I was curious about sunshade threads as I want to get a shade for a newly aquired 44mm Cabelas 6-18x

I was told that there is a shade listed for it but couldn't get a part number. It's apparently discontinued through Cabelas. And research is getting me nowhere

So I was wondering if they are they standardized? So I can get any old shade..

Eg. A 40mm shade will fit any threaded 40mm optic

The best advice is to go to Butler Creek website, measure your objective & eyepiece, and us those numbers to select the right size. Good Luck.
OK, that's the wrong advice, maybe if you were asking for flip up lens covers, LOL. Sunshade, Mmmm maybe try Sniper's Hide?
Since most of them thread in it may be hard to find something that works?

Nope, there are no standard. I bought a sunshade for a Bushnell scope which has the same objective size as my Tasco. They were not interchangeable.
 
Measure the internal/external diameter of your scope's objective bell's threads with a caliper. Do you happen to have a thread pitch gauge? I can check the spare sunshade I got.
 
Update:

The Cabela's "Pine Ridge" 44mm scope measurements

The bell is threaded on the EXTERIOR
Major thread diameter @ 48.90mm / 1.925"
Thread pitch @ Metric .6

The INSIDE measurement of the factory thread protector is @ 48.45mm

So that makes the threads @ .45mm deep...not that it really matters..
 
The sunshade I have is a Bushnell.

Diameter at the male threads is 49.95mm
Diameter at the female threads is 49.44mm

Couldn't find my thread pitch gauge in time 'cause I'm running late for work but sounds like my sunshade is already too big for your scope.
 
There's a slight chance that the Cabelas scopes are a modified production run from another manufacturer. For example, if Cabelas asked "ChiScopeCom" to make a signature brand scope, and they used existing model XYZ, but changed a few things, and labelled it Cabelas. If you could find the original manufacturer, that would help narrow down who made the housing, and then you might be able to find the original sunshade to fit.
 
I did a quick Google search, and found quite a few opinions from forums similar to this. Among those opinions (not copy/paste quotes, but the same meaning):

"Cabelas shops for the company who can produce the scope they spec-out, for the best price. Companies can vary"

"Some scopes look suspiciously like Sightrons, others like Tascos"

"Cabelas is very secretive about the original manufacturers. But they will disclose the country of manufacturer"

and "Chinese made scopes are not all junk - it depends on the factory, materials, and labour used in the factory, to determine the quality, or lack thereof, of product".

So none of that helps you at all. If everybody had a micrometer and thread pitch guage, a general broadcast out to a group the size of CGN, asking for Manufacturer, model (if available), diameters, and thread of sunshades, would produce a really nice table, from which you'd almost certainly find a match (you gotta know these Cabela scopes were not made in a factory built and tooled only to make this one model of scope, then torn down afterwards. There must be a compatible shade somewhere, under a different name).

Can you post a couple pics of the scope - so we can see the general shape, turrets, bell, how the labelling is done? I'd bet the tube shape, at least, would be the same as Scope-X, and go from there.
 
A quick search on "44mm Cabelas 6-18x" gave me more responses along the lines of "44mm 6-18x", but in that, there are Cabelas Pine Ridge (which I saw mentioned in some of the forums), Redfield Revenge also has a 44mm 6-18x... probably others. Comparing pics will get us part-way there.

Edit: Others: Sightmark, Truglo, Hawke Sport Optics, Nikon Monarch, etc.

You might be able to email them to get more precise measurements. It sounds promising.
