WTB Barrel

My son is due to get out of the Army on June 14. As a welcome home gift, I am piecing together some parts so we can put a rifle together when he gets home. I am looking for a 16" barrel in 5.56. I don't need anything special, but I would prefer something better than a BCA. I live in Denton and work in Irving. I would meet somewhere in between or within reason. I also travel to Young county frequently. I'd be glad to pay for shipping on the right deal. TIA!!!
