Have a KonusPro 4x32 riflescope-- there is a small phillips screw under the barrel of the scope-- what is this for? It turns freely in both directions... How much torque can be applied to the scope mounting clamps? They have adjusting bolts with heads for slotted screw driver-- if a torque figure is unavailable, how much wrist force can be applied: firm, tight or until force limit?

you may have run out of clicks or the adjustment internals are damaged

One of the things about bore sighting is there is no shock to the scope. They are meant to have some shock that goes along with an adjustment. Try smaller adjustments and tap the tube of the scope with a screw driver handle after every adjustment. Not so hard you dent it but hard enough to get stuff moving. Hope this Helps FixYa up.

On my Bushnell scope I have an adjustable angle ring that will bring in the view, it is held in place with 1 screw. remove it and pull down towards the windage and elevation adjustment screws. There are 3 tiny phillips screws, remove them. Then unscrew the end of the Eye Peice end peice with the lens in it. inside on the outer edge of the main tube there is a locking ring that keeps the eye peice from unscrewing off, remove it and unscrew the entire eye peice. you are now ready remove the inner tube. Be careful here this is where you can damage the cross hairs and lose the leaf spring that maintains pressure against the windage and elevation screws. When you reassemble after cleaning and with the elevation screw at 12 o'clock and windage screw at 3 o;colck, the leaf spring will be in the 7 or 8 O"clock position, it just sits in there up against a little ridge inside, with the bow facing to the center. Back off the elevation and windage screws all the way so they don't block the inner tube from going in all the way. Once it is in adjust it so the cross hairs are orented correctly and put it back together. If you want to refill with Nitrogen remove the front lense and take to someone that fills tires with Nitrogen and inject the nitrogen into the scope, Quickly reinstall the front lens as nitrogen is about 3% lighter than air and if you take too long it will all escape.
This worked well for me. Good Luck and Happy shooting

the reticle should be level if its not you need to turn the scope body round in its mounts till it is level and then nip the scope caps up

all scopes are marked for up or down with a " u or d" or a
"+ or -" for up and down
just dont forse the turret screws or you will bust the scope

Yes, rim fire scopes can't be used on a stronger firearm as the recoil will alter the internal mechanism. I fought with scopes of all types for years until I bought a used Leopold, never finding a better one! Hope you can find one of those.

You don't if you want it to work right again as they are filled with nitrogen gas to keep them from fogging.

this will need to be sent to bushnell for repair and they can be reached at 800-423-3537 option 1.
