Vertiviper,You can also check out Model 1 Sales and see if they have any complete kits in stock.Depending on the type of barrel you want,they offer 1-7,1-8,1-9 twist in their 5.56/223 barrels.They will build whatever combo of parts that you want for decent prices. I have bought from them for several years,and they are good to deal with. The last one I bought from them was a 16" stainless heavy barrel 1-8 twist flat top upper,and it shoots great.
