I am currently in the process of building an AR-15. I live in chattanooga TN, and have been able to get all the parts for the lower in town, and have recently put them together. I am in need of an upper, I am wanting to buy a complete upper that comes with the barrel, and bolt and carrier. Does anyone know where I can find a complete upper for around $400? I am looking at spending that but anything around 300 to 350 would be great. I am new here I joined to see if anyone could help me out. If you know of any websites with them for cheap please send the link to me. I would prefer to buy locally but there are no gun shows until september, and I do not want to wait that long to fire this gun. If you know anywhere that I can find them let me know.
