We have a variety of barrel blanks in stock and in most cases we can contour them to your specifications in a week or two. If you want a caliber/twist rate that is not shown in some cases we will be able to order it for you but delivery times vary from 6-8 weeks for Douglas and Shilen to 6 months or more for the other barrel makers.
Contoured barrels typically have a 1" shank suitable for most single shot rifles, so if you want something larger you must let us know. We can generally accommodate custom contours, but there may be an extra charge.
Contoured barrels are polished and ready to blue. If you want it unpolished make a note and the price will be somewhat lower.
