"It is a nice mag, love the 850 round capacity. has a slight wobble in my ECHO1 MTC 3, (Which uses M4 mags, so I thought it would be a perfect snug fit since both gun and mag were made by the same people)

Had 1 major problem with it right off. The second time I test fired my gun, (for reference I had shot a less than a quarter of the mags capacity at this point in testing) I noticed the magazine wasn't winding up properly, there was tension on the spring but no bbs were coming up to the top of the feeder. I took the feed mechanism out of the bag and discovered that some bbs had gotten jammed in the feed mechanism.

I have never had this problem with regular M4 high caps, will have to wait and see if the issue repeats itself. If this happens more than just a time or two, the mag won't be worth using as if it happens during a match, 850 rounds do me no good if they won't feed through the mag properly.

"I use two of them in my KWA M16. Best support set up ever. These things fit in it as good as the Kwa mid-caps. Never had an issue. Both of them i have put 20 mags on each so far. If i wind them up enough i can get one heck of a burst out of them. They are kind of expensive, But totally worth the money, Especially if you want to be support but don't wanna spend all the major amounts of money.


Comparability with KWA
850 rds, but can still fit in some m4 pouches
Durability and reliability


Wish it was cheaper so i could buy more.

-doesn't look to awkward in the gun
