Sighting in red dot shotgun scope

For magnified scopes and plain old red dot sights, there are usually two dials you adjust - one for up and down, one for left and right.
My ACOG replica and BSA red dot sights require a small flat head to be able to adjust said dials. Most sights follow the same thing, aside from holo sights which have buttons that don't require tools.

should be a shallow slot on the scope that looks like a quarter will fit to loosen cap. Just use a quarter and turn counter-clockwise.

No, that doesn't sound stupid. It's always a good idea to get all the information before using firearms and their accessories, and I'm happy to help:

The large knob on top of the scope is the rheostat, which is used to turn on the red dot, and adjust the brightness. It can be adjusted from "1" (dimmest) to "11" (brightest). You'll have to be looking straight down the scope to see the red dot, since it is only visible when you're aiming. If you turn on the scope to the brightest setting, and you look through like you are aiming, and the red dot is still not there (or very dim) then you probably need to replace the battery. It uses a 3 Volt coin-style lithium battery, type 2032. Unscrew the battery compartment on top of the rheostat and put the new battery "+" side up. Then replace the battery cover, and you should be good to go. Turn off the scope when you're done to save the batteries.

Since you bought the rifle with the scope already installed, it's probably already sighted in, or pretty close to being sighted in. Adjusting the windage and elevation on the red dot scope works just like other rifle scopes. The knob on top moves the point of impact up/down, and the knob on the side moves left/right. For this model, each click of adjustment moves the point fo impact by 1/2" at 100 yds, 1/4" at 50 yds, or 1/8" at 25 yds.

Be safe, and have fun!

Check out Amazon They list a scope mount for that gun.

I would try oiling the mechanism first, and it may have a trigger adjustment that may be modified for the trigger pull. Odds are it may have some friction on the trigger mechanism at first and may just need some lube. Try this and if all else fails, take it to the dealer that you purchased it from and have them evaluate it.
Hope this helps

there are knobs on the top and side of the scope, unscrew the black cover to them and you use a screwdriver to turn the knob to adjust it

Just a feeling here so don't cuss me (lol)....try turning the adjust knob "the other way". Just take your screwdriver or your quarter or whatever you're using and turn the adjust screw ALL THE WAY THE OTHER WAY and see where it hits. If it's moved, proceed to adjust it. Word of warning, though....a shotgun isn't going to move the crosshairs much at all in its intended range. Shooting it at 30 yards or so, you're going to have a hard time with ANY scope. A slug at 60-100 yards, you would see an adjustment but not shot at close ranges

I doubt if there is anything wrong with your scope.
The Baraska model A10810 Reticle adjustments are 1/8 ( 1/8 inch) MOA (minute of angle).
For instance, Look at the top turret (The ELEVATION Adjustment Knob). You will see that there are little vertical 'hashmarks' all the way around the knob starting with a '0' then a series of the verticle hashmarks, then a '1' and another series of the marks, then a '2' and so on. YOUR scope will have 8 of those vertical 'hashmarks' between each 'number'. These little 'hashmarks are referred to as 'Clicks' or 'Minute of Angle' adjustments.
Now imagine that you are set up on the 100 yard line and you have fired a round at your target, say a one inch diameter dot or any size for that matter, and the bullet strike was one (1) inch LOW and two (2) inches to the RIGHT and of course you now want your next round to impact in the target dot.
To bring your bullets point of impact UP to coincide with your point of aim (you have your 'crosshairs or RETICLES centered on the dot), you will be turning the TOP adjustment knob CLOCKWISE, ONE 'click' at a time. EACH one of those 'Clicks' will actually move the horizontal Reticle UP (Elevation) or DOWN 1/8 of an inch at a time. If the bullets point of impact was 1 inch LOW, you would need to turn the adjustment knob clockwise Eight (8) clicks which will equal ONE (1) inch.
Now you must adjust the knob on the RIGHT side of the scope. This one is the WINDAGE Adjustment knob which controls the VERTICAL Reticle and moves the point of impact Right or Left. This knob will also have the 'hashmark' increments around its perimeter and like the Elevation knob each 'Click' will move the Reticle 1/8 of an inch but in this case the Reticle and point of impact moves Right or Left.
Remember the bullets point of impact was 2 inches to the RIGHT. This means you must adjust the Reticle or point of impact to the LEFT so that your point of impact will coincide with your point of aim and will be in the target dot. Turn the adjustment knob COUNTER CLOCKWISE Sixteen (16) Clicks. Keeping your POINT of AIM (crosshairs centered on the dot), your next round should be inside the dot and you can then fine tune it from there.
As you can see from this example, the Reticle (crosshairs)and point of impact does not travel very far at all inside your scope at the 100 yard distance so it is not hard to imagine that you thought they were not adjusting to get you on target, when in fact they WERE adjusting, but in tiny increments.
Now, as you create more distance between you and your target, these 'tiny' increments and point of impact will be larger as your distance increases. For example, at 200 YARDS each 'click' will move your Point Of Impact 1/4 of an inch right,left,up, or down. So if your bullet point of impact was one (1) inch low from the 200 yd line you would adjust your Elevation Reticle 4 Clicks to raise your point of impact in order to be on target. At the 300 yd line each Click will adjust the point of impact up,down,right or left, ONE (1) inch.
If you wish, I would be happy to walk you through the 'ZEROing In' of your scope and rifle even if you do not have a Zero Bore Scope. With-in about 9 rounds you can be hitting where you are aiming instead of 'chasing' bullet holes all over the paper.
If you are interested, respond back and I will be glad to assist you. Enjoy. :)

remove the screw on battery cover counter clockwise.  Replace the small button battery and carefully replace the battery cover and don't forget the o ring.
