Are you using these on your Hawke Sidewinder30 Scope? If so, what size did you order? I'm having trouble finding the right size.
AZSteveI have a Hawke Sidewinder 30 6-24 x 56. The front cap is a size 48 (2.5 in, 63.5 mm) flip up and the rear cap is a size 19 (1.73 in, 43.9mm) flip open. You can find them on Amazon at http://www.amazon.com/gp/product/B000H2XED6?psc=1&redirect=true&ref_=oh_aui_detailpage_o07_s00. I hope this helps.
Thanks EddieFastEddieHi Antj. These are what you need for Hawke sidewinder tactical scope with 42mm objective.

You are absolutely correct. The only thing is I don't mind. I'm addicted to making purchases and I can always take them off.AlanDuring my firearms career, spanning some 60+ years, I have always found flip up covers to be a nuisance, even in severe weather. Just about the time you really need the scope, the covers were closed! I even tried those that B&L used to sell, that opened the front cover automatically when the rear one was opened. I didn't like those either. But then, that's just me.
