Nice caps - Trijicon ACOG 4x32 Flip Cap Set (Requires TA91 killFLASH)

Decent caps that do the job. Not very expensive. They flip up and close securely. Had a little trouble getting them installed. They were a little tight and took some effort to get them to stretch onto the scope. I don't think they'll be coming off very easily. Which is a good thing. Like I said, they do the job. They keep dust and other debris off the glass. They are a little less expensive than what I could find on the shelf locally. Getting the exact product for my ACOG and not having to drive anywhere or pay local sales tax, makes it an easy choice to get these from OpticsPlanet.
Pros: They do the job.
Cons: A little tough to get on the scope.
