This button-rifled barrel features a medium contour profile, 1/2 x 28 threading, 5RM4 feed ramps, and an 11 degree target crown, making it an excellent choice for completing an AR build or as a replacement barrel for existing rifles.
With its mid-length gas system and medium contour, this .223 Wylde barrel represents modern barrel engineering. The 4150 Chrome Moly steel with black nitride finish and button rifling deliver a traditional 11-degree target crown. The mid-length gas system provides balanced cycling and reduced recoil impulse compared to carbine-length alternatives, while the medium profile strikes an ideal balance between weight and heat dissipation for reliable, sustained performance.
Whether you’re building a new AR-15 or upgrading an existing upper receiver, this Diamondback barrel offers precision construction and proven reliability. The .223 Wylde chamber accepts both standard .223 Remington and 5.56 NATO ammunition, providing shooters with expanded ammunition options for training and competition use.
