Premium Craftsmanship for Serious Shooters

Bartlein Barrels, a leader in the precision barrel manufacturing industry, offers the .338 Cal B# Custom barrel, a testament to our unwavering commitment to quality. Engineered for superior performance, this barrel features a 10 twist and a 33'' blank, ideal for custom rifle builders and competitive shooters demanding the utmost in accuracy and reliability.

The Bartlein Advantage: Single-Point Cut Rifling and 5R Technology

Unlike conventional button-rifled barrels, every Bartlein barrel benefits from single-point cut rifling, ensuring no stress is induced into the barrel blank. This precision process guarantees a perfectly concentric barrel, crucial for achieving consistent accuracy. Furthermore, our adoption of 5R rifling not only enhances bullet stability but also minimizes bullet deformation, significantly improving shot performance.

Understanding Barrel Contour and Performance

At Bartlein Barrels, we recognize the impact of barrel contour on weight and performance. Heavier contours provide stability and reduce barrel movement as temperatures rise, offering an advantage in precision shooting. However, our expertise in barrel design ensures that even lighter contours achieve exceptional performance, challenging the notion that heavier always means better.

Optimized for Versatility and Aesthetics

Whether equipping your barrel with a suppressor or considering fluting for aesthetic and functional benefits, Bartlein Barrels accommodates diverse shooting styles and preferences. Our barrels are designed to support various attachments without compromising on performance, and our fluting options not only reduce weight but also enhance barrel cooling and provide a distinct look to your rifle.
