American Gunsmithing Institute Armorer’s Course Video on DVD for Winchester Model 12 Shotguns - Technical Instructions for Disassembly, Cleaning, Reassembly and More

Shipping was quick, the quality of video was better than some I have. Would liked to have seen more on the chamber ring/chamber honing and installation. Not just the tools used to do the job. Other parts were covered pretty well.

I have several of these for different firearms. They are informative but not very well done. Just my opinion.
