Granted, all bayou did for me was cut down a barrel and re-chamfer the muzzle, but I was impressed w/ quality of work. Rifle was dead on sighted in for 100 yds when I picked it up 3 days later.
Not threading a barrel, but I'd trust him to do it anyway.
He has a few guys working for him that might not be quite as educated when it comes to machining, which would account for the botch jobs, I guess.
