I've had Mike do a fair amount of work for me over the years.
Always fast and well done but I think that barrel bore work and stock bending are his specialties and he makes no secret of that.
I had him install a recoil pad on a gun once and re-blue the barrels and I don't recall it taking a long time. I sent a gun to Rich Cole once for re-blueing and I thought I'd never get them back. Rust blueing is often done in an outdoor tank because it's quite toxic and it doesn't work in the wintertime so a lot of gunsmiths in the colder states have to wait for warm weather. Even then, it's a nasty job and best done after accumulating a few sets to do all at once. I would expect a long wait for a rust blueing job from anyone. I did send a gun to Mike to have the stock bent and when he didn't return it very soon, I called him and asked what was up. He told me that he didn't believe that particular stock could be bent without breaking and he returned the gun at no cost to me. Not even shipping.
I have always considered him to be very fair and wouldn't hesitate to use him again. I've used him about half a dozen times I would guess.
