The Faxon 5.56 NATO 10.5″ SOCOM Barrel is built for shooters seeking proven performance in a compact, duty-grade configuration. Machined in-house from 4150 Chrome Moly Vanadium (CMV) steel and treated with a QPQ Nitride finish, this barrel offers exceptional corrosion resistance and enhanced surface hardness, ideal for rugged use and high round counts. The M4 feed ramp extension is coated in Nickel Teflon, ensuring reliable cycling across a wide range of ammunition types.

Like all Faxon barrels, the 10.5″ SOCOM model is 100% manufactured in the U.S.A. from gun-barrel-quality bar-stock. Every barrel is thoroughly tested and individually inspected for headspace using precision custom hardened gauges to guarantee flawless fit and performance. This model features a Carbine-length gas system and a 0.75″ gas block journal, offering reliable gas flow and compatibility with a broad range of upper configurations.

The SOCOM profile is a heavy, rigid contour originally developed for military use. Its added mass offers excellent heat distribution and durability, especially under sustained fire or suppressed applications. This profile has become a staple for tactical rifles and SBRs thanks to its outstanding balance of heat control, accuracy, and strength.

Whether you’re building a compact defensive rifle, range tool, or professional-use SBR, the Faxon 5.56 NATO 10.5″ SOCOM Barrel delivers the strength, precision, and reliability required for the most demanding shooting environments.
