Hi again. So, I was just going over my .22 to mount a scope on it, and did so sucessfully. Anyways, after I mounted it, I put the boresighter on it and it was out, which was expected. So I did a quick read, and found an article about setting the crosshairs on optical zero. I want and got a mirror as it says, and thery were out a fair bit. As I attempted to square it up, I noticed that the crosshairs did not move at all. Just bought it used so, I had no history on it, and it does look good and in good condition. Is there any possible way to fix this scope (Bushnell Banner 4x made in Korea) or is the consensus that it is toast? Anyways, thank you in advance for any help or advice given.
Scope Crosshairs Do Not Adjust

Yes immediately after I got it. I mounted it and shot it and was not very accurate, so I removed it to install at a later date. Today as I sa8d, the crosshairs were not even on the grid on my rifle. So well, there was no movement of the crosshairs as well as I attempted to adjust them while the boresighter was on. But, no I did not shoot it on the rifle, as it was way out in left field, and not offering any adjustment.

Think of your scope as a tube within a tube. The cross hairs are mounted in the inner tube. The turret screws work against a spring on the opposite side so that turning the turret screw inwards, will push the inner tube over, by pushing against that spring. When the turret screw is backed out, it is supposed to be that spring that pushes on the inner tube to cause the inner tube to follow the screw out. If you were backing the screws out, and the inner tube was not moving, than either the spring might be broken, or the mechanism is jammed up that the spring doesn't have enough strength to move it. Assuming there is no warranty and that you are at the point of chucking the scope, I would try turning the turret screws all the way out, then all the way in, then half the turns back out. This might get the innards to move?
I've shot with enough people and watched them make adjustments to their scope and then bang on it with their hand. I assume to make the scope move, since they used to stick in the old days and require a shot or recoil to shift them? I've seen it enough times that I caught myself doing it also...
With an older scope, I would run the turrets all the way in and back out to make sure that everything is moving
