Bartlein Barrels - Precision SS 6.5mm Medium Palma Barrel

Bartlein SS 6.5mm B#11 Medium Palma Barrel: A Benchmark in Precision Engineering

Welcome to Bartlein Barrels, where our SS 6.5mm B#11 Medium Palma barrel with an 8.5 twist and 5R rifling sets new standards for precision and performance. Crafted for the discerning shooter, our barrels are designed to provide superior accuracy and longevity, ensuring your shooting experience is unmatched.

Unrivaled Precision with Single Point Cut Rifling

At Bartlein Barrels, we employ single point cut rifling, a method that ensures no stress is induced into the barrel blank. This process not only enhances the barrel's accuracy but also its durability, making our barrels a preferred choice for competitive shooters and enthusiasts alike.

Contour and Performance: Finding the Balance

Understanding the balance between barrel contour and performance is crucial. While heavier contours can provide stability and reduce wandering shots as the barrel heats, our advanced manufacturing techniques mean that even lighter contours deliver exceptional performance, negating the need for undue concern over barrel weight.

Suppressor Compatibility and Harmonics

Using a suppressor? Our barrels are designed to accommodate. Heavier barrels tend to perform better with suppressors attached, minimizing harmonic disruption and maintaining accuracy. Our recommendation? Opt for no less than a medium palma contour to ensure optimal performance when using suppressors.

The Importance of Barrel Fluting

Fluting isn't just about aesthetics; it plays a critical role in reducing weight, enhancing barrel cooling, and maintaining stiffness. While deep fluting can affect harmonics, we carefully balance depth to ensure accuracy is uncompromised, offering you the best in both performance and design.

Rifling that Redefines Accuracy: The 5R Advantage

Choosing the right rifling is pivotal. Our 5R rifling, with its gentler land-to-groove transition, minimizes bullet deformation, enhancing accuracy and reducing the likelihood of bullet failure. This innovative design, coupled with feedback from ammunition and bullet manufacturers, confirms the superiority of 5R rifling in improving bullet flight and overall barrel performance.

Whether you're a competitive shooter, a hunting aficionado, or a precision enthusiast, the Bartlein SS 6.5mm B#11 Medium Palma Barrel with 5R rifling is engineered to elevate your shooting prowess. Experience the Bartlein difference today and redefine your expectations of barrel performance.
