Shaen for sure. Sending him a blank to get cut for an origin prefit today. Communication is second to none, a few quick texts and we had the whole thing planned out in under 20 min. Sounds like his usual turnaround time is about two weeks and from what I’ve seen, his work is second to none. Plus I like supporting a CA guy. It’s a tough state to make a living in the gun industry.
Bunch of good ones mentioned. I can personally recommend Jim Kobe, Redneck, Pete Peiper, David Christman, Jon Beanlanmd, Mike Bryant, and Karl Feldkamp. I've only used Karl lately for octagon barrels and fluting, but I'll bet he still chambers them.
+1 for Matt Stewart of Stewart Rifles. Builds a very nice accurate rifle and easy to work with. Super happy with the 7-08 he built for me. Robert Gradous had highly recommended him to me when Robert wasn't accepting any new work.
