I currently have a Colt Post Ban AR-15, with the A2 upper. I would like to add a scope to it, but don't like the height that the A2 adds. I was wondering whether I should, 1. Buy a totally new AR with flattop upper. 2. Buy a new upper and fit it to the lower, or 3. Just buy a flattop receiver and put it on the rifle? Also tell me your reasoning behind your choice. Thanks ahead of time for any advice.
