I just bought my first ar I use to be an ak man anyhow I tested my gun on a tin can from 5 maybe 7 feet away and missed 3 times lol now I know im not that bad of a shot ha but it seems to me that my front sight is sitting super higher than my back round sight that I look through so I put a bore laser in and tried to line it up and for me to see my bore laser I cant look through my circle back sights it seems as if my front sight is way way way to high up and when I look though my rear sights if I line them up correctly im l ike 5 or 6 inches low how can I fix this does anyone understand what I am trying to say ?

i don't have no way to post a photo but I will try to explain better if I look through my back rear circler sights and I line my front sight up into the circle im shooting 5 to 7 inches low .. and if I want to hitmy target I pretty much cant use my rear sights at all I just have to line up the tip of my front and its level but if I use my rear sights to aim properly my front sights is way to high up to be on target I noticed the front sight says up on it and an arrow if I keep turning it the opposite direction will my front sight eventually lower ? or does anyone know if smith n Wesson aims these m and p 15's sights when they ship them out factory or do they just throw them togeather
 
okay so maybe im just to close to what im shooting at ? and if I back away 25 30 yards the sights will be dead on ? that just doesn't make any sense to me it seems as if I did that I would still be shooting way to low but im no expert either
 
also im use to shooting with V sights like on 22 rifles and ak sights maybe im just not using these ar sights properly ivenever owned an ar until now and I haven't had no trigger time on an ar at all
 
thank you to who ever suggested moving back I did it with a bore sight from 30 yards and I think im pretty much dead on I believe I was using the circle sight improperly because ive never used these kinda sights before hopefully when I go to the range my bore laser is correct if it isn't I think ill just go with some sorta red dot or something where I can change the elevation
 
The trajectory of a .22LR rises for the first 40-50 yards. Then it starts to drop. If you zero at 25 yards you'll be pretty close out to 100, but shooting closer than 25 yards you will hit below POA. I zero my 22s at 25 yards and shoot them out to 100 accurately. Anything beyond 100 is difficult for me with a 22 due to the extreme bullet drop beyond 100. Some people can shoot out to 200 yards with one, though.
 
Keep in mind that the sights are about 2 inches above the barrel. Any aimed shot that is real close is going to be low, no matter how much you adjust the sights.
 
Perhaps this will help with regards to ballistics.

Generally, if you are 5-7 feet away from something, your bullet will impact LOW as it has yet to even reach the line of sight..

Sithlord, that is the best picture, explaining the line of sight and bullet travel that I have seen.
I just measured the distance from the center of barrel to front sight on my M&P 1522 and it is 2-1/2". So to the OP, if sights are set for 25 yards, anything closer will be low, up that 2-1/2"
I have a Ruger 1022 set up with a scope which is zeroed for 50 yards. I shot a racoon on my deck from only7 or 8 feet away. Almost missed the coon due to not compensating enough for that close range. Second shot was "point shooting" and it hit where I wanted.
 
Sounds like you figured it out. Like any other rifle, zero it for your preferred distance (25 or 50 yards typically). The front sight is adjustable. You can use an AR specific adjustment tool or small screwdriver to push down the detent and turn the sight. There are some general rules for holdover depending on your zero. Search some threads or spend some time out at the range to see where it hits at different distances.

Just for clarification, do you have an M&P 15-22 or one of the M&P 15 5.56mm rifles. You keep saying that this is your first AR, and while the M&P 15-22 is an AR styled rifle, it really isn't an AR...
 
Also, if I may make a suggestion:
Using proper grammar, spelling, and punctuation will make your posts easier to read and increases the likelihood of an accurate and helpful reply.

That being said, the other posters have covered the most likely issues you are having. The height-above-bore for sights and optics on AR-pattern rifles requires you to think about target distance, point of aim, and point of impact. If you understand how these factors affect your shooting, you will be able to decide where to zero your sights/optics for your most common shooting distance. You will also be able to determine the best hold over/hold under for other distances.
This all comes with practice and familiarity.
