For: Beta Project Magpul AK Series 140rd Mid Capacity AEG Magazine (Waffle/Black)Product Information:
I got one of these a few months ago from another site, glad to see airsoftgi carrying them.
The build quality is fairly good on these mags, they're also transparent enough so you can see how many bbs you have left. The baseplates removable to attach ranger plates, the magazine is quite a big smaller in volume than the regular ak47 magazine, and it fits in a magazine pouch a lot easier.
The internals are also removable via two little arms under the baseplate, then you pull it out the top.
It really does hold 140rds, may hold more after being broken in.
Fits magazine pouches easier, because theres less mag curvature.
Holds 40 more bbs then other ak magazines
Pretty wobbley in my magwell
misfeeds the first 10bbs on mine
Not the strongest plastic out there, but Its strong enough.
