A few weeks ago, I came accross a guy, on a forum, who would put a screw-in choke system (either Rem choke or Tru choke)on your shotgun barrel for, I think $55.00. Does anyone know of this guy. I cant locate him now. Thanks

Possibly Mike Orlen in Amherst Mass ? He's done 3 bbls for me, though his prices are a bit more than $55.00
