This is a 10-packMagpul PMAG Gen M3 20-round magazine for AR-10 rifles chambered in 7.62mm/.308 Win

Combining lightweight polymer construction with next-gen manufacturing and a whole host of awesome features, Magpul’s Gen M3 PMAG magazines are some of the most practical, affordable, and reliable combat magazines on the market today.

Weighing in at roughly half the weight of a standard USGI steel magazine, with a projected service life that lasts as long as the rifle’s barrel itself, PMAGs are a durable and flexible addition to any AR-10 owner’s arsenal. Thanks to their enhanced strength and reliability, Magpul’s PMAG magazines consistently exceed military specifications in testing.

With this bundle, you’re getting a full ten (10) Gen M3 20-round PMAG magazines for your DPMS LR/SR-25 -style AR-10 rifle (these magazines are NOT compatible with Armalite AR-10B/Springfield M1A lowers). Features a more compact size, aggressive ribbed and textured gripping surface, stainless steel internal springs, and paint pen dot matrix for easy labelling. Other improved features include a redesigned rear notch, a new overinsertion stop, and a detachable dust cover designed to prevent debris intrusion.
