The Faxon AR15 SOCOM Profile Barrel (brand part number 15A58P7NSQ) is a compact, 7.5-inch, 5.56 NATO barrel built for pistol-length AR-15 builds. Faxon cuts this barrel with a pistol-length gas port and a .750-inch gas block seat, then finishes it in Nitride for corrosion and wear resistance. An 11-degree target crown protects accuracy at the muzzle, and the barrel ships unthreaded and without sights, giving builders full control over their choice of muzzle device and sighting system. At 7.5 inches, this barrel is a popular choice for a compact AR pistol build where maneuverability in tight spaces matters more than maximum velocity.

Frequently Asked Questions

Is it legal to buy a 7.5-inch barrel without paperwork? Yes, this barrel by itself is an ordinary Title I part. Federal law restricts installation, not purchase: pairing it with a shouldered, rifle-configured lower that is not registered as a Short-Barreled Rifle would create an illegal, unregistered SBR, so it must go on a pistol-configured lower or a properly registered SBR lower.

What gas system does this barrel use? A pistol-length gas system with a .750-inch gas block seat.

Is this barrel threaded? No, it ships unthreaded, so builders can choose their own muzzle device and threading.
