Everything was in pretty rough shape and there were quite a few spots where surface rust was popping up. I found a spray called "Gunzilla" and when teamed with a soft, nylon wheel at about 1/2 speed from my dremel, the metal all came back to life! Don't get me wrong, it's not in "showroom new" condition, but it sure as hell doesn't look like its almost 40 years old or that it's been sitting, unprotected, in a basement for at least a decade...
I decided/was forced to go a different route w/ the stock... I noticed that I needed a new gas tube and couldn't find an original for under $70, used. I ended up finding a pretty good deal locally on a brand new, tapco intrafuse stock w/ the matching hand guard/gas tube, so I went that route. Planned on having it back together last night and at the range today, but per my luck, ran into an issue... talked to a local gunsmith this afternoon and will try to get it to him tomorrow. My fingers are crossed rather tightly!
