Flip Cover for scopes

[Derp]

Hi, I have 2 copes and I need some flip covers for them, but I'm not sure the size. They are both 3-9x40. 1st is Simmons Prohunter 8-Point http://cgi.ebay.com/Simmons-8-Point-Riflescope-3-9x40-Rifle-Scope-860654_W0QQitemZ220071992471QQcmdZViewItem#ebaypho tohosting


and the second is a Simmons Prohunter http://www.riflescopes.com/departments/247/rifle_scopes/simmons_rifle_scopes/simmons_prohunter_rifle_scopes.htm

Here is a chart

Last of all, how much are these flipper covers?

Thanks for you help!:)

Do yourself a favour, take the scope to a store that carries them and test them till you get the fit you want. The dia on the cards usually is a measurment of the outside of each bell.

Sounds great!
