GS-13 Quic-Kee Black Powder Scope Mount - R12

This is made for use on a Knight Rifle that has a Flat Receiver. Frankly, I know nothing about either scopes or Knight Rifles, so I am not any help here in describing this. It looks like it is complete, as the package has never been opened. it has a front and a rear mount and several screws are included. Somebody that wants this needs to jump all over it like white on rice.
