I would definitely want to go and look at it very closely ! It looks like it may be restorable, back to it's Original SP1 condition.
Just make sure that Flash-Hider isn't welded to the barrel, that would be something that would really drop the price for me, but it could be fixable.
The Stock, Handguards & Charging Handle are all easy to fix. Just get there and really check it out, and get it for a LOW, LOW Price, due to it's Rough and Mis-Matched condition.
GOOD LUCK !
