Surplus CQBR Mod1 MK18 Upper Receiver Group assembled onto a new contract production upper receiver. The parts in this URG have seen action downrange and will show such but they are well within spec and have a ton of life left in them. These FN SOCOM barrels are virtually impossible to kill and not often seen on the commercial market.
Save some $$ and own a MK18 URG with way more cool points than a commercial Daniel Defense!
