Length of scope & accuracy

[lexcruiser]

I was wondering if anyone had knowledge of this.. but does the length of a scope have any effect on its accuracy?

I'm currently shopping for some new optics for the 15-22 and there are a huge variety.

Some are "ultra-compact" and offer decent 4-9x zoom. While full size ones also offer the same zoom levels. Would the accuracy of both be different due to the length differences? Does the distance from front and rear lenses create a deviance in accuracy similar to the length of a barrel, but from a POV standpoint?

Does any of this make sense..?!? =P

Frankly, No.

You need to look at the internal specifications/capability of the scope in relation to your needs. For a .22, you don't need the eye relief and shock resistance of a hunting scope, but you do need the stability and repeatability. Nothing worse than a scope that shifts zero when you zoom.
Brightness and freedom from distortion save the headaches.
I like the Leupold .22 scopes, but they are pricey.
You usually only get what you pay for in scopes, but you can sure pay for it in some and NOT get it.

AS OKF said, no.

I just bought a small 8 inch 4X made by Tru-Glo. I wanted a small scope for a Marlin carbine, so as not to overwhelm the petite rifle. Looks fine.

The scope is great, repeatable adjustments, clear, but you DO sacrifice some optical parts of the triangle.

The eye relief is shorter, and the field of view is perhaps 35% smaller, than a comparable 12-13" 4X scope.

If you can live with that, go for it.

always understood it as FOV is a function of magnification and tube/lens diameter. ?

I think you are thinking of Exit Pupil which is lens diameter divided by magnification.

FOV is going to depend on the optics design and what angle they take in. For example, think of camera lenses - both a telephoto and a fisheye have the same lens diameter, but dramatically different fields of view
