Does the job intended - Butler Creek Multi-Flex Flip-Open Rifle Scope Eyepiece Lens Covers

Personally I like the old bungee style covers where you can just pull back on the ocular cover and both ends come off quickly. The only company seemingly to make these any more is Trijicon and they are pretty scope specific. I purchased two different sizes that would not fit so I decided to try these.

Obtaining the correct fit seems to be an issue. I happened to find an article that had the original Butler Creek Scope Cover Chart http://www.thefirearmblog.com/blog/2013/07/21/butler-creek-scope-cover-chart-convenience/. This table list scopes by manufacturer and model along with th4 correct size Butler Creek objective and ocular cap. This is what I used for my purchase.

I am not sure it is any faster to flip both covers off than to remove the bungee style but can see where these will be less likely to be lost since they stay on the scope. At least now both lenses are protected from dust and grime.
