This is an unused Circle 10 drum magazine. I believe it is a 75 round magazine. This is a pre-ban Chinese mag. It's for a collector, but is still shootable. There are cheaper mags out there. If you just want a shooter drum for your AK and don't care what it is, go and find one of those. 

Meet near Cabela's in Glendale. 

Not interested in trades anything other than cash.

Selling for $250. Compare the price to the drum in the screenshot that is missing the follower - they want $300 for that one.
