Do you have a vintage 12 gauge shotgun that is short chambered? “Short chambered” means the chambers are for 2 5/8″ or shorter shot shells. We offer this service for double or single barrel shotguns. Price is $100 per barrel. Rechambering involves lengthening the chamber to 2 3/4″, then lengthening the forcing cone and finally honing the transition. This is done by our professional on site gunsmiths. We will need your complete shotgun for this conversion for test firing. Please give our shop a call to discuss the conversion price and to answer any of your questions.
