Daniel defense 18in 5.56 / 223 ar barrel

I have a near new ar barrel that is a 5.56/223 Daniel Defense 18" s2w CHF 1-7 twist with a rifle length gas system. Comes with a Daniel defense low profile gas block and two rifle length gas tubes.  I'm looking to get $480 shipped . Barrel has had only one box of ammo used through it. 

TRADES I'm interested in are SMLE Lee Enfield must have the full wood and be in good condition with good bore, vz58 5.56 magazines and parts
