I have the following upper receivers (no barrel or B/BC/CH) for sale:
1. ***Sold*** Gray Colt marked SP1 smoothsided upper with A1 rear sight and ejection port cover. Standard small takedown pin holes. Upper has seen very little use, but does have some handling/storage marks. Also, someone used gray touchup paint to cover some scuffs on the top of the upper, under the carry handle area. $80 shipped in US.
2. Bushmaster A2 upper with rear sight assembly, forward assist, and ejection port cover. "FK" forging marked. Standard small takedown pin holes. Upper has been fired approx. 3K rds. Minor handling/use wear, but nothing serious. Was $95, now $85 shipped US.
I have pics of the uppers, but not sure how to post them here. I will gladly email them to any interested parties. Payment will need to be USPS money order and insurance will be extra if you desire it.
