Faxon Firearms
The Faxon AR-15 barrel in 5.56 NATO with a 14.5-inch length and 1:8 twist rate is a no-nonsense mid-length gas system barrel built for shooters who demand accuracy and durability without the hype. Faxon manufactures these barrels in-house, taking them through a rigorous series of inspections and stress-relief processes from raw material to finished product. Whether you're building a carbine for the range, a duty gun, or a reliable workhorse, this Socom-profile barrel delivers the precision foundation your AR needs.
The barrel is made from 4150 CMV steel and button-rifled for consistent performance. It arrives fully nitride-finished inside and out—a process that hardens the steel and resists corrosion without the maintenance burden of stainless. The 11-degree target crown protects the rifling at the muzzle and supports repeatable accuracy shot to shot. Each barrel is individually checked for headspace using precision custom-hardened gauges and undergoes magnetic particle inspection to catch any defects before it ships.
The 1:8 twist rate stabilizes a wide range of 5.56 loads, from lighter training rounds to heavier match and hunting ammunition. The mid-length gas system strikes a balance between reliability and controllability—less recoil impulse than carbine-length, smoother than rifle-length, and proven in countless builds. At 1.5 lbs, it keeps your AR balanced and fast-handling. The .750-inch gas block journal and M4 extension ensure compatibility with standard AR-15 upper receivers and components.
Faxon's commitment to in-house manufacturing means you're not buying a generic barrel with generic QC. Every step—material selection, rifling, heat treat, finishing, and inspection—is controlled by the same shop that stands behind the finished product. Pair this barrel with quality components and a solid upper receiver for a rifle you can depend on.
| Caliber | 5.56 NATO |
| Barrel Length | 14.5 inches |
| Barrel Twist | 1:8 |
| Profile | Socom / Government |
| Material | 4150 CMV steel |
| Rifling | Button rifled |
| Gas System | Mid length |
| Gas Block Diameter | 0.750 inch |
| Gas Block Journal Length | 1.9 inches |
| Muzzle Thread | 1/2-28 |
| Barrel Extension | M4 |
| Inside Finish | Nitride |
| Outside Finish | Nitride |
| Crown | 11-degree target crown |
| Weight | 1.5 lbs |
| QC Process | Air-gauged, stress-relieved, magnetic particle inspected, individually headspace-checked |
Yes. The M4 extension and Socom/Government profile are standard for AR-15 uppers. The 0.750-inch gas block journal and 1.9-inch journal length are compatible with mid-length gas systems and standard AR-15 components.
The 1:8 twist is versatile across the 5.56 NATO spectrum, from lighter training loads through heavier match and hunting rounds. It will handle the vast majority of ammunition you'll encounter.
The barrel arrives finished and inspected. Installation requires the proper tools (barrel wrench, vice, action block, torque wrench) and technical knowledge, or professional gunsmithing. It does not include a gas tube, bolt carrier group, or other upper receiver components.
Nitride hardening creates a durable, corrosion-resistant surface that does not require the same level of maintenance as raw steel and performs well in typical field conditions. Faxon uses 4150 CMV and nitride finishing as a proven combination for reliability and accuracy.
