I apologize in advance for not having a pic yet, but I'm at work and can't get my phone to successfully send a pic via email to my PC. I picked this up with an AK yesterday and it has no manufacturer on it. It's plastic and says Cal. 7.62x39 on the left side near the floor plate. Both sides have seven raised "pictures" of complete rounds. Floorplate is metal and the follower is plastic. Right side has three small stars near the floorplate.
Mag doesn't seem to be very high quality, as it barely squeezes into the mag well. I didn't bother trying to fire with it. Not a BHO mag.
