I have my irons zeroed in but the rear sight needs to be lower because the bullet is hitting a few inches above the front sight but the rear sight cannot go any lower. Is there any way I can raise the front sight up so the bullet will hit exactly where it is? Instead of having to aim a few inches low everytime

Turn it counterclockwise.  One click or 1/4 turn is 1/4 inch at 25 yards.  Press the detent and spin with a ballpoint pen, bullet, or similar.

Yes, he is asking about the front sight.  If you go to the information/guides section of this website there is instructions for sighting in your rifle.  You set the rear iron sights down to 300 yards, set up a target at 25 yards, and you then adjust the front sight for elevation.  The front post has a spring loaded pin holding the front sight from spinning up and down.  Push that pin in and turn the front post.   When that is done and the rifle is shooting on target, you are zeroed and the rest of the elevation settings on the rear sight should be accurate automatically.

You can also buy a longer front sight post if needed.  Bushmaster and others have these.

I purchased key ring tools for the 4 an 5 detent AR sights from DPMS.  These tools are great.  Using a bullet to adjust the ft. sight is a pain.  DPMS sells the taller sight too, but I bet bushy is cheaper.

Quoted:
Try another zeroing method. The USMC 300 meter battlesight zero will bottom out your rear elevation wheel at 8/3 minus 3 clicks... or the improved battlesight zero will bottom out your rear elevation wheel at 8/3 minus 2 clicks. The latter method is most recommended. Both methods allow you to zero at 100 yards, 50 yards, etc. adjusting the front sight post using live ammo.
