Matrix 2000rd LMG Auto Winding Hi-Cap Magazine for M4/M16 Series Airsoft AEG Rifles (Package: Box Mag Only)

"Honestly for the price this actually worked quite nicely. I use a warhead/gate build and it runs every time and feeds well

"FYI it takes x4 AAA batteries not AA as advertised it fits perfectly in my g&g cm16 feeds perfect everything about this mag is great just the batteries issue

"This a great mag. After 10k rounds no jams or failures. I've used it on A&K NS15 M4 stubby and Lancer Tactical LT-33 Nightwing. It fits nicely in both guns. I went full auto on both and I did have to switch to the constant feed setting will on the Lancer because of a few misfires, but it only happened twice and I believe that was because of the angle I was at while the ammo was real low. It's awesome not to reload so much and it helps to set the gun down in the upright position so as to not bump my optics and scratch the sides. Other than the bb's rattle (which isn't bad) it has a near silent motor/winding noise operation. The 4 aaa batteries have lasted so far more than 10k rounds which I feel is astounding. And its not that bulky for 2000 rounds. Great quality, great value, great price. I'm buying another one.
