I picked this up last fall.
Factory Colt MK18 barrel. It is new but somebody put some marks on it when they removed the side sling mount.
It has the gas tube, barrel nut, and FSB which is factory installed. It has a regular A2 flash hider that was installed at Colt.
It has been mounted into a receiver but never fired. It is not a cut down, but a factory Colt 10.3" length.
No other issues. When was the last time you saw this for sale?
This is not the same barrel that SAW lists as a “MK18 barrel”. Those are modified M4 barrels.
This is the real deal.
I would like $500 for this.
