i'm a new ar-15 owner and this is my 1st post on the board.

i'm looking for sights that i can use for 600m shooting.  the sight must have elevation and windage knobs and preferably a bullet drop compensator for variable distances.  i would also prefer it to have an illumination option for me to use in low light situations.  

here's the catch.  i only have about $450 that i can spend on these sights and i would prefer that to include the mounting bracket neccessary for me to mount it to my A2 bushy.

any and all help in pointing me to the right scope/sight to fit my needs is appreciated.

thanks in advance,

It costs $500 with the included carry handle mount.

that would put me around $1,500.  waaaay out of my price range.

Naw, you can find gently used Elcan all over for under $500.
