Who makes good flip-up scope covers.  I am tired of those goofy caps that come with scopes and the last time I bought a set of flip-up covers they were crap.  

Butler Creek makes pretty good flip-ups.  They even market ones called "Blizzards" that have a see through lens you can leave down or flip up at your pleasure.

Cloak and Troy are right. Butler Creeks are the ONLY decent flip covers. You should be able to get them at your local sporting goods store (if they are a decent store and sell guns and scopes.)

If not you can get them from Cabelas or Red Head online. You should check carefully before ordering because they are different sizes.

Sorry I don't have links to post but just run a search on Cabelas or Red Head and you should find their sites.

I have flip ups on both my bolt rifles and they work great.

Good luck.
