Rated 5 out of 5 by from Great cap Same high quality as the eyepiece cap. Fits snug on my Crossfire 3x9-40. Doesn't rotate on the bell when flipping open. Opens/closes nicely after a couple cycles. Get eyepiece and objective.

Which cover will fit my Nikon Buckmaster II 4-12-40mm BDC scope?

Asked by: dbrook
I tried to find the specs on that optic but couldn't locate them. I believe the O-40 will fit that optic but I recommend contacting Nikon for the outside diameter to make sure.

I have a Razor HD LH RZR-1589. Will the O-44 fit the sunshade that came with the scope or is it a one or the other situation between the sunshade or flip cover? Thanks!

Asked by: SilverFade
Yes, that Defender Flip Cap will fit over the sunshade on your Razor.

What size do i need for my diamondback tactical 

Asked by: Cardenas26
Sizes E-10 and O-40 will fit your scope.

so if these are sold as single flip caps, does one size fit front and back or how does this work?

Asked by: 125hilliard
We have multiple sizes designed to fit most scopes, if you have the outside diameters of your eyepiece and objective you can reference those to the sizes on our website to find the correct flip caps for your scope.

Just to clarify, is this a set of two flip cap? Or a single flip cap?

Asked by: wyatthorn
Our flip caps come as singles so you can choose the proper sizes for your scope.
