Scope issue

[Spencie]

I have a Vortex Diamondback 3-9x40 on my Ruger 450. It is currently stuck on 5 power. The adjustment dial will not move either way. I contacted Vortex and they said I could send it back but to try adjusting the windage and elevation to see if that frees it up. If one is maxed out it could cause the variable adjustment ring to freeze up. Does this make any sense?
I don’t think either is maxed out and I’m not messing with it until I’m done with the gun for the season. The scope is most likely going to be returned regardless.

That sucks man! I know that Vortex no questions asked life time warrantee policy will replace it for you. I hope you make through the rest of the week with it, or better yet, put one down successfully.

Good luck!

The good thing in all of this is 5x will work in most cases. Sucks that it’s stuck but it’s good vortex stands behind their products

Bummer

Have you shot it on paper since it stuck to make sure whatever the problem is it isn’t affecting the zero?

 

[Spencie]

Yes. It’s dead on.

I'm not an optics engineer, but that seems like a really odd correlation to me.

My thought as well. Was the windage already maxed out before messing with it?

On most scopes there is a tube holding multiple lens that runs from the eyepiece to the turrets. Turning the screws in the turrets moves the end of the tube to change the point of aim. I guess I could see a situation where the tube binds the power adjustment ring.

Since I can never sleep until daylight I just looked into this problem. First I tried the elevation and windage adjustments to see if they were maxed out. They weren’t and that didn’t change anything. Next I loosened the scope rings. Bingo, I moved the scope 1/16” and the variable adjustment was freed up. I thought that might be the issue but wasn’t going to mess with it during season. Now to get some range time and it’s ready to go.

@Spencie
Mike since you’re going too sight it back in, you might want too pull the rings off and match the dimensions and see if there’s any significant difference be them. Even go as far as lapping them. Might preclude this from happening again.

Using alignment bars and lapping the rings is the best procedure when mounting a scope and torquing the screws - right on J

Yep
