Butler creek sizes

The manufacturers website for my scope says it has a 56 mm bell and 40mm eye piece, i measured it with a crappy ruler i have as its all i had and it does have a 56 mm bell but the eye piece seems slightly under 40mm so wondering what size butler creeks should i go for

I looked up the size chart and for the objective it says
53.3 mm size 34
56.4 mm size 39

Eye piece
39.4 mm size 11
39.9 mm size 13

Would i be better of going for the size 34 and 11? Or in you experience using them would a 53.3mm stretch to 56mm and a 56.6mm be too loose for 56.0mm

Same for eye piece, cheers guys

What scope is it ormond, maybe someone has the same and can tell you the exact butler creeks they have.

If it's a S&B 2.5 - 10 X 56 I have Butler Creek flip up fitted and can measure if required.

My zeiss conquest has a objective of 56mm and the 39 cap is a good tight fit on it.
What scope is it ?

Don't do this. I bought a size smaller (by mistake, and thought i'd make it stretch. It fitted, but the cover on the housing was stretched so far the clasp did not hold the flip cap, and it keep opening. that's when i could get it closed of course.

Try and get the right fit for it.

As for sizes.

For the Objective lens i'd go for the size 39 (56.4mm), and for the eye piece you need to look at;

• Size 9 - 37.3 mm
• Size 9A - 37.9 mm
• Size 10 - 38.5 mm
• Size 11 - 39.4 mm
• Size 13 - 39.9 mm

If the eyepiece is slightly smaller than the stated 40mm size one of the above will work.

I wasnt sure about my sizes so I bought the Multiflex Covers by Butler Creek. They are stretchy and give you a size above and below to play with.

Measuring never seems to work. I have tried and always get ones that are too tight or loose. I usually order two sets and return the one I do not need.

There was a chart that you could print out and physically place the scope over a bunch of centered curves to determine the size you needed.

Sorry I cannot provide a clean copy, here's the best I can do.

Sorry about the size!

You should borrow a set of calipers and measure the scope properly and then order the cap to suit.
It always works for me.

why don't you just bring the rifle into the shop and try a few on to see what fits?

ormondprop

They can be got a lot cheaper online and i have no way of obtaining a calipers either, i reckon i'll just measure it as close as possible and order the two closest sizes

Ormondprop,
measure the circumference and divide by 3.14 = diameter if you don't have a calipers.

At a gun show in WA last year we asked the guy on the Butler-Creek stand why they had adopted these wacky cod numbers, instead of doing what most makers would do - measure the size of the bell and use THAT as the 'code' number. So a #56 would fit a 56mm bell. Seems a plan to me.

He looked at us as though we were talking to him in Sanskrit - he totally failed to understand our reasoning.
