Description

This 10.5 inch barrel is constructed from 4150 Chromoly Steel, providing a durable foundation for custom AR-15 builds. The barrel features a .750 diameter gas block area, which is essential for ensuring proper gas system alignment in compact platforms. It is chambered in 5.56/.223 Caliber, allowing for versatile ammunition selection within the standard 5.56×45 specification. The internal rifling utilizes 1:7 Twist rate, a specification that stabilizes heavier bullet weights commonly used in tactical applications.

This barrel utilizes a Carbine Length Gas System, which is optimized for the 10.5 inch length to maintain proper gas pressure and cycling. The solid contour profile helps manage heat distribution while keeping the overall weight manageable for handheld platforms. It is designed for builders who require precise specifications for custom AR-15 builds, ensuring compatibility with standard components. The combination of 4150 steel construction and black Nitride finish provides a balance of durability and aesthetic consistency for tactical or competition builds.
