Mine is now sitting in the box, but I am reluctant to part with it. Should I decide to sell the rifle some day, there is more value added to having the sights in the bag with the manual, in the original box. Sorry, I can not help.
If I buy a second one, I think I would go this route; might be a solution for you too: http s://www.amazon.ca/Air-Venturi-70809-Williams-Diopter/dp/B0085V1R44/ref=pd_sim_200_5?_encoding=UTF8&psc=1&refRID=T7X59 XMXVVZPMQRDJB98
