Kinda less point if it's not auto ...
What would be
really good would be if I could find a nato 308 conversion kit for my yugo M53 (and to convince my wife that I should keep the thing, and not sell it as the "investment" I touted it as part of talking her into it in the first place
).
I have almost everything required to convert to a blank-firing Smartgun but, feeding it 8mm Mauser is too hard (as we'd have to hand make each blank by cutting down a something with a longer case. Boo to that!).
One day I'll sort it out, just not anytime soon, sadly.
