Faxon Firearms FX22A216X 22 ARC 16" Barrel 15" M-LOK Handguard

The Faxon Firearms FX22A216X delivers precision-engineered components for the emerging 22 ARC cartridge platform. This complete upper assembly combines a 16-inch barrel with an integrated 15-inch M-LOK handguard system, offering shooters enhanced accuracy potential and modularity in a compact package.

What Makes This Different

The 22 ARC cartridge fills the performance gap between traditional .223 Remington and larger calibers, delivering superior ballistics with manageable recoil. Faxon's barrel profile optimizes this cartridge's capabilities through precise chamber dimensions and rifling specifications. The integrated handguard design eliminates the barrel nut interface found on traditional systems, reducing potential accuracy-robbing stress points while maintaining rock-solid lockup.

Key Features

• 16-inch button-rifled barrel chambered in 22 ARC with 1:7 twist rate
• 15-inch M-LOK compatible handguard with full-length top rail
• Integrated barrel extension and handguard design for enhanced rigidity
• QPQ nitride finish provides corrosion resistance and extended barrel life
• Compatible with standard AR-15 lower receivers and BCG assemblies
• Multiple M-LOK attachment points at 3, 6, and 9 o'clock positions
• Low-profile gas block with .750-inch diameter journal

Field performance testing demonstrates the 22 ARC's ability to maintain supersonic velocities beyond 400 yards while delivering flatter trajectories than comparable .223 loads. The barrel's medium contour balances heat dissipation with weight considerations, making it suitable for precision shooting applications and hunting scenarios where shot placement matters most. The M-LOK handguard accommodates bipods, lights, and other accessories without compromising the system's inherent accuracy.
