Thanks guys!
It is missing the stacking swivel and screw, hand guard, safety, and the extractor pin. The magazine cutoff is non-functional, will probably have to replace that. I'll have to remove the butt plate to open the trap door, not sure if that will need a spring replacement or not. I'm guessing the cleaning kit is gone, but won't know til I get the butt place off.
Once I get it to the point I can safely shoot it, I'll figure out how far I want to go replacing parts.
