We've expanded the possibilities for adapting your preferred caliber and accommodating various actions with our bolt action barrel blanks. Our barrels come In different calibers, lengths, profiles and rifling twist rates. Your chosen gunsmith can thread and chamber your bolt action barrel upon delivery. It's important to understand that while we can customize our barrel blanks with different chambers, we can't guarantee specific performance metrics like accuracy, muzzle velocity or bullet stability. This is especially relevant for wildcat cartridges without standardized chambers, designs or pressure specifications. While our barrels are designed to operate safely with most established cartridges within SAAMI and CIP pressure thresholds, caution is advised for unique rifle builds. For safety or performance inquiries regarding your intended rifle assembly, please contact our customer service department.
