Bartlein Barrel - Advanced Precision for Shooting Enthusiasts

Bartlein Barrel SS 6mm B#14 M24: Unparalleled Precision in Rifle Barrels

Impact of Barrel Contours on Weight and Performance

Understanding the impact of barrel contours is crucial for shooting accuracy. Heavier contours offer stability and resist movement as the barrel heats up, essential for maintaining consistent shot groups.

The Bartlein Difference: Single Point Cut Rifling

At Bartlein Barrels, we specialize in single point cut rifling, a process that does not induce stress into the barrel blank, contrasting with button rifled barrels. This technique ensures that contour selection is less critical while maintaining high accuracy.

Advantages of Heavier Contours and the Role of Suppressors

Heavier gun barrels typically offer better performance due to improved recoil handling and reduced fatigue for the shooter. However, lighter weight contours can perform equally well. When using a suppressor, a medium palma contour or larger is recommended to ensure optimal harmonic vibrations.

The Superiority of 5R Rifling

5R rifling, unique to Bartlein Barrels, offers enhanced bullet flight and reduced bullet failure. This is attributed to the gentler angle on the lands, less distortion to the bullet jacket, and the odd number of lands in the bore, which do not directly oppose each other.

Why Fluting Matters in Barrels

Fluting a barrel provides several benefits, including weight reduction, improved barrel cooling due to increased surface area, and aesthetic appeal. However, excessive fluting can lead to harmonic and vibration issues, potentially affecting accuracy.

Rifling Styles and Their Impact

Bartlein offers 4-groove, 5R, and Conventional-5 rifling styles, each with unique benefits. The 5R rifling is particularly effective for long-range shooting and minimizing bullet deformation.


The Bartlein SS 6mm B#14 M24 Barrel with 8 twist and 5R rifling represents the pinnacle of shooting precision. Its design and manufacturing process cater to the needs of both competitive and recreational shooters seeking the highest level of accuracy and performance.
