Bartlein Barrel - SS, 6mm, B#8 Light Varmint, 13.75 Twist, 29'' Blank, 4 Groove

Bartlein Barrels specializes in single-point cut rifling, offering a range of premium barrels like the 6mm SS B#8 Light Varmint. Our barrels are designed for precision and minimal stress induction, making them ideal for various shooting applications.

Contour and Barrel Performance

The barrel's contour plays a significant role in its performance. Heavier contours tend to resist movement and wandering as the barrel heats up, aiding in maintaining accuracy. However, at Bartlein Barrels, our advanced single-point cut rifling technique minimizes stress, making the contour less critical than in button-made barrels.

Single-Point Cut Rifling Advantage

Single-point cut rifling is superior to button rifling, especially for lighter weight contours. It does not induce stress or negatively affect bore sizes, ensuring consistent accuracy even when the barrel is threaded for attachments like muzzle brakes or suppressors.

Fluting: Benefits and Considerations

Fluting a barrel has multiple benefits: it reduces weight, increases surface area for better cooling, and adds a unique aesthetic appeal. However, excessive fluting can potentially affect barrel harmonics and accuracy.

Choosing the Right Rifling

We offer various rifling styles, including 4-groove, 5R, and Conventional-5. The choice of rifling has minimal impact on accuracy or barrel life, as confirmed by feedback from ammunition and bullet manufacturers. The 5R rifling, in particular, has shown benefits in reducing bullet deformation and improving flight.
