Monstrum flip up scope lense cover

[Dennyr]

Has anyone had any experience with these? I have 3 scopes that objective measures 2.150 and can't find a flip up cover that works. Maybe these will. Any ideas? Thanks

I have used them and they work good. I had an odd ball and they made one that worked since they stretch slightly
