Butler creek #51 sku:30510 was perfect fit for front objective on my Athlon Cronus 4.5-29x56 scope. There was no need to heat cap to stretch over lens as some people had mentioned..fits snug enough that not going to come off. #20 cap for eye piece.

It’s cheap junk. The cap will not stay closed and it’s not worth the time or effort to send it back. You got me this time butlercreek, but never again.

Scope cap works great, finding one that fit my Razor HD gen II 4.5-27X56 was a pain. The size 51 fits great.

This size 51 fits nicely on my thor 4. It opens a bit too easy, but no worries.

I felt it important to write in this review an answer to commentor "Ty" below, and his disappointments with these great scope covers. I am sorry you had trouble, but your two problems are due to "user error" rather than poor product performance. I know because I initially made both your mistakes myself. First, just like you, I thought the first time I used these terrific covers that they wouldn't stay closed also. It turned out that I had simply pushed them on too far, and the scope itself was extending too far into the cover itself, thus blocking the closing system. Just back out the cover about 3/16" and you will be good to go. Secondly, as to size, you must have simply measured your scope diameters rather..."casually". If there is ever a decision to be made as to proper size, buy the next SMALLER" size. There is enough give in the plastic to expand just right. Also, a smart commentor below who experienced a "too tight fit" just heated up the cover with a hair dryer, put them on the scope when still a little heat expanded, and they cooled down fitting beautifully. As to no red switch on your eyepiece, you must have ordered one of the Butler Creek covers that do not use the switch mechanism. They sell those also. This is a really good product when installed and/or measured correctly. Maybe this site didn't post your negative comment as a review instead of only as a "comment" because they knew your disappointments were derived from user error.

Love them as always. This isn't my first purchase or even my tenth so it's really a no brainer by me saying this is the possible tenth purchase cause I own them for every scoped rifle I own if that tells you something. Only weapons I don't have them on are the red dot w/BDC sight units I have on my autoloaders. I've even got them on my 338 Lapua with the Nightforce scope.

Works great on my Vortex Razor HD Gen II 4.5x27-56 scope. There was some concern it might be a touch loose, and Butler Creek recommended if it was to simply put a strip of electrical tape around the inside to get a tight fit. Didn't need It, it fits great.
