10.5″ 5.56mm 1:7 Twist Contour 4150 Barrel (Tin Coated)

Description

Engineered for the AR-15 platform, this 10.5 inch barrel provides a compact solution for short-barreled rifle builds without sacrificing internal integrity. Constructed from 4150 Chromoly Steel, the barrel offers the necessary tensile strength and heat tolerance for reliable cycling in the 5.56/.223 caliber.

The interior features M4 Feed Ramps to ensure consistent cartridge seating and extraction, while the Carbine Length Gas System is optimized for proper gas timing with standard upper receivers. The 1:7 Twist rate stabilizes heavier bullet weights, making it versatile for various tactical and competitive loads.

Externally, the barrel is finished with a Tin Coated (Gold Titanium Nitride) surface, providing corrosion resistance and a distinct appearance. The profile terminates in a .750 Diameter muzzle end, compatible with standard muzzle devices, and threads at 1/2 by 28 for secure attachment of compensators or flash hiders.
