Hello Everyone:
I was wondering if anyone can tell me where I may be able to purchase the firearms identification training aid posted below (sorry it's not the best quality). It is a plastic cartridge case and bullet which show the various markings due to firing - firing pin, breech, extractor, ejector, rifling. I've seen them in training videos, but haven't been able to locate them on the internet. Any guidance on this or a similar training aid would be appeciated. Thanks!

I don't believe they are available for purchase.  However I know we have a few we got from Tom Deeb at Hi-Point Firearms.
