Question about BSA 312X40 Contender Series Rifle Scope with Side Parallax Adjustment

1 Answer

How to adjust elevation and horizontal to sight in?

I thought the knobs (top and right side) would adjust for sight in, it had no effect. Must be another adjustment knob, but, have lost the owners manual. An owners manual would be my best option if someone has one for the BSA Contender

Many thanks, Rich

According to their website, the adjustment knobs have a "Push-Pull" feature. It appears that you need to pull the knobs away from the tube to engage the adjustment mechanism. Once you have accomplished this, you should be able to adjust you Point Of Aim (POI), then push them back in to prevent inadvertent setting changes.

The reverse may also be true - pressing in to change the setting, pulling back out to lock in the adjustment.

Hope this helps

Which direction do you turn windage and elevation


To raise the point of impact, turn the elevation screw counterclockwise. To shift left, turn windage screw clockwise. If you raise the horizontal cross hair you will lower the point of impact of the bullet. If you move the vertical cross hair to the right the shot placement will go to the left. Make small adjustments tap the scope with a screwdriver handle to give it a shock, not to hard to help move the cross hairs and try to bore sight first. Hope this helps Fix ya up.

How do i use a 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.

I'm sure this will sound stupid, I just bought a rifle with a Tasco red dot scope on it and have no idea how to activate the scope. Any help would greatly be appreciated. Thanks


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!

Which knob you adjust for drop? What is the left knob for?


If you have 2 knobs, there should be no left knob. If you have a knob on the left, you have it mounted 90 degrees out of alignment. Loosen the rings and turn it 90 degrees clockwise. Once you do that, the knob on the top is the one you will use for elevation.

If you have 3 knobs, the left one is for parallax adjustment, focuses the scope for specific ranges. the top knob is the elevation adjustment in this case also.

What are the adjustment knobs on the windage position for? Is it to adjust sighting or to focus the scope? Why are they not covered like most scopes are


The adj knobs on there are for windage on the right and elevation on the top, if they are not covered, they are turret knobs for target shooting, not for hunting. The focus knob is the rear lens, it spins in and out to fit your eyesight. It usually focus on the crosshairs and the distance for most shooters, some will not be able to get it right because of their eyes. 98% will. Hope this helps.

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,

Windage and elevation not working barska 8-32*50mm


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. :)

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.

Which knob for elevation/vertical adjustment?


usually side. best thing to do is go to an indoor range and sight it in. Just know the ballistic for the round/weapon you are shooting. ie. An M-16 has the same trajectory at 36 yds as 300, that way you can sight in at 36yds.
