Hello, I just picked up a bushmaster AR-15 from the local gun show. Just noticed it only has 1 adjustment on the rear sight. The knob on the right side. Doesn't hace the one under. What are the differences between a1 a2 a3 etc... It is stamped xm15-e2s. What would be the best things to do first? Thanks.

max range?, i guess that depends on how good you can shoot, but around 500 yards accurately for most
Before you do anything to "trick it out", you need to decide how you will use it. You got an exceptionally accurate rifle, easily good for 500 m & beyond. If you are going to be using it for long range shooting, then your choice of a scope & ammo will become important.
Check out the ar15.com forum; the guys on that have a lot of good stuff to share with you.

just elevate the front pin to change elevation
a1s have the advantage of not having the yardage adjustment turn without you knowing it
If it has a knob for windage only, it sounds like an aftermarket A-1 style sight. The original A-1 style sights I carried when I was in was a flat wheel on the side not a knob. The wheel had holes in it and to change windage you had to depress a detent to spin it each hole. The detent was just strong enough to ruin a ball point pen. So you had to carry some kind of punch if you wanted to adjust the windage easily(read change it to your zero, if you borrowed a rifle). With the A-1 you had to move the front sight only up or down.
The big difference between A-1 and A-2 is that the A-2 is readily adjustable for long range. Complete with increments for specific known distances. I think it was a great improvement over the A-1. I personally wouldn't go back to the A-1 type sights unless I got a really good deal on it. At or near like price to an A-2 for an A-1 is too much.
