This barrel features M4-style feed ramps for enhanced reliability and consistent chambering, particularly under high-stress or high-volume firing conditions. The 14.7-inch length provides a compact, maneuverable profile while still maintaining effective ballistic performance. The midlength gas system delivers smoother cycling and reduced felt recoil compared to carbine-length setups, improving overall control and longevity of parts.
Finished in classic black manganese phosphate, the barrel is both rugged and professional in appearance. It is designed to fit all standard AR-15 platforms and is ideal for tactical builds, duty rifles, or performance-driven custom configurations.
