This thing is awesome it uses standard AA batteries is real metal. It locks into place and doesn't move around. Feeds like a champ.

Great design except for the fact the feed spring is hard to set AFTER the bb's are loaded and it takes AA batteries not AAA batteries like the description states.

i have never had a problem with this gon

This clip is amazing whenever your airsofting and you never run out of ammo. I used this clip in my cyma rpk and it fits good, i highly recommend buying this. It is mad out of good metal and winds really fast with a push of a button. This mag takes 3 AA batteries.

Hyper space shipping. I tried this drum in my CYMA RPK, Dboys AK74U, Cybergun AK74U and a CYMA full size AK74. Fits them all and works like a drum should. Keep it wound with a short push of the button and hold the trigger. Time to invest in bulk ammo..... Great price from the Rattle too!
