$60 G&G M4 CM full metal bone yard. Thank you GI Tactical. It was not broken: it just needed to be gone over. Things that were wrong- 1) the fuse was missing and the container for it cracked. Replaced 2) Barrel nut needed to be tightened. Fixt 3) Mag well is tight on plastic mags. Fixt 4) Stock is loose. Fixt 5) Safety is loose. Fixt 6) Internal decorative carrier that covers hop is bent a little. Fixt 7) Needs a new pistolgrip- screw shear. Replaced Gun was functional as soon as I restored the fuse. I'll post pics and do a review after I loctite all these screws. Best deal ever on a non BB combat machine. ( they thought it was BB but could not test it ) Did I mention it is all metal? I'm still ginning - more soon.
