I bought this magazine to go with my new Umarex H&K G36C blowback, so I would have two. It looks and functions exectly like one that came with my gun, so It clips together with the other mag easily and securely. Made of plastic, but very solid, much like the gun itself. I watched the GITV video about G36 mags,so I tested how many rounds I could get out of one full wind, and after about 30 seconds of winding I fired 208 rounds on full auto until no more bbs fed. So, if you wind correctly, you should only have to wind three times per mag perhaps two. If you want a mag that is as good as or better than your stock mag, buy this mag.
The best high cap G36C mag hands down
clips perfectly with my Umarex mags
It isn't see through which I like, I think see through looks stupid without real bullets
200+ shots per full wind of the wheel
Price, but that's it.
