Cook's Guns... anyone do business with them?

There is a "cook's gun's" in the Springs. Silencer shop seems to recommend them. I've never heard of them... Has anyone ever done business with them?

I know Jim Cook personally; used to go to the same church as him and he was one of my ushers/servers when I ran that ministry. While I can say that he's a good man (although looks grumpy), I don't know anything about his gunsmithing abilities or services.

I have dealt with him. He did a barrel pin replacement and welded the rear bend on an RPK that split for me.
His work was good and turn around was quick. I was happy.
He is at some of the guns shows from time to time.....yes he looks grumpy!
I tried to see if he could do another job but he was booked up for awhile.
I would use him again.
