Bartlein Barrels: Precision Rifled for Optimal Performance

Discover Precision with Bartlein Barrels

Unmatched Quality for Serious Shooters

Bartlein Barrels, renowned for their precision single-point cut-rifled barrels, caters to the elite needs of competitive shooters and custom rifle builders. Our SS 5.56mm B#11 Medium Palma barrel with an 8 twist and a 31'' blank is a testament to our commitment to excellence, designed to deliver unmatched performance and accuracy.

Why Choose Bartlein Barrels?

Our barrels are meticulously crafted to ensure superior performance, from reducing residual stress common in button-made barrels to enhancing shooting precision with our unique 5R rifling. The 5R rifling not only improves bullet flight but also significantly reduces bullet deformation, providing a clear advantage in precision shooting.

The Importance of Barrel Contour and Rifling

At Bartlein Barrels, we understand the critical role of barrel contour and rifling in shooting performance. Our barrels, featuring the Medium Palma contour and 5R rifling, offer an optimal balance between weight and stability, ensuring minimal barrel movement and consistent accuracy, even under the rigorous conditions of competitive shooting.

Advanced Features for Enhanced Performance

  • Superior Steel Quality: Our barrels are crafted from steel that meets our rigorous specifications, ensuring durability and performance.
  • Single-Point Cut Rifling: This method ensures almost perfect concentricity and uniform twist rates, enhancing barrel longevity and shooting accuracy.
  • 5R Rifling: Offers improved bullet stability and reduced deformation, enhancing both accuracy and bullet performance.
  • Fluting Options: While not essential, fluting can reduce weight, improve barrel cooling, and add a unique aesthetic to your rifle.

Customization and Compatibility

Whether you're involved in competition shooting, hunting, or tactical applications, our barrels are customizable to meet a wide range of specifications, including contour, length, and rifling, to fit your precise shooting needs.


Choosing a Bartlein Barrel means investing in a legacy of precision and quality. With decades of experience and a relentless pursuit of perfection, our barrels are engineered to elevate your shooting performance.
