Just for giggles, I want to sell this DMPS 16” Upper ($485 shipped) so I can build a new 18” SPR. I purchased this upper new, and have only fired the recommended break-in rounds. (25) with a barrel cleaning after each shot. Upper is in perfect condition, marked 5.56 1 in 9 barrel, and manufactured by DPMS. Comes as pictured from the stock photo below. If you want a black MOE handguard add $25. If you want a FOBUS integrated lower picatinny rail handguard add $40 A link to the DPMS page that describes the upper: http://www.dpmsinc.com/store/products/?prod=1769&cat=1646 Photos of the additional parts.
