Faxon Firearms FX22A320 22 ARC 20" Flame Fluted Barrel Upper

The Faxon Firearms FX22A320 delivers precision shooting performance with its flame-fluted 20-inch barrel chambered in 22 ARC. This complete upper receiver assembly combines match-grade accuracy with lightweight construction for competitive shooting and hunting applications.

What Makes This Different

The flame fluting pattern reduces barrel weight by approximately 15% while maintaining structural integrity and heat dissipation properties. Black nitride coating provides superior corrosion resistance compared to standard phosphate finishes, extending barrel life beyond 5,000 rounds. The 20-inch barrel length maximizes velocity potential of the 22 ARC cartridge, delivering flat trajectory performance at extended ranges.

Key Features

• 20-inch flame-fluted barrel with black nitride finish for enhanced durability
• 22 ARC chamber optimized for high ballistic coefficient projectiles
• 15-inch M-LOK handguard with full-length top rail for optics mounting
• Magpul MOE grip provides consistent hand positioning and control
• Standard AR-15 platform compatibility with mil-spec components
• Button-rifled barrel with 1:7 twist rate for bullet weights 75-90 grains
• Low-profile gas block with carbine-length gas system

Field testing demonstrates consistent sub-MOA accuracy with match ammunition at 100 yards. The 22 ARC cartridge bridges the gap between 5.56 NATO and larger calibers, offering superior ballistic performance for varmint hunting and precision shooting. Weather-sealed construction handles moisture and temperature variations without accuracy degradation.
