Matrix Bulgarian Waffle Type 550rd Hi-Cap Magazine for AK Series Airsoft AEG (Color: Dark Earth)

"Okay, so this mag is really well built externally and feels sturdy, but I found an issue. As some of the other reviews mentioned, the bbs wouldn't feed and would get stuck. This happened to me about an hour before a game, so I was quite upset. A day later I realized something, if I lubricated the feeding wheel and the winding wheel it should all be slick and maybe the bb that gets stuck can pop out. I was correct, to avoid jams I suggest regularly lubricating this magazine. Aside from that, the only other problem I found is the lip on the back of the mag is a bit low for some aks, so have have to seriously jam it in (for example, LCT LCK-15 and JG AKS-74u EBB). Aside from those minor issues, this is a great mag that feeds very well, I owned one previously that came with an AK, and the only reason it didn't last longer than 3 years was because I dropped the whole AK stock first onto concrete with the mag still inside, causing the front lip to crack and eventually (3 years later) break.

Pros:
Great feeding
Sturdy Build
Cheap

Cons:
Regular upkeep
Doesn't fit easily into some AKs (still fits though)

Personally I think this should be 4 and a half stars for regular upkeep, but the jamming issue is so easy to solve, it doesn't seem worth 4 stars.

"I bought this along with a CYMA AK74 (cm040c). Out of the box, it doesn't fit. The top of the mag needs a bit of sanding/filing as the plastic sticks out too far and is larger than the mag well. But a few minutes with a file and sandpaper and it works. Fits nice and tight, no wobble (unlike the mag that came with the gun). I'll be grabbing another one with my next order.

"the fit was wicked loose (1/4" wobble in both directions when seated in the mag well), but with some thin plastic card, super glue, and a fine file, this mag fits even better than my gun's factory mag. I guess making it to fit more universally could create this issue in some models.
