Our Custom Pre-fit Configurator allows you to build a pre-fit barrel to your exact specifications. Similar to our Custom Barrel Blank Configurator, you are able to build every aspect of the barrel from breech to muzzle. Choose from a wide range of over 70 custom and production actions, and build the pre-fit barrel that suits your unique application.

Select a caliber option - ranging from .20 to .338 - with a proven twist rate to suit your needs. Complete your pre-fit by selecting your muzzle thread, crown, and finish options.

Whether you are building your next match winning competition rifle, trustworthy hunting rig, or precision tactical build, our pre-fit barrels will provide you with the foundation of your next rifle.

Production Actions (requires barrel nut)

Due to the mass-produced nature and loose tolerances of production actions, headspace cannot be guaranteed with a shouldered barrel. Production actions require the use of a barrel nut to guarantee proper headspace.
