The Best AR-15 Magazine, Extended
The Magpul PMAG 40 Gen M3 magazine is a 40-round 5.56x45mm NATO (or .223 Remington) polymer magazine for AR-15/M4 compatible weapons. This PMAG AR-15 magazine provides extra firepower over standard magazine size and functions flawlessly every time, no matter what conditions you encounter. Along with an expanded feature set and compatibility, this PMAG 40 magazine incorporates new material technology and manufacturing processes for enhanced strength, durability and reliability to exceed rigorous military performance specifications. 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.

Good fit
The 40’s are great, good fit on the weapon (M-4). I wanted to purchase 2 40 round clips in case I ever have to get the party started and then fall back on my other 7 -30 round clips to close the nights festivities should I ever need to go to a party like that.

Great quality with a great price!
Really liked the clip on cap that helps with not jostling rounds out when traversing through obstacles.
