Magpul 20-Round PMAG Overview


The 20 round PMAG from Magpul offer a great medium range capacity magazine for the AR-15 rifle and other compatible platforms.  The low profile 20 round AR-15 magazine is perfect for shoot off a bipod, backpack or shooting rest, when a longer magazine would get the in way.  Also, this high clearance profile of the 20 round mag can be helpful if you store you firearm with magazine in it for defensive purposes, such as in your back of your truck or in a convenient place for home protection.


The new Gen M3 magazines are formed from a break-through, next-generation polymer that offers amazing crush resistance and durability.  During their development, the M3 Magpul PMAGs were subject to rigorous testing.  This included Feed-Lip drop tests, side impact tests, crush tests, heat and pressure tests, and many others.   Just check out the video below…



Although the M2 PMAGs were an excellent choice in magazine (and still are) due to minor design features of their internal and external geometry, they were not as widely compatible as the standard USGI magazines.  However, with an updated design, this 20 round M3 PMAG is compatible with a much wider variety of firearms.  Specifically, the M3 PMAGs can now function reliably in the FN SCAR, HK 416, the British SA-80, as well as many other platforms.  


There is a long list of the updates going from the M2 to the M3 PMAG.  Additionally, the M3 PMAGs include a dust/impact cover at no additional cost.  If you are looking for a top quality magazine at at very competitive price, look no further.  You’ve found it.
