I’ve been needing some covers for the scope on my hunting rifle. The rifle was a combo that came with a scope. Seems the scope is a Simmons Blazer, the 3-9x40mm model. A set of Butler Creek scope covers would be fine. Thing is, I didn’t know what size to get. So, I did the logical thing: I called Simmons to ask.

The guy on the phone said I wanted a 10 eye (1.516″/38.5mm) and a 28 objective (1.890″/40.0mm) (these are the regular flip-open models). So off to the store I went and bought them. Came home, put them on, and well… technically they fit, but really they don’t. They’re probably the exact size, but that made them just a hair big and thus they were loose. No way they would work. So, went back to the store looking for the next size down. No luck. I did find a 26 objective (1.820″/46.2mm) which was fairly tight but works, so I exchanged the 28 objective for the 26. I think a 27 objective (1.840″/46.7mm) would probably work… fit well so it wouldn’t fall off, but not be so tight that it’s difficult to remove (like the 26). I don’t know what eye I would need, but my initial guess is just one size smaller at a 9A eye (1.485″/33.7mm). It’s possible a 9 eye (1.468″/37.3mm) could be right, but no way I can know until I can try them. Apparently Cabela’s should have 9 and/or 9A, but I don’t feel like hauling all the way down there just for one of these. I’m sure I’ll be down there sooner or later anyway and I’ll look for one then.

Just wanted to put this information online for the search engines… in case someone else runs into this eventually.

BTW, here’s a handy Butler Creek scope cover size chart.
