I got a Auto Drum with my LCT. Today I was setting it up. For the longest time I couldn't figure out it worked. I could not activate the powder drop. I even crushed a case. Finally, as I was tearing it apart, a black plastic ring fell out at the bottom. It had a tab on one side that was grooved to fit into the cut out on one side. It was my problem. It was preventing the spring from compressing. After that, it worked great. I looked at the instructions again and never saw anything about that piece. None of the pictures I saw in the paper or online, never even showed that. My question, am I and idiot and miss something or what that something used in the assembly that should have been taken out before it was packaged?
