Two things on the rotary mags, first there are several good videos out there showing how to disassemble them and reassemble them for a good cleaning should the time come. Second thing I would like to pass on for any of you hunting with either a 10/22 or 77/22 and using the standard 10 round mags, I have found that those mags ride very well in speed loader holsters. Real handy in the woods.
