You have quite a few good options on the west side.
Ken Hagen - H&H Precision Rifles 253-293-8983 hprecision@comcast.net - Ken knows how to build some VERY ACCURATE rifles. Good guy also.
Benchmark Barrels - 360-652-2594 benchmarkbarrels@gmail.com - These guys do some gunsmithing work. But they make some of the best barrels out there. I have been shooting their barrels for roughly 5 years now, and have nothing but top marks to say about them. I took around 60th place out of 240 of the best international shooters at the Snipershide Cup in Colorado this year, using one of their barrels.
