Tuning FX Crown MKII 22 Cal, Magazine

I just had the same thing happen to both mine. Take them apart, clean them very well, use the smallest amount of lube on the center post, and on the inside of the mag where it rotates on the center post. When you put them together I think I wound mine 4 times, re assemble them and play with the screw tension in the center. A bit of fiddling and they work out.
