Sounds like a great build in the works. From what I've read people review the 20" Rainier Ultra match barrel really well and it can give sub MOA accuracy. I went with a 18" select barrel because I mainly do bench shooting and wanted a budget build. If I feel the need in the future I will upgrade to the Ultra match.
