close quarters shooting and zeroing

I have not posted for a while, forgive me. This may be confusing. I am looking for a red dot or something for a pistol/carbine that I can zero at 5 yards. I am planning to get an AO scope that goes down to 3 yards but even that scope is much larger than a red dot until i get my folding brace/stock.

I have tried a couple red dots and I notice something very strange after bore sighting the red dot to 10 yards or further when I shot said red dot at 5 yards or less the shot is is a bout 3/4 -1/2 inch down. I almost have to aim a bit higher to hit where I want it to go at 5 yards.

The area in my basement is not very long. Also very far from places to shoot.

Is there a red dot that can adjust lower and no I don't want to use a red laser nor do I want to tilt the red dot.

Any advice would be appreciated.
 
All red dot sights that I've seen can easily be adjusted for height . Don't think that I've ever seen one that cannot be adjusted.

As others have said, since you are shooting at a close range, your adjustment will require more turns to effect a change in the dot placement.
I do the same. At my distance a "single" full turn on most sights (red dot and scope), changes the point of impact, by about 1-1/4".

So if you shoot at close range, adjust your sight in at that distance. You WILL need to change the dot/cross hairs when you shoot at longer distances. Just physics.

Hello with a red dot it comes down to height over bore line(closer to bore line the less deviation ). If you want to shoot at 5 yd you will have to zero at 5yds and probably use hold under at 10 yds. If you zero at 10 yds you will probably have to use hold over at 5 yds. Just try picturing your optic points down your barrel points up and your projectile is being pulled down by gravity as soon as it lives the barrel so you have 3 line. Your optic line going down, your barrel line going up and you projectile making an arch. I am not computer savvy so i can not post the link but if you google "bullet flight path ammoland" in google images you can see a diagram of what I'm trying to explain. Hope this helps Eric
