Colt M4A1 Block2 upper
Please text for the quickest reply.
This is a new and unused Colt 6920 OEM2 upper (cage code, square forge). It uses the low pro front sight gas block that was chopped and installed by Colt. D. Wilson Mfg cut the 16″ barrel to 14.5″ and pinned the Surefire 4 Prong muzzle device. The Daniel Defense RIS2 M4A1 rail that was installed was also factory new and unused. No bolt or charging handle is included. I have Colt factory GI charging handles, PRI Gas Buster, Geissele charging handles and more if you are interested. Please add $5 to ship.
