Zack was recommended to me by SWRS here in the thread a few weeks ago.. He is currently working on a 6BR build for me. I was so impressed with my initial experience with him that instead of sending a new Rem 700 5R .308 back to Rem due to a chamber issue I forfeited the warranty and sent it to Zack to allow him to re-barrel it. I feel it will be a much better rifle in all perameters with him doing the work than Rem could possibly do.
