Note From the Gunsmith About Pricing

"Price range will vary a great deal depending on the type of barrel requested. I use all of the well-known barrel producers and will use whatever barrel the customer is most comfortable with. If you are unsure of what type of barrel you are after, please feel free to call to discuss. Typically, premium single point cut rifle barrels are more expensive and may require longer wait times. However, I would like to emphasize the fact that there are many excellent button rifle barrel manufacturers who produce barrels capable of extreme match winning accuracy. I know this from some considerable experience and would be happy to share what I know so that you may make a better decision."
