Experience Precision with Bartlein's SS 6mm B#9 Heavy Varmint Barrel

Introducing the Bartlein Barrel - a masterpiece in precision shooting.

The Bartlein Difference: Precision and Performance

At Bartlein Barrels, we understand the critical role of barrel quality in shooting accuracy. That's why we employ single point cut rifling in our manufacturing process, ensuring zero stress induction into the barrel blank. This meticulous approach results in barrels that deliver consistent, precise shots without the wandering groups observed in barrels with residual stress.

Understanding Barrel Contours

Does contour affect barrel performance? Absolutely. Heavier contours can improve shot stability by resisting movement as the barrel heats up, enhancing accuracy over extended shooting sessions. However, Bartlein's advanced manufacturing techniques mean contour becomes less critical, allowing for excellent performance across various weights and designs.

Suppressor Compatibility and Harmonic Precision

Choosing the right contour for suppressor use is crucial. A heavier barrel optimally supports the added weight of a suppressor, minimizing impact on harmonic vibrations and maintaining accuracy. Bartlein recommends a medium palma contour or larger for suppressor attachment, ensuring your shooting precision remains uncompromised.

Why Choose Single Point Cut Rifling?

Single point cut rifling stands out for its precision. Unlike button rifling, which can introduce stress and affect bore dimensions, our method ensures impeccable bore and groove concentricity, maintaining uniformity and accuracy even after contouring or muzzle threading.

The Art of Barrel Fluting

Fluting is not just about aesthetics; it's a strategic choice for weight reduction, enhanced cooling, and improved barrel performance. While too deep fluting can affect harmonics, Bartlein maintains optimal depth to ensure accuracy is never compromised.

Choosing the Right Rifling

With options like 4-groove, 5R, and Conventional-5 rifling, Bartlein offers versatility without sacrificing quality. Our experience shows that rifling style has minimal impact on accuracy or barrel life, with 5R rifling providing additional benefits in bullet integrity and flight thanks to its unique design.
