16″ 5.56mm 1:7 Twist M4 4150 Barrel Carbine Length Gas

Description

This 16-inch barrel is constructed from 4150 Chromoly Steel, a material chosen for its durability and resistance to heat and wear during repeated firing cycles. It features 1:7 Twist rate, which stabilizes heavier bullet weights often used in 5.56/.223 caliber applications. The barrel is chambered in 5.56×45, ensuring compatibility with standard ammunition for this platform. The M4 Contour profile provides a balanced weight distribution, reducing the overall mass of the upper receiver while maintaining structural integrity. It utilizes Carbine Length Gas system with a .750 gas platform system to ensure proper gas flow and reliable cycling. The muzzle end features a 1/2 by 28 Thread, allowing for the attachment of standard muzzle devices. M4 Feed Ramps are integrated into the chamber to facilitate smooth magazine insertion and feeding. The exterior is treated with a Black Nitride Coating for enhanced corrosion resistance and a durable finish. This component is essential for builders constructing a standard-specification AR-15 upper receiver.
