This is a clone correct, Black Creek marked mk18 upper. It has a Colt Cage code (13629) marked upper, Black Creek marked DD RIS II rail, and a Colt 10.3" barrel. It has a Surefire 4-prong flash hider, Colt C-marked BCG, Mk12 gas block, and a milspec charging handle. It does come complete with all the above.
This upper has obviously been used and has some wear and tear, but is completely functional and honestly I prefer the "patina" look. The barrel is clean and has great rifling but unfortunately I don't have a borescope or anything to post videos of with.
Strongly prefer local meet-ups and I am not interested in trades at this time.
