Hi, to start off, the upper is brand new, never used. I'm only listing it as used because I did accept delivery from psa and also the Knight's Armament accessories is used. It is a carbine PSA 16" m4 profile upper with the cold hammer forged barrel (zero rounds through it), no bcg or ch. Installed on it is a genuine kac ras rail, 3 kac rail panels, kac vertical grip and a matech buis. I hate to sell it as this was going to be the beginning of my sopmod block 1 build, but I have a new baby and priorities take precedence. Asking $325 shipped. I could send pics when I get home after work. However the first one that post I'll take it and pays gets it. I accept PayPal discreet or you pay fee.
