Simmons 8x32-44ao rifle scope

Depends on the scope and rifle type to which it is attached.
I invested in an inexpensive laser bore such as this one for an AR: SightMark AccuDot Laser Bore Sight - 223 Model SM39001 (for AR-15)
Once the scope is mounted properly, and assuming you have not made any vertical or horizontal adjustments, set the rifle on a stable platform, insert the bore sight, point it at a target 50 (rimfire) to 100 (AR) yards out (works best in low light situation).
Once you have the laser centered on your target, make elevation and windage adjustments as necessary placing the scope cross hairs over the laser. Remove the bore sight and fire 3 rounds, then fine tune elevation and windage.

Your scope has 5 adjustments:
1. Eye piece focus - used to focus on the reticle.
2. windage adjustment - should be on the R side of the scope, adjusts lateral impact point.
3. Vertical adjustment - the top turret. Adjusts vertical point of impact.
4. Power ring - adjusts the magnification of the scope.
5. AO ring - Parralax adjustment - used to focus the scope at specific distances. Most markings are not exact, you should set it at the range you are shooting and fine tune focus when you look through the scope.

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.

Yes there is a screw on cap covering the adjustments. Here is one of there general manuals on the link below.

1. Insert the Bore Stud into the Stanchion while aligning the arrows as shows. Insert the assembled scope guide into the muzzle of your rifle with the grid pattern upright. 2. Select the Aperture Cap that fits your objective rim. Place it over the objective end of your rifle scope and press until it fits flatly against the rim. 3. Using the Adjustable Scale measure the top of your rifle scope tube to the center of the rifle bore as follows: Open the rifle breach. Rest the upper arm of the scale on the scope tube before or behind the windage and elevation turrets. The scale markings should be facing towards you reading vertically and ascending from bottom to top. Slide the lower end of the scale up or down until it is touching the center point of the bore. On center fire rifles the center point will be the firing pin. On rimfire models the center will be the shell extractor. Read the number that corresponds to the indicator marked "CF". Make a note of the reading. 4. Aim the rifle toward a light, flatly lit area such as a wall or open sky. Caution: Do Not Look At The Sun As Permanent Eye Injury Could Result. 5. While keeping the riflescope at the right distance to see the full field of view, sight through it on the grid pattern. Move the stanchion right or left until the bold centerline is parallel to the vertical reticule wire. Turn the windage dial right or left until the vertical reticule is aligned with the grid centerline. 6. Use the reading from the scale to align the horizontal reticule wire. Find the numbered horizontal grid line that corresponds to the number on the scale. Turn the elevation dial right or left until the horizontal reticule wire aligns with this corresponding grid line. 7. To make your final zeroing adjustments remove the scope guide from the bore of your rifle. WARNING: FIREING YOUR RIFLE WITHOUT REMOVING THE SCOPE GUIDE MAY CAUSE DAMAGE TO YOUR RIFLE AND OR CAUSE YOU INJURY At a range or other safe area test fire a group of three rounds of the same type ammunition at a target at least 50 yards away. Refine your scope alignment by adjusting the windage and elevation dials. Move to your desired distance from the target and test fire another group and make your final windage and elevation adjustments. 8. Restore the stud tension by pressing the end of the spring.

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,

From any reputable gun shop that stocks simmons scopes.

Sounds like you want to "re-sight" in your rifle. Make sure mounts are okay and tight. Look down barrel and then thru scope and eyeball windage and elevation adjustments so the scope seems to be fairly in line.

Clean barrel if it needs it.

For basic sight in, start at 25 yards with a large(3 to 4 feet) cardboard or wood backdrop around target (bullseye). Fire at target. Once done, look through scope and position rifle such that the shot mark you created is dead zero. Hold rifle very steady and you or buddy move windage and elevation adjustments until scope moves dead zero back toward original target (bullseye). Fine tune from there. Air cool rifle between rounds. Once dead eye, fire another round or two to check grouping. Check your ballistics (sometimes on ammo box) to see how height at 25 yards affects your desired dead on target (100 yards, 150 yards, 250 yards etc.). Adjust accordingly. Example: you may need to sight in at an inch high at 25 yards, depending on your dead on target distance..

Always remove sling from barrel when sighting in.

Try to sight in at similar temperature as you intended shooting temperatures, if possible.

If not black powder, avoid cleaning barrel between sight in and hunt/competition unless you note bad buildup inside.

If you change ammo, understand that that may affect performance. Once a preferred ammo is found, some even try to buy a decent quantity with the same lot number on the boxes if storage allows for such.

WARNING: FIREING YOUR RIFLE WITHOUT REMOVING THE SCOPE GUIDE MAY CAUSE DAMAGE TO YOUR RIFLE AND OR CAUSE YOU INJURY

At a range or other safe area test fire a group of three rounds of the same type ammunition at a target at least 50 yards away. Refine your scope alignment by adjusting the windage and elevation dials. Move to your desired distance from the target and test fire another group and make your final windage and elevation adjustments.

8. Restore the stud tension by pressing the end of the spring.

I'm not sure how this got posted in the car audio section...

 

If the scope was manufactured by a well established company, you should be able to get a new cap from them.

 

If you cannot locate the manufacturer, you can move the other cap to the windage adjustment to set the windage. Then when you're finished, move the cap back to the elevation adjustment.

 

Even if you use it for a shooting discipline that requires constant adjustment, it's unlikely that you'll need to use the windage adjustment for anything other than setting the zero.
