Default how do you adjust a red dot scope?

Mine shoots real high.

Make sure it is mounted solidly, and turn the adjustment screw according to where it needs to be adjusted. Sorry to be vague, but it would help if you listed the type of sight in question

1st, mount the weapon so it doesnt move

2nd, take a shot

3rd, move the dot to the point of impact

4th, take another shot for accuracy, and make any final adjustments

Make sure your focus is on the target, and not the dot.

Here is my procedure for my Aimpoint PRO.

1. Shoot from a solid rest be it your arms on a rest, on a bag or a sled.

2. Shoot a 3-5 round group aiming at bullseye (hopefully you are able to group within a few inches) and dont worry about where they fall as long as they are decently grouped together.

3. HERE IS THE ZEROING PART. Aim again at the bullseye or whatever you were aiming at and missing and hold the rifle totally still. I'll have a friend or my Padre turn the elevation and windage knobs to line the dot up on where the point of impact was while I hold the rifle perfectly still like I was still pointing at bullseye.

4. Once the dot is now pointing at the group of shots, you should be zeroed.

5. Do another 3-5 shot group and you should be on bullseye. If you arent, repeat step 3 and 5 until you are satisfied.

I can do this in 6 shots total and be sure that I am on target. After that, you are the one to blame.

BTW, this is how to zero all scopes and optics using live rounds. You can use laser boresighters to get on paper but getting dialed in requires real bullets.

I always shoot 3 rounds and adjust the group. Remember that you are moving bullet impacts on paper. If you are high and right, you have to adjust the sight down and left.

Im gonna disagree with you there. If you are shooting at a bullseye and reticle is directly on that bullseye but when you shoot it is 1 mil high and 1 mil right, you need to raise the reticle 1 mil up and 1 mil right (although the adjustments are usually marked backwards so if you want to adjust left it actually moves the reticle right).

If you made your adjustment to click a mil down and a mil left and resighted on the bullesye, you'd now be shooting 2 mils high and 2 mils right.

At times when I cannot hit paper the first few rounds out, I aim at a spot on the berm which is generally far larger than a target, then adjust it in from there; once close I shoot the paper and zero it in.

I tried one of those laser rounds, wow, was not even close. More effort getting the laser zero'd than my weapon.

I tried to use a red laser bore-sighter to zero a Vortex Sparc mini red dot sight but I couldn't see the laser with it. I was thinking that the lens coating on the sight may have filtered out the laser? I have no problem seeing the same red laser dot when I've used the bore sighter to zero a scope.

For red dots, I use a 50yrd zero. This guy has a pretty good vid that explains it:

Use the look through the bore method with the bolt pulled out first.

Like some have said, I shoot a couple rounds to see where it impacts. If bullet hits paper I adjust the dot to the impact holes. If it does not hit paper I shoot at the berm and adjust as close to the impact as possible. Once I get close I go back to the paper and do my fine adjustments, which still consists of shooting one round and adjusting red dot to impact hole.

Also I start at 25 yards and work my way out to whatever yard I want my red dot to zero.

I also set up two targets one above the other so when I'm satisfied with my zero I shoot at the non zeroing target for consistency.

Technically Opticsplanet is correct; if you're shooting high and right you move the elevation and windage adjustment turrets down and left respectively; the arrows on the turret indicate which way the bullet impact on target will move with adjustment. If I'm shooting 2" high and 1" right at 100 meters with a 1/4 m.o.a. click adjustment I move 8 clicks down and 4 clicks left.

If you have a very steady rifle rest you can reverse the procedure and move the crosshairs (without allowing the rifle to move) to match the bullet impact by starting with the crosshair centered on the bullseye and adjusting the knobs so the crosshair now covers the bullet impact spot (the one shot zero method) which is what I think you're saying with your "although the adjustments are usually marked backwards" comment. After which you'd need to readjust your rifle in it's steady rest to properly align the crosshair with the bullseye.

If you don't have a manual and you don't know which direction to turn the knobs, here's what I do. Pick a place where you can see the point of impact like a dirt berm and shoot at an object you can see easily like a large rock. The elevation adjustment is the one on top. Turn it about 10 clicks clockwise. See if the point of impact is lower or higher. If it got better keep turning clockwise until it's on target. If it gets worst, turn it counter clockwise 20 clicks and see if it gets better. Now you know which direction is up and which is down and you can fine tune it. Do the same with the windage knob on the side. Once you get close, you can fine tune it on paper.

Also, if you don't have an owner's manual, you can usually go to the manufacturer's web site and get an electronic version or at least instructions on how to make adjustments.
