is a 30-round 5.56x45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons. It features an anti-tilt self lubricating follower, and a constant-curve internal geometry for smooth feeding. It also features a pop-off impact/dust cover, and flared floor plates to aid in magazine handling and disassembly. Ribbed gripping surfaces and aggressive front and rear texture impact positive magazine handling, and paint pen dot matrix panels on the bottom of the body of the magazine allows for identification marking.

Similar to the MOE PMAG, the GEN M3 features a long-life stainless steel spring, four-way anti-tilt follower and constant-curve internal geometry for reliable feeding. It also features simple tool-less dissassembly for easy cleaning. With low profile ribs and new aggressive front and rear texture gives positive control of the GEN M3 in all environments.

It is not compatiable with the Gen M2 Ranger Floor Plates. 

Magpul appeared out of nowhere a few years back and quickly became the industry standard bearer in AR-15 mags and related accessories.  Now their products are considered among the best in the industry.

You can buy more expensive mags, but you can't buy them any better.
