Product Description

The Faxon Firearms Match Series Heavy Fluted 18" .308 Winchester AR10 Barrel is engineered for shooters who demand precision, durability, and consistent performance in a balanced package. Manufactured in-house from gun-barrel-quality 416-R stainless steel bar stock, this barrel features 5R button rifling - a hybrid rifling design with lands opposite grooves and reduced sharp angles that minimizes jacket deformation, boosts velocity, and simplifies cleaning. The heavy fluted profile reduces overall weight while increasing surface area for superior heat management, making it equally at home on the competition line or in the field. After rigorous testing, each barrel receives salt bath nitride (QPQ) treatment inside and out, dramatically improving corrosion resistance, wear life, and overall service longevity. The DPMS/LR-308 compatible extension is finished with a Nickel Teflon coating for outstanding dry lubricity, corrosion resistance, and a tighter fit between the extension and receiver for enhanced accuracy. Completed with a recessed 11-degree target crown and magnetic particle inspection (MPI), this American-made barrel is built to perform when it matters most.

Product Highlights

  • 5R Button Rifling: Hybrid rifling geometry reduces jacket deformation, supports consistent velocities, and makes bore cleaning easier after extended shooting sessions.
  • Salt Bath Nitride (QPQ) Inside and Out: Full QPQ nitride treatment improves corrosion resistance, wear resistance, and service life across all conditions.
  • Heavy Fluted Profile: Deep flutes increase surface area for effective heat dissipation and trim carry weight while maintaining the rigidity needed for repeatable precision.
  • Nickel Teflon Coated DPMS/LR-308 Extension: Provides exceptional dry lubricity, corrosion protection, and a tightened receiver interface for improved accuracy potential.
  • Rifle-Length Gas System with Recessed 11-Degree Target Crown: Delivers a smooth recoil impulse, broad tuning flexibility, and a protected muzzle crown for consistent shot-to-shot performance.
