Well, my first thought is that with standard 5.56 and a 16" barrel, you're only going to experience about 1"-1.5" drop at 100 yards, at 50 yards it's more like 0.2" drop. You may have been over-compensating for the anticipated bullet drop.
When zeroing a scope, you want to keep in mind that the scope is a fair distance above the center of the bore on an AR... anywhere from 1" to 3" or 4" depending on your rig. At 25 yards, zeroed, your scope is going to be aiming LOW at 50 yards, rather than high and it will be aiming VERY low at 100 yds on a 25 yd zero.
My advice would be to find out how to calculate scope offset based on how far above the bore your scope is mounted and use that information to adjust your scope to 50 or 100 yds after you re-zero it at 25 yds. You should be able to have your rifle dialed in at 100 yds using as few as 3 shots, but no more than 9 shots.

Here's what I do and it works well for me.

1 shot at 25... adjust accordingly to zero the scope to 25 yds (confirmation shots as needed to check scope adjustments), crunch your numbers to figure out how many clicks you need to go UP with your scope to adjust the zero from 25 to 50 yds, fire and check your 50 yd target... adjust accordingly to zero to 50 yds, crunch numbers, adjust scope up to zero at 100 yds, fire. Your rifle SHOULD be zeroed at 100 yds now.
Also, very close range + scope = bad.
Iron sights or red dots are good for close range. Scopes with more than 4x magnification are relatively useless for short range unless you plan to miss.

• This scope does not use batteries. It uses an IR or Illuminated Reciprocation. The light available is guided through a light track and illuminates the dot. The setting adjustment is used to allow less or more light through to illuminate.

A 20 MOA scope base may be if assistance. The built in 20 MOA of elevation will allow you additional adjustment.

I use a strap wrench for such tasks.

If you can move it, you should be able to unscrew it. If you can't us a strap wrench. It has worked for me in the past.

your crosshair actually needs to go lower to raise the point of impact. if thats what you meant than you have a mounting/scope problem. the scope should naturally align within the adjustment range assuming the mounts are correct and the scope is functioning and mounted properly.

I ASSUME this device has collimation screws on the side of the barrel-- if it does not then the prism cannot be aligned.

If it does have collimation screws then hold the small monocular up to a lighted window and adjust the screws until you get a ROUND circle of light-- if you see a "catseye" light circle the prism is not collimated.

You posted this in the Telescope forum.

You will not find a manual for this small telescope and replacement parts are not available.

Sorry

Telescopes that are advertised as having powers of 300, 500, 600 or whatever are scams. You will not be able to see anything but dim blurs if you attempt to use them at such magnifications.

There is a good website for telescope beginners that explains the issues clearly at THIS LINK
