Solid adjustable scope cover. Get it!
Perfect cap for a Zulus HD eye side lens (would work for other end as well but that comes with a cap already). Have a few of these caps and love every one.

Excellent lens cap. Fits right & looks great!
Great cap! Fits perfect and protects the glass! What more could a scope want?

It gets the job done
I wanted a custom fit cover for my scope but there’s no cover made exclusively for my scope. I tried to make sense out of the ordering process until I realized that all I needed was the cover and not the hassle. So I went with the simple solution and it worked!

Scope Flop Up Cover
Was skeptical, but it is working as advertised, thank you very much.

Monstrum Flip-up Scope Covers (A+)
As always I love Monstrum products, and this one is no exception. I ordered the one I needed for my particular scope. Took it out of the package and it fit perfect and doesn't slip or move at all. I use these flip up covers for all of my scopes including ones that are not Monstrum and I've never had any problems so far with one exception of one cracking in the rubber that holds on to the scope but I had those covers for a couple years so it was time for a new set.Shipping was quick as always and was packaged well.

Rubber deteriorated in 2 yrs...
The rubber started deteriorating after just two years, which was disappointing. I contacted the company, and they supposedly sent out replacements a couple of days ago. I appreciate their response. I’ll update once they arrive.

What I asked for
Works really well so far. Fits well. Keeps the eye piece protected. Everything I asked for. I will be shooting with us this weekend so if something comes to light positive or negative, I will amend this.
