Bartlein Barrels: Precision SS 5.56mm B#12 Heavy Palma Barrel with 5R Rifling

Unveiling Bartlein Barrels' SS 5.56mm B#12 Heavy Palma with 5R Rifling

Introducing the Bartlein Barrel - SS, 5.56mm, B#12 Heavy Palma, 8 twist, 30'' blank, 5R, a testament to cutting-edge barrel manufacturing designed for precision shooters seeking unmatched accuracy. At Bartlein Barrels, we understand that every detail, from contour to rifling, plays a crucial role in shooting performance.

Impact of Barrel Contour on Performance

Barrel weight is significantly influenced by its contour. A heavier contour can mitigate shot wandering caused by residual stress, especially in barrels subjected to intense heat. Bartlein Barrels, specializing in single point cut rifling, minimizes this stress, thus reducing the dependency on heavier contours for consistent accuracy.

Advantages of Heavier and Lighter Contours

While heavier barrels traditionally offer better shooting stability due to reduced recoil and fatigue, Bartlein's advanced manufacturing techniques show that lighter contours can perform just as effectively. This demonstrates that contour selection should be tailored to the shooter's specific needs rather than conventional wisdom.

Suppressor Compatibility and Barrel Contour

Suppressors perform best on heavier barrels due to their influence on harmonic vibrations. Bartlein recommends using suppressors with no less than a medium Palma contour to ensure optimal performance and accuracy.

Superiority of Single Point Cut Rifling

Bartlein's single point cut rifling stands superior to button rifling by eliminating induced stress, allowing for smaller contours without compromising bore integrity. This technique ensures consistent accuracy, especially when modifying the barrel for attachments like muzzle brakes or suppressors.

Benefits of Barrel Fluting

  • Weight Reduction: Fluting removes material without compromising the barrel's structural integrity.
  • Improved Cooling: Increased surface area from fluting enhances heat dissipation.
  • Aesthetic Appeal: Many shooters choose fluting for its distinctive appearance.

Choosing the Right Rifling

Bartlein offers 4-groove, 5R, and Conventional-5 rifling, with each type providing unique benefits. The 5R rifling, in particular, is known for reducing bullet deformation and improving bullet flight, which can significantly enhance shooting accuracy.

Conclusion

The Bartlein SS 5.56mm B#12 Heavy Palma barrel with 5R rifling represents the pinnacle of barrel design, offering shooters a significant edge in accuracy and performance. Whether you're a competitive shooter or a hunting enthusiast, this barrel is engineered to meet the highest standards of precision and durability.
