Bartlein Barrel - SS, 6mm, B#8 Light Varmint, 13.5 Twist, 29'' Blank, 5 Groove

Discover the precision of the Bartlein Barrel 6mm B#8 Light Varmint, a superior choice for competitive shooters and custom rifle builders. Bartlein Barrels, known for their meticulous craftsmanship, offers this barrel with a unique combination of features to enhance your shooting accuracy and consistency.

Contour and Barrel Weight

The contour of the barrel plays a significant role in its weight, impacting the rifle's balance and handling. While heavier contours can provide stability and reduce barrel movement as it heats up, Bartlein Barrels' advanced single point cut rifling technique minimizes residual stress, making contour selection less critical compared to traditional button rifled barrels.

Single Point Cut Rifling

Bartlein Barrels utilizes the single point cut rifling process, renowned for producing barrels with almost perfect concentricity and uniform twist rates. This method induces no stress into the steel, ensuring long-lasting accuracy and performance.

Fluting for Enhanced Performance

Fluting not only adds a unique aesthetic to the barrel but also reduces weight and improves barrel cooling. While fluting depth is crucial to maintaining the barrel's harmonic characteristics, Bartlein Barrels ensures the perfect balance between aesthetics and functionality.

Rifling Styles and Benefits

Offering three types of rifling - 4-groove, 5R, and Conventional-5 - Bartlein Barrels caters to diverse shooting needs. The 5R rifling style, in particular, is known for reducing bullet deformation and failure, enhancing the bullet's flight and accuracy, especially in specific shooting disciplines.
