Colt sp1 upper 20 inch pencil barrel. Barrel marked C MP Chrome Bore.
Front sight is marked with a C, below that forward of the gas tube is an M
inside a bell. Receiver is marked C and M below the rear sight.
Has a flat delta ring and I believe colt made triangle hand guards.
Large front pin, NO shell deflector or forward assist.
Looking to sale for 280.00 shipped or trade for a pistol caliber upper that is
RRA/Colt style. If looking to trade uppers and you have a bolt and carrier
then I can trade a spare RRA Enhanced bolt and carrier. If you also have a
mag block and mags that you can part with we can work out prices on
those items. Crappy pics below
