Cargador 130bb de polímero reforzado AK47 - Negro [CYMA]

This is by far the best polymer magazine I'd ever touch. The feeling is much better than the cheap mags most AKs come with. The feed is good, I didn't have any issues with G&G BBs. It comes with some instructions on the backside of the wrapping if you don't know how to maintain it.

Having used the Cyma AK47 Reinforced Polymer Magazine with my Cyma 037 on two occasions without any trouble, I am pleased to share my thoughts on its performance and build quality. The magazine is available in two colours: black and dark earth as well. The reinforced polymer material is impressively durable, capable of withstanding the usual bumps and drops during gameplay. It has shown no signs of wear after my initial uses. In both sessions, the magazine fed flawlessly without any jams or misfeeds. This consistent performance is crucial during intense airsoft matches. Never forget: Mid-cap magazines must be prepared in a particular way before the first usage!

Recently bought a couple of these magazines for use in shooting ranges etc.
So far they are high quality magazines with a strong spring. I have had 0 feeding issues so far and have put about 1000 BB's through them.
Although they are on the cheap side, I would highly recommend the 500 round high cap version of this magazine if you intend to use it on a field.
Definitely need a speed loader to efficiently load these magazines.

They feel sturdy and durable, and have some heft to them.
The matte finish allows for a good grip! :)
Super satisfied with them.
No issues with misfeeding or the like.
The magazines my LCT AKS74UN perfectly.
