Gunsmithing SE Michigan: Gunsmith

Not 100% sure where exactly you're at in SE MI but Williams Gunsight in Davison by Flint is a good option for a lot of guys over there. If you don't mind shipping it in state then I would highly recommend sending it to Justin @ Precision Rifle Company / Spinners in Dorr, MI (south of GR a little ways). He builds and works on all of my rifles now and does top notch work with fast turn around! Shoot me a PM if you want his contact info.
 
Yea I've never had them work on one of my rifles personally, but I have bought a 257 Roberts and a 223 that were built by them and they are both hammers so I have no doubt that they do good work.
 
I am also located in SE MI and had area 419 do some work, before that i used pierce eng in lansing. Both have done a fine job, but my go to would be area419. heard good things about spinners in GR but never had anything done there yet.
