Wanting to trade my PSA 14.5 inch light profile P&W upper with Primary Arms GLx 2x prism sight for a carry handle 16 (or 14.5 P&W) upper. My upper is complete with BCG and charging handle. I will keep them if you don't want to swap yours. I can change the sight to a Burris RT-3 if preferred
The upper was on a KE Arms KP-15 lower, I've gone to a KE Arms WWSD Civil Defense upper. The sight doesn't work for the type of shooting I wanted to use it for. My eyes don't work with any magnification when shooting with both open. I went to a Gideon Advocate 1X micro prism sight.
