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.

What size do i need for my diamondback tactical 

Asked by: Cardenas26
Sizes E-10 and O-40 will fit your scope.
Answered by: Mike at Vortex Optics

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.

Hi There, Your website lists the 0-40 as fitting the Razor HD LH 3x15 42, but a couple responses list that the 0-44 should be used. Can you confirm which is best? Objective-40 Fits: RAZOR® HD LH™ RZR-1589 RZR-1572 RZR-1565 RZR-1558 Thanks!

Asked by: LSU327
The O-44 fits the 3-15x42 Razor HD LH better than the O-40 fits, as the O-40 will be very tight.
