Red Dot adjustment reversed, why?

[ducatiti]

Can someone explain the logic why moving the dot to the left, will move the point of impact to the right?

And when moving the dot down, will make the point of impact go higher?

Reason I ask is because each adjustment dial moves opposite of what it says. it has the word up and turn counterclockwise, but dot actually goes down. For the windage, arrow turning counterclockwise and word right but the dot actually moves left lol.

I can't seem to find a good write up explain this.

Thank you.

OK, when the dot is moved left, you compensate by moving your point of aim right to put the dot on target. Same with up and down. You compensate by moving your point of aim opposite of the direction the dot moves.

Use a finger on each hand to emulate the dot and the target. Move the 'dot' and get back on target.

Because you are actually superimposing the dot over the bullet strike when you make a sight adjustment on a red dot (the same thing happens with the crosshair of a normal scope).

Assume you are striking 1" low and 3" to the right at 100 yards with a 1moa click adjustment. You would follow the sight adjustment instructions to move the bullet impact point 3 clicks left and one click up to hit the bullseye. What your sight adjustment actually does is move the dot 3 clicks right and one click down coinciding the dot with point of impact. Once the red dot and bullet impact are aligned you merely place the red dot on the bullseye for subsequent shots.

The dot placement and barrel axis. If your dot is on bullseye and barrel points left, the impact will be left of bullseye. As the dot is adjusted (moved) left, placing it back on bullseye will turn the barrel axis to the right. So to move your impact to the right you adjust the dot to the left.

The logic, is to make it easy for the user to comprehend where you want the bullet to impact. Most scopes or red dots come with instructions how to zero, that’s if you mount it correctly. Think of the dot as your front sight. If you drift it right your bullet impact will move left. Shorten the height and the impact will move up. The adjustment dials on your red dot is making it easy for you which way you want to move the bullet, if clockwise arrow wraps around the “L” turning it clockwise will move the BULLET IMPACT to the left.

I remember a rifle shooter at the range trying to zero his scope, but he mounted his scope making his windage adjustment knob as the vertical. He was very confused which way to turn the dials for he was still expecting the bullet impact to move up when dialing according to the instructions. I guess he skipped the scope mounting instructions.

That fellow was not as bad as the one I watched turn his scope’s adjustment protection caps. He said he maxed out his scope’s adjustment as the cap won’t turn clockwise anymore.

Thank you all for your inputs. I will continue to read them over and over till it sticks to my head lol.

For now, I have purchased a laser boresight in an effort to make it easier to zero both my RDS and Lasers.

Just think of it as a front sight. Whenever you adjust a front sight, you always move it opposite to desired impact shift. That causes you to swing the muzzle more to where you want the impact when you aim.

Thank you sir.

In regards to iron sights, I have to move the rear sight to the right to move the POI to the right correct?

Old sighting acronym for fixed Iron sights; FORS: Front Opposite Rear Same

To change point of impact, move the front sight in the opposite direction to move the muzzle towards the desired direction
move the rear sight in the same direction to move the muzzle in the desired direction.

Thanks. This will help a lot.

When the dot moves down, the barrel is moving up putting the shot higher.

Ive always wondered this too..

I get the fact that you need to move it opposite from where the bullet is landing on paper. But the dot still should move the way that the optic says it will. Lots of optics have an arrow that says R or L or up/down. And its always opposite then what it tells you its going to do.

Kinda annoying.

Because the focus is on where you want to move the impact, not the dot.
