When it comes to accuracy, reliability, toughness, the best-built rifles are the ones that are made specifically for you. We consolidate the union between operator and firearm with our custom rifle services. Our shop specializes in the machining and fitting of fully custom uppers--the portion of the rifle which accepts the barrel and its various operating components. 

By utilizing the latest technology and the leading names in firearms components, our gunsmiths build rifles according to your exacting specifications. We build both competition and tactical rifles. Simply tell us the rifle’s primary purpose, and we’ll take care of the rest. Our teams work with a variety of platforms, including the popular AR-pattern. Our selection of upper receivers includes:

Tactical and Varmint builds

Being out in the field also means needing an answer to the uncertainties that dwell within it. Whether your line of work involves law enforcement or protecting the ranch, we craft the tools you require to gain the advantage. Our workshop assembles purpose-built rifles according to your needs.

Many of our varmint-style and tactical builds include a 20” rifle barrel that may be fluted to reduce weight.

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."
