ONLY trades i would accept are a GEN 5 GLOCK 19 mos ($450-550 value) PLUS cash! Have a prolly 80% “clone correct” 14.5” URGI upper i built out myself. Colt “13629” marked upper receiver, colt socom profile “13629 M P” marked barrel, geissele URGI NSN marked 13.5” MK16 rail and a PIN & WELDED FCD/revival defense 3P15 (plan b suppressor mounting system). It’s the closest you’re gonna find on here to “clone correct” other than not having a daniel defense 14.5” mid length barrel and it doesn’t have a surefire four prong. I have shot zero rounds out of this upper. I am in well over $1k on this upper. NO BCG or charging handle! $550
