Many people also report not being able to see the front sight post at 3x magnification even.
^^What he said.
I can confirm that the front sight post does not interfere with my 3x9 Leupold scope mounted on my 15 Sport.

Just to build a little on what's been said already about wanting and ACOG...
ACOG is a scope made by Trijicon. The run $1000 and up. What it is, generally, is a fixed 4x32 scope with an illuminated reticle. A 4x32 scope with illuminated reticle can be found much cheaper. It won't be as good, but you can get that look and those features in the budget you mention.
Like this, for example:

Good luck! picking an optic is sometimes the hardest thing to decide on
Just concerned about the front sight getting in the way honestly. I know I see a lot of scopes mounted on the carry handle, but is that really effective?

This is the one I have my eye on at the moment
