One of the first problems I ran into with my AR was the lack of room available for operating the charging handle if a scope was mounted. To fix this issues, I ordered a couple of these Ambidextrous Extended Levers for my charging handle.
They are actually quite easy to install and do work remarkably well for the inexpensive price. I paid less than $10 per lever to include shipping.All you do is drive the pin out of the charging handle latch and then swap out the lever. It takes only a couple of minutes and looks like this after installation.

Oops
I do recommend these charging handle latches for if you need a little extra room due to optics or bear paws for hands.
