16″ 5.56mm 1:7 Twist 4150 Barrel Mid Length Gas

Description

This 16 inch Barrel Mid chambered for 5.56mm ammunition, designed for standard AR-15 platform builds. It is constructed from 4150 Chromoly Steel, a material chosen for its durability and resistance to wear during high-volume firing. The 1:7 Twist rate is specified to stabilize heavier bullet weights, providing versatility for various loads within the 5.56/.223 caliber family. The exterior is treated with a Black Nitride coating, which enhances corrosion resistance and provides a durable matte black finish visible in the product imagery.

Gas operation is facilitated by a .750 Gas Platform System integrated with a Mid Length Gas System. This configuration positions the gas block further forward than a carbine-length setup, a choice often made by builders seeking specific cycling characteristics. The barrel features M4 Feed Ramps to ensure proper alignment with the upper receiver’s feed lips. The muzzle end is threaded to a 1/2 by 28 Thread standard, allowing for the attachment of compatible muzzle devices. Faint white Markings Spiral Engraved Near Break are present for identification purposes.

The solid pattern design offers a clean profile along the gas tube, suitable for builders who prefer a minimalist aesthetic before installing handguard components. This barrel serves as a core component for experienced AR-15 builders, requiring integration with a compatible upper receiver, bolt carrier group, and appropriate gas tube. The combination of 4150 steel construction, 1:7 twist rate, and mid-length gas system provides a functional foundation for reliable operation in standard configurations.
