Faxon Ar15 Barrel 5.56 Nato - 14.5" 1:8 Socom Profile Black$166.19
Availability: In Stock
The Faxon AR15 barrel in 5.56 NATO with 7.5" length and 1:8 twist is purpose-built for shooters who need precision in a short, handy package. Faxon manufactures these barrels in-house using certified 4150 CMV steel, subjecting each one to rigorous stress relief, air-gauge testing, and magnetic particle inspection. The result is a rifle barrel that combines quality materials with exacting tolerances—ideal for builders who refuse to compromise on accuracy whether you're running a pistol-caliber upper, a short-barreled AR for specialized applications, or an SBR build that demands reliability.
The Socom/Government profile keeps weight down while maintaining the rigidity needed for consistent shot placement. Faxon's 11-degree target crown is finished to spec, and every barrel is individually headspace-checked using precision custom-hardened gauges—a standard many manufacturers skip. The nitride finish inside and out provides corrosion resistance and durability without the brittleness some coatings introduce. With a mid-length gas system and standard M4 extension, this barrel integrates seamlessly into your existing upper receiver.
At 1.50 lbs, the 7.5" profile won't bog down your build, and the 1/2-28 muzzle thread accepts common suppressors and muzzle devices. The .750" gas block diameter and 1.9" journal length are spec-appropriate for the bore size and gas system length. Whether you're assembling a short-range dedicated upper or a specialized platform, Faxon's attention to process control and testing separates this barrel from commodity options.

This barrel uses a standard M4 extension and mid-length gas system, making it compatible with any standard AR15 upper receiver. You'll pair it with a standard bolt carrier group. The .750" gas block diameter and 1.9" journal length are spec-correct for mid-length systems.
Yes. The barrel is threaded 1/2-28, which is the standard AR15 muzzle thread and accepts the vast majority of suppressors, muzzle brakes, and flash hiders on the market.
While the 7.5" length limits velocity and effective range compared to longer barrels, Faxon's quality control—stress relief, magnetic particle inspection, individual headspace checking, and 11-degree target crown—ensures this barrel delivers accuracy within its intended use. It's better suited to close-quarters or specialized applications than distance shooting.
Faxon manufactures in-house using certified 4150 CMV steel and stress-relieves every barrel. Each one is individually headspace-checked, air-gauge tested, and magnetic particle inspected throughout production. Many budget barrels skip these steps. The nitride finish is applied and tested for consistency. It's the process control and individual inspection that separates them.
