With the tell-tale "C" stamps on its 16" SOCOM profile barrel, upper receiver and M-16 bolt carrier, there is no doubt about the quality or the heritage of this Colt factory upper. That quality and heritage are both further reinforced with the addition of top shelf, truly milspec components and accessories. These include the tried and true MaTech 600m BUIS, Troy Industries quad rail with four anti-rotation QD sockets, aluminum Delta Ring Assembly, Magnetic Particle Inspected(MPI) marked bolt, and dry film lubricated upper receiver. So whether it is a day at the range, or a day down range, this complete Colt 6920 SOCOM "M4A1" upper is up to the task.
