Hello,
I had the same problem but was able to solve it by shimming the scope mounts with a thin piece of plastic. Put it under the rear to raise the sighting and under the front to lower. I still plan to buy my son a better scope.

Here's what you need to know about Mil Dots and rangefinding.

When you look through the scope you should see 5 mil dots on each axis, your scope may have broad lines taking place of the 5th mil dot if it is a "modified" mil dot scope. For measuring purposes, 1 mil is the distance from the center of one dot to the center of the one directly above or below it. 3/4 of a mil is the distance from the top of one dot to the bottom of the one above it, or the "space in between dots". 1/4 mil comprises a single dot, the space between the top of one dot and the bottom of that same dot.

A quick calculation is Size of Target (In Yards) x 1000 / Size of target in mils = Range in Yards

Miliradian or "Mil" is an angular unit of measure, so if you were shooting at 1000 yards and moved up 1 miliradian that would be one inch impact moved up.

Anyway lets say you have a 30" target and we need to find the range... using your scope you place the bottom of the target at the CENTER of a mil dot and count how many mils up, good estimation is key... I'll draw a little text diagram, an asterisk * will be the target top and bottom, and parentheses () will be a mill dot
( * )--------(  )-----*---(  )
Now lets assume the asterisk on the left is the bottom of your target and the one on the right is the top, I put Ten Hyphens in between each dot so if you count from the left you should get about 1.6 Mils. Its real easy to do it in your head, you already know two whole dots is one mil so you just have to estimate whats to the right (or top if you were looking down a scope).

So we know the target is 30" and we have a Mil Reading of 1.6
30/36= .833 so 30" is .833 Yards

So now we can use the equation .833 x 1000 / 1.6 = 520.6 Yards is the distance of the target

Now you can also use Mil dots to do hold over for when the target moves or for wind and elevation but that gets extremely complicated.

There are many books and websites to confirm what I've said here, but the best way is to go out to your range and talk to some long range shooters and show them your rifle/scope etc and get hands on help.

SOURCE: rifle scope fogging

You can try to clear this your self. You will need a good sized clear plastic bag, say kitchen trashed can size. You will need to get your hands on some nitrogen or you can also use carbon dioxide. You will need some good electrical contact grease or Vaseline will also work. Take the focus lens off your scope, let it dry out. Now ck for any o-rings and try to find new if you can, put the grease on the screw threads.Put all the scope parts in the bag and pump up the bag with your nitrogen and tie off the bag but leave room so you can screw the lens back on once it has set for a little bit in the gas. This should let gas stay inside the scope so no moisture can get back inside to fog it up. Try that, sounds crazy but it will work.

### 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

### I need a scope guide instruction sheet for the Tasco 28a

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.

### Scope

2) Use a bean bag or rifle mount and make sure that your rifle doesnt move much from its original position throughout this process.

3) Aim with the scope and shoot at a large backstop which will allow you to see where your shot lands, where ever that may be, it doesnt matter at this point. Again, make sure your rifle doesnt move much when firing.

4) With the rifle in the same position, look through the scope and adjust the crosshairs over to where your shot landed.

5) The scope now sighted in with the rifle. Minimal adjustment may still be required but at least your well within the ball park.

Happy Shooting
