I left the gun show today with a DPMS complete lower with a collapsible stock that I got for $250 with tax. Now I need an upper assembly of course. I just have no idea which to get. I only have a few preferences which are a 16" barrel, detachable carry handle and sights so I can later switch things up a little, and I don't want to break the bank. I'll be using the rifle for target shooting at 100-150 yards for the most part. Things like a free floating hand guard and chrome lined barrel would be nice but not sure if they will fit into the budget which is a maximum of $500 for everything else. Any help will be greatly appreciated.
