Bob-
Call John and speak with him. Ask about barrel choices. John probably has Kreigers and Pacnor's in stock, as well as Wilson's. His free float tube is the best on the market, and comes in about any color you could want, including camo!
You can buy any lower, but talk to John about his tweaked RRA trigger. JOhn takes the standard RRA National Match 2 stage trigger and cleans it up. SInce you don't have any weight limitations on trigger weight, have John set you one up for your varmint rifle. You will love John's trigger!.
Tell him some really strange guy from Houston, Tx, who babbled a lot about 6.5 twist PacNor barrels and JLK90s sent you!
