I got this at the gunshow for $30. it was spray painted black, I sprayed some Simply Green on it, the paint started to flake off. Moly Koted, this will make a nice .22LR upper.

Derek45, I'm pretty certain, but I could be wrong, the "C" inside the square signifies it as a Colt product. If the front pivot is the same size as the rear, then it is an original M16. Not M16a1, as that had a forward assist behind the ejection port. If the front pivot is a larger hole, then you have a Colt SP1 upper receiver. This is the original commercial AR15 unit. Good find. I'd have paid $30 for it in a minute.

The front hole is the Military size, not the SP-1 size. It fits up well with my Bushmaster lowers. I guess it's an early M16 or USAF upper. Who knows where this thing has been. I'm glad I found it.
