I got a scope and mount on a Poly I traded for and don't know what I have. I hear of different 'generations" of Springfield scope mounts, but don't know the difference. This one has two big slotted screws on the side. One goes into the reciever and the other goes into a piece that replaces the clip guide. It is marked on the side: SPRINGFIELD ARMORY Geneseo, Illinois and appears to be parked aluminum. Which mount is it? The scope is a rubber armored Tasco 3-9X40 and has Butler Creek flip up caps. I also don't have a clue what this set up is worth and may sell them as I'm partial to open sights. Anyone know what these parts sell for new and what they should be worth used? TIA. AIRBORNE!
