WTS: 16" Stainless 5.56m barrel

[Dorty]

I have a stainless steel 16" barrel in 5.56m with a 1/8 twist rate for my AR that I am looking to sell.. it came in a completed upper from Model1Sales, and has the M1S stamps on it. From what I know they use ER Shaw barrels for their upper kits. I have put approx. 100 rounds through it, and it shoots good. A friend of mine just offer to sell me his barrel so I have no need for it. I am asking $200 for it but am willing to negotiate. Thanks
