Features

Our introduction of a bolt action barrel blank has expanded the possibilities for adapting your preferred caliber and accommodating various actions. Within our selection of bolt action barrels, you'll find a spectrum of options, including different calibers, lengths, profiles and rifling twist rates. Your bolt action barrel will arrive ready for threading and chamberings by your chosen gunsmith. It's important to bear In mind that while proof Research's barrel blanks can be customized with different chambers, we cannot guarantee specific performance metrics such as accuracy, muzzle velocity and bullet stability. This is especially relevant for wildcat cartridges without standardized chambers, designs or pressure specifications. While proof Research's barrels are engineered for secure operation with most established cartridges and within SAAMI and CIP pressure limits, we recommend caution for unique rifle builds. If you have questions about safety or the potential performance of your intended rifle assembly, please reach out to our customer service department.
