12.5″ .308 Cal 1:10 Twist 4150 Barrel (Stainless)

Description

This 12.5″ barrel is machined from 4150 Chromoly Steel with a Stainless Steel finish, designed for integration into a .308 caliber upper receiver. The barrel features a 1:10 Twist rate, which stabilizes heavier projectiles commonly used in .308 applications. It is equipped with a .750 Diameter gas block taper to accommodate standard carbine-length gas systems, ensuring reliable cycling when paired with appropriate gas tubes and blocks.

Constructed from 4150 Chromoly Steel, this barrel offers a balance of durability and weight management. The Stainless Steel finish provides corrosion resistance and a brushed metallic appearance. The muzzle end is threaded to 5/8 x 24 Thread specifications, allowing for the attachment of compatible muzzle devices such as compensators or flash hiders. The Carbine Gas System designation indicates the gas port location is optimized for shorter gas tube lengths, which is critical for maintaining proper timing in compact builds.

Key specifications include a total weight of 31 oz, which contributes to the overall balance of the upper receiver. The solid pattern construction ensures a uniform profile from the gas block to the muzzle, providing consistent gas flow and structural integrity. This barrel is intended for builders who require precise .308 caliber performance with established dimensional standards. The 12.5″ length offers a compact footprint while retaining sufficient velocity for the caliber. All dimensions and material designations are exact to the supplied data, ensuring compatibility with standard AR-15 platform components.
