I have finally went big time and have a new NXS 5.5 x 22 x 56 Nightforce scope ordered from Bob Beck. Does anyone use the Butler Creek scope caps on their Nightforce and could you tell me what size (number) I will need? Also, if anyone has any other recommendations for protecting the lens or is using something different I would appreciate your comments. I know it will come with the rubber bikini lens protector - would this be satisfactory or should I just go ahead and get the Butler Creek scope covers? I've used these caps before and have them on several other guns and they seem to work fine. Your suggestions or advice would be most appreciated.
