The Je Machine Tech PS-BAL25 AR-15 Barrel 10.5" 9mm is a compact, dedicated 9mm barrel built for AR-15 pattern builds that need a shorter profile without giving up reliability. Precision machined from 4150 chrome moly steel and finished in black nitride, it offers a clean look with corrosion resistance and long service life. The barrel is clearly marked "9MM 1:10" on the shank, confirming its twist rate for consistent performance with common 9mm loads.

This 10.5 inch 9mm barrel is well suited for pistol-caliber carbines, AR pistols, and range-focused builds where maneuverability and balance matter. The 1:10 twist rate is optimized for typical 9mm bullet weights, making it a solid option for training, recreational shooting, or building a dedicated 9mm upper. Backed by Je Machine Tech’s reputation for practical, value-driven components, it provides a straightforward path to a reliable 9mm AR-15 configuration.
