The PMAG 10 GEN M3 is a 10-round 5.56 NATO polymer magazine for AR-15/M4 compatible weapons. This magazine features a long-life USGI-SPEC stainless steel spring, four-way anti-tilt follower and constant curve internal geometry for reliable feeding. A redesigned bolt catch notch in the rear of the magazine provides increased bolt catch clearance, while an over-travel stop on the spine helps ensure the magazine will not over-insert on compatible weapons.

Slim, for better compatibility with tight magazine pouches, this easy to disassemble AR mag features a flared floorplate, low profile ribs, and aggressively textured front and rear surfaces for positive control. A paint pen dot matrix on the bottom panel of the body allows easy marking for identification.

For the product its magpul so there isn't much to say about it :-)But for the store, PA is local to me and my goto LGS for most of my stuff, nice bunch of guys, hopefully they will carry some Tavor in the future.



A mag is a mag. This mag is affordable and worth buying a couple.

I have not had a bad magpul magazine.





all went well. this place rocks...fastg shipping.

Another Great Purchase!


Another purchase that went without a flaw, Great price and super fast shipping. Primary Arms is my 'go to' firearms folks!

Just like the rest of the Magpul line...


As I've come to expect from all Magpul products, these mags are rock-solid. And they fill in a niche that shooters in capacity capped states needed. Now that CO has joined that nefarious list, it's good to have a handful to take to the range... or anywhere else (like Denver) that mag size is capped.The purchase experience with PA was excellent also. I'll definitely be doing business with both Magpul and Primary Arms again.
