Many cap threads are reverse. try unscrewing the other direction. If this doesnt work my suggestion is to use physics to get it off.

Image a jar that is 1 litre with a lid that is 10 cm across. it takes x amount of force to unscrew that jar.
Now if that same jar has a lid that is 25 cm across there is a power advantage and a speed reduction.

Now to apply this to your thread caps. try adding layers of tape/cloth onto the thread caps to make it easier to unscrew.

SOURCE: Sighting in my scope

That should be covered in your manual.

If not, give Nikon a call.

Or, repost your question on a Bulletin Borad such as at SWFA, where another user may have the identical scope.

SOURCE: Cannot sight in riflescope for elevation, adjustment is maxed out

Try reversing the rings. Move the back one to the front, and the front one to the back. Turn your elevation adjustment, back to -0-, and start again.

SOURCE: sight adjustments

It's a common misconception that you are moving the bullet's impact on the target... the bullet is hitting where the rifle is pointing and you want to get the scope to look at that very same spot.
To move the scope's reticle up or down, turn the elevation adjustment on the TOP of the scope in the direction you want the scope to look, so if your shooting low, turn the scope's adjustment in the DOWN direction.
If you want to move the direction the scope is looking left or right, turn the windage adjustment on the RIGHT side of the scope left or right to look where the bullet is impacting. To move the crosshairs to the right, turn it right.
Hope this helps, Mark the Gunsmith

There should be a set screw or screw that you can loosen to make that adjustment. Once you have it where you like it, just tighten it back up and enjoy you ability to make those quick adjustments when needed.

My rifle is shooting about five inches high. Do I turn the elevation adjustment towards "up" or opposite of "up"?

If you have a scope, the adjustment is under the top cap, and you should turn the adjustment 'down'. If you have iron sights, you would adjust the rear sight in the same direction that you want to move the bullet on the target (also 'down'). The opposite is true if you are adjusting the front sight.

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.

Try some PB Blaster. Wet a q tip and apply to the area at the base of the turret caps. Wait a few minutes and reapply. Then using a small pair of vice grips attempt to twist the turret covers off.

Have no idea how to set up the sight on my air gun

I don't have this particular model. Chances are, those are not "knobs" but caps. Remove the caps as you would remove the caps from a pill bottle. Underneath, you should find the adjustment dials for windage and elevation,

I am trying to bore sight a rifle with a center point 4x16x40 and i run out of adjustment to get the lazer to align with the cross hairs

When bore sighting you need to adjust in small steps and "TAP" the bore or the main body of your scope to cause a golt, as when shooting your gun it will kick and cause the scope cross hairs to take their set.  Tap it with a med sized screw driver handle. Make a small adjustment and tap it, adjust and tap.

I have a model D-4 weaver rifle scope with missing adjustment par

Pretty much all rifle scopes have great warranties. Send it into weaver and i'm sure they will fix it plus replace any parts. I'm sure they will charge for missing parts but it would be best for them to look at it and check it out. TP
