Faxon Sport 10.5" 5.56 AR15 Pistol

The Faxon Sport 10.5" 5.56 AR15 Pistol is a purpose-built, compact 5.56 host for shooters who want tight-space handling, a clean parts ecosystem, and a platform that makes sense the moment it comes out of the box. If you’ve ever priced out a short 5.56 build and wondered where the “unknowns” are hiding (gas, cycling, parts fitment, and long-term reliability), this pistol is designed to remove that decision gap with a vetted component stack.

At the core is the Faxon Duty Series SOCOM Profile 10.5" 5.56 NATO barrel (1:8 twist)—paired with a carbine-length gas system for proven short-barrel function and broad ammunition compatibility. This setup is built for practical defensive distances, training volume, and fast handling in a compact footprint.

Built by an American manufacturer. Faxon Firearms is a family-owned manufacturer founded in 2012 and headquartered in Greater Cincinnati, Ohio. The Faxon family’s manufacturing and engineering roots date back to 1978—producing mission-critical components for aerospace, defense, and industrial programs. That same process control and machining discipline carries directly into our firearms, barrels, receivers, and critical small parts.

Key Features

  • 10.5" 5.56 NATO Duty Series SOCOM Profile barrel (1:8 twist)
  • Carbine-length gas system for short-barrel 5.56 function and tuning flexibility
  • Enhanced forged upper receiver (Faxon) for a durable, duty-minded foundation
  • Forged lower receiver with tensioning screw to help tighten receiver fit
  • Faxon Streamline 9" M-LOK handguard with top rail for accessories and lights
  • Faxon Superfinished 5.56 M16 BCG – Nitride for smooth cycling and easier cleaning
  • Faxon fixed .750" low-profile gas block + carbine-length stainless gas tube
  • Faxon 5.56 A2 Flash Hider (1/2"-28)
  • Includes Magpul Gen M2 30-round magazine

Use Cases

  • Home & property defense: compact handling with 5.56 NATO’s established performance at practical distances
  • Training & range work: reliable configuration built around proven components
  • Suppressed readiness: viable suppressor host with the right mount and tuning (backpressure varies by suppressor)
  • Truck / pack / tight-space carry: short overall length with a serviceable, upgrade-friendly ecosystem

Who it’s for: shooters who want a compact 5.56 pistol built around known-quality parts and a clear upgrade path (optics, lights, mounts, suppressor ecosystem).
Who it’s not for: buyers prioritizing maximum velocity—this is a short-barrel, fast-handling 5.56 platform by design.
