Bartlein Barrel SS 5.56mm, B#11 Medium Palma: A Synthesis of Precision and Durability

Introducing the Bartlein Barrel SS 5.56mm, a masterpiece in precision firearm manufacturing. The B#11 Medium Palma design, coupled with a 7.75 twist and a 31'' blank, makes this barrel a top choice for shooting enthusiasts who seek unparalleled performance and accuracy.

Impact of Barrel Contours on Performance

The contour of a barrel plays a crucial role in its weight and shooting dynamics. The Medium Palma contour of the Bartlein Barrel offers a perfect balance, enhancing stability and accuracy, especially when the barrel heats up during shooting.

Superiority of Single Point Cut Rifling

At Bartlein Barrels, we specialize in single point cut rifling, a process that ensures minimal stress on the barrel blank. This technique provides a consistent and precise bore size, unlike button rifling, which can introduce significant stress and affect barrel performance.

Optimizing Barrels for Suppressors

Not all barrel contours are suitable for suppressor use. Our Medium Palma contour is designed to accommodate suppressors effectively, ensuring that the harmonic vibrations of the barrel are not adversely affected, which is crucial for maintaining accuracy.

The Art of Fluting a Barrel

Fluting is more than an aesthetic enhancement; it plays a significant role in barrel performance. By reducing weight and increasing surface area, fluting improves barrel cooling and can impact barrel harmonics. We carefully consider the depth of fluting to avoid any negative effects on accuracy.

Choosing the Right Rifling for Your Shooting Needs

The Bartlein Barrel offers various rifling options, including the advanced 5R rifling. This style is designed to reduce bullet deformation and improve flight, essential for achieving precise and consistent shots. The 5R rifling is particularly effective in reducing bullet jacket distortion, enhancing overall shooting performance.

Why Choose Bartlein Barrel's 5R Rifling?

The 5R rifling in our barrels represents our commitment to precision and quality. This rifling style has been shown to enhance bullet flight, as evidenced by feedback from ammunition and bullet manufacturers. It stands out as an excellent choice for a range of shooting applications, from competitive to recreational use.
