Bought my first flat top AR.
Got AIM flip-up sights on it.
Shooting way high!
Closest I can shot it is 50 yards!
I like to start out at 10 yards or so when I sight in a rifle!
So I have cranked the front sight up, way farther up, then I think I should have to!
I have been offered a bore sight! Just have not got it yet!
Just looking for ideas, why it would be shooting so high!
Other then bad or poor sights!
(And of course it could be the nut behind the trigger!!!)

Get a decent sight, not AIM chinese bullshit

Is your front sight on the barrel or on a forend?  How long is your barrel?

If forend: Check to make sure barrel is seated properly.  And check that the barrel extension is square to bore of upper.

If sights on a Picatinny, make sure they are seated properly. 

If either or both are off center you might not have enough adjustment on both sights to get to zero.  And the longer the barrel problem is compounded.

That was what I was thinking! To me just eyeing it!
It looks like the front sight, which is on a small
picatinny rail at the end of the forearm! Attached to the barrel!
It sure looks lower then the rear sight! By a 1/4 of an inch!
Going to level the rifle in a vice!
Then put a 3 foot level on top of the sights!
That should tell me a lot!
If the front is lower! Going back to store who sold them to me!
They all so sold me the AR as well!!!
They should of know they would not work!
Anyone else have any other ideas let me know!

What kind of rifle is it and do you have. A picture?

You must have a drop in forend now.   Get a free float forend.  The Picatinny rails on these are usually level with the upper Picatinny.

Changing to FF should make your groupings a little more accurate.  The less stuff touching the barrel, barrel harmonics are more consistent/repeatable.

I had MBUS on my AR once, windage was almost maxed out.  Turns out I needed to lap my upper to square it to the bore.

Sorry no picture yet!
But the front sight is lower!
The rail the rear sight sets on.
Only GOD knows, how much higher it is then the front rail!
You know how it goes! Happy you got new firearm!
Thought they would sell me what would work on said firearm!
Deer in the headlights!
Taking sight back, to show them. See if they will do me right!
I should not have to buy a second front sight!!!
If I do! It won't be from them!

What  kind of rifle is it?

Im betting on it being an oracle. They have those railed gas blocks that are too low for the flat top.

You need a railed gas block height front sight.  You bought the wrong one.

The only way that the store could have told you that you had the wrong parts is if you asked them.

The advantage in building/owning an AR type weapon is that you get to pick the parts that you install on it.

The bad part is that you are responsible for what you install on it, and you are going to make some mistakes before you learn what works, and what doesn't.

The store where you got the parts didn't know exactly what you were going to do with the parts, as far as they knew, you were working on more than one weapon.

Unless you asked them if the sights would worked on the gun the way you were assembling it, the mistake is on you.  Take the front sight off, the gun, and take it with you when you go to buy a replacement so you make sure that the next one is taller.  Start a spare parts box with the original front slight, and let it be a reminder.

Front sights that are mounted on a rail can be knocked out of adjustment easier than barrel mounted FSBs or front sights.  It's up to the assembler to make sure that the front sight mount is mounted square and secure.  Many Homebuilders have problems with loose front gas blocks and front sights.

Rail mounted front sights can more eaily be knocked out of adjustment, and can be out of adjustment from the beginning because the rails were not mounted squarely, and securely.  Many people don;t even notice that the front sights don't work consistently, because they are using a Red Dot or Scope mounted on the upper receiver rail, and not BUIS mounted on the handguard/rail..

Well first off the rifle is an Arm-a-lite.(Please no comment on how good or bad my choice is in firearms.)
Yes it has a rail on the gas block.
When I bought the rifle, I told the clerk, I well need sights!
He grab these, AIM sights. Thought he should know what goes on said rifle.
Wrong!!!
Took back the sights. They knew they had screwed up! After eight months they
wanted to know if I had the original packaging!
I told them they where lucky, I had the cardboard insert with the name and model number on it!
They only had one gas block front sight. They where cheaper
(No comment please, I know what I got.)
But they should get me on paper!
Yes got the difference back!
Once I'm sure the gun is going to run good! Which I have not had a problem with.
I may go to a red dot sight! And change out that gas block to a low profile one.
Put on a different forearm on as well!
Hope to get to the range in the next couple of days!
Let you know if I did find the target!

Armalite is a good choice... I figured the way you made it sound you didn't want us to know what kind of rifle you bought figuring it was a piece of s*** from the beginning.

But it's not it's a fine rifle. in fact it's better than fine.

The only problem you're having is with the sights that you purchased from the vendor that they didn't know what they were selling. 

You won't even need to put flip up sights on the gun if you're going to put a red dot on.  those flip up sights are generally for backups... last I checked you weren't fighting in the military so I don't think you'll ever need backup sights.... also people use backups that shoot competitive rifle matches.... if you don't do either then don't waste your money.

Well I got on paper!  At 50yards!
It was use closer that first shoot.
Then it had been for sure.
Well play with it a while. Moving out to 100 yard next time!
See how it works out!!!
Thanks for all the help!!!
