I have two upper receivers I would like to sell as a pair. One is an SP1 slabside colt upper. Large pin (with adaptor for small pin). Stripped with no sight assy, or dust cover. This one has an extra hole in the carry handle by previous owner.
The other is an A1 upper with forward assist and no brass deflector. This one has some damage from previous owner, but did not cause any functional problems on the rifle I had this on. Please see photo below.
