Bartlein Stainless Steel 7mm Barrel: Mastery in Precision Engineering
Impact of Barrel Contours on Performance
Barrel weight is significantly influenced by its contour. Heavier barrels tend to perform better under thermal stress, maintaining accuracy as temperatures rise. Bartlein Barrels leverages single point cut rifling to minimize stress in the barrel blank, making contour choice less critical for our precision-crafted barrels.
Suppression Compatibility and Shooting Accuracy
Utilizing suppressors on heavier barrels can enhance shooting performance by stabilizing harmonic vibrations. Bartlein recommends against equipping suppressors on lighter contours than a medium palma to maintain optimal harmonic balance and precision.
Single Point Cut Rifling vs. Button Rifling
Single point cut rifling, a hallmark of Bartlein Barrels, ensures unparalleled accuracy by eliminating the stress typically introduced during the rifling process. This method guarantees a consistent bore size and eliminates the risk of bore expansion during muzzle threading, a common issue with button rifling.
Benefits of Barrel Fluting
Fluting a barrel reduces weight while enhancing cooling efficiency and aesthetics without compromising stiffness. Bartlein meticulously designs fluting to ensure it adds to the barrel's functionality and appearance, providing a harmonious balance between form and function.
Choosing the Optimal Rifling Style
Bartlein offers a selection of rifling styles, including 4-groove, 5R, and Conventional-5, catering to different shooting preferences. The 5R rifling, in particular, minimizes bullet deformation, improving bullet flight and accuracy.
The Bartlein Advantage
Bartlein Barrels stands at the forefront of barrel manufacturing, combining advanced rifling techniques with precision engineering to offer shooters unmatched performance. Choose Bartlein for a barrel that elevates your precision shooting experience.
