I do not like caps on a scope, normally. But that was for hunting. I just purchased my first AR style firearm, and a very nice Vortex scope to use in long range shooting. This is the first scope I have bought that cost 400+ dollars, so I want to protect the lens from damage. These pop-up caps fit like I bought them on the scope instead as an afterthought. They work wonderfully and I do believe they would be good an my hunting rifle, a complete change in my mind anyway.

Great flip cap.
Easy to install, I really like the way they fit. Unlike other flip caps, these have the Vortex warranty so if I ever have any issues, I know that they will take care of me.
