The only reason this is in the used department is that it has been mounted and handled, action cycled, but never fired
Upper receiver marked "C" "M" in front of rear sight.
FSB marked with a diamond "B5"
BBL marked "C MP 5.56 NATO 1/7"
No Handguards (See my ad for Surefire system that was on it)
Slight rub marks on FH flats, and a very small pin head sized shiney spot from handling (Rear of Shell deflector), very slight edge rubs on top of carry handle. These are the only marks outside the mounting surfaces that I can find.Contact by email please
