This is the Colt 6940, with full rail and flip front sight base, detachable rear sight, approximately 250 rounds through it. I shot a three gun match with this and had zero malfunctions. Gun comes with box, manual, all the accessories that came with it new (cleaning gear, etc). Two 20 round mags. There are a couple marks on the gun, so I have detailed pictures. One on top near the charging handle, one just rear of the trigger, and the other on the receiver just below where the lower meets the upper.
USPS shipped and insured.
