Review for
Magpul Industries PMAG GEN M3 AR-15/M16/M4 .223 Rem/5.56x45mm NATO 20 Round Rifle Magazine
The Magpul PMAG 20-round magazine is one of the best-balanced AR magazines available. It keeps the rifle compact and lighter than a 30-round mag, making it much more comfortable for bench shooting, prone positions, hunting, storage, and carrying in vehicles or packs. At the same time, it still provides enough capacity to avoid constant reloads like with 10-round magazines.
Like other PMAGs, reliability is excellent — durable polymer construction, smooth feeding, anti-tilt follower, and proven performance under hard use. The 20-round size simply gives the rifle a cleaner handling profile without sacrificing practicality.

optimized reliability

Excellent magazine for .300 Blackout platforms. The dedicated Magpul PMAG 300 BLK magazine feeds subsonic and supersonic rounds much more reliably than standard 5.56 mags, especially with heavier bullet profiles. The internal geometry is optimized for the different cartridge shape of .300 BLK, helping prevent binding, nose-dives, and feeding inconsistencies that can sometimes happen when using regular 5.56 magazines. Durable, lightweight, and dependable — exactly what you expect from Magpul.

Functions like Vortex and other scopes.
Holds Zero well with my AR-15 rifle.
Clear image and great eye relief
Easy to adjust (no tool needed) - just pull knob and adjust, then push back to secure/lock in place.
Comes with a killflash and scope flip covers.
