Hi there, cant help with the value I am afraid, but does it have a spring or a gas ram system, and would it be possible to fit open sights? (I know these questions sound daft, but I am looking for an accurate, .177, springer with open sights!).....don't mind doing some modding at the muzzle end.

P.S.....Mods, this is not a offer to purchase, merely to assess suitability for my needs, .....If it does come up at a later date in a sales thread, I will take my chances of being logged in at that time!
