Ok, mine came today. Thanks CZCustom for the quick shipping.
Only thing is...I can only get 18 in. These were 16 rnd mec gars that I started with. Am I missing something. I put the little tab over the spring, in the orientation shown on the website picture. It rattles when the mag is empty. This normal? Should I assemble it without this piece? I'm kinda puzzled right now. Uplula time?
