AR-15 A1 upper receiver complete plus buffer assem & stock

This is an AR-15A1 upper receiver. It is complete with the sight assembly dust cover and teardrop forward assist. I believe it is an Eagle Arms product, pre Armalite of Geneseo IL. It has had about three hundred rounds through it before being switched out. It is in great shape. Included is a pair of CAR handguards, M4 handguards and retaining collar. Also included is an A1 buttstock (surplus) and buffer assembly (tube,spring and buffer of RRA orgin)
