Butler creek flip open scope covers - Butler Creek Eyepiece Flip-Open Scope Covers

I own a bunch of these and they have always served me well.It used to be harder to get exactly the right fit but Optics Planet has made it real easy with their comprehensive lists and guidance on how many thousands over/under the nominal size they will fit. Just follow their recommendation to precisely measure your scope eyepiece and objective end diameters using vernier calipers prefferentially and you can't hardly miss. The last three sets I received from them fit perfectly.
