The Faxon Match Series 18" Heavy Fluted .223 Wylde pairs match-grade materials and manufacturing with a heavy-fluted contour that improves thermal management and stiffness while trimming weight vs. a straight heavy barrel. Designed for shooters who demand repeatable accuracy over long strings of fire, this barrel is purpose-built for competition, precision training, and duty applications.

Manufactured from premium 416R stainless and button-rifled with 5R lands, then treated with salt bath nitride inside & out, each barrel is stress-relieved, air-gauge tested, MPI-inspected, and headspace-verified in-house. The M4 extension is finished with Nickel Teflon to increase lubricity and tighten the extension-to-receiver interface for consistent shot-to-shot performance.

Key Benefits

• Heavy Fluted profile: Increased rigidity and cooling surface area with weight savings compared to full-contour heavy barrels.
• .223 Wylde chamber: Optimized for match accuracy with .223 Rem while safely accepting 5.56 NATO pressures.
• Match-grade construction: 416R stainless, 5R rifling, 1:8 twist for excellent accuracy across bullet weights.
• Salt Bath Nitride I/O: Enhanced corrosion resistance, reduced fouling, and extended barrel life.
• Nickel Teflon M4 extension: Improves feeding and repeatable receiver fit.
• Full QC: Stress relieved, air-gauge tested, MPI, and headspace checked at every barrel.

Overview: 18" Match Series Heavy Fluted .223 Wylde Barrel

The Faxon Match Series 18" Heavy Fluted .223 Wylde is engineered for shooters who demand stability, heat management, and match-grade accuracy in a rifle-length platform. Built from 416R stainless bar stock and button-rifled with 5R geometry (1:8 twist), this barrel minimizes jacket deformation and fouling while maximizing uniformity shot-to-shot. The heavy fluted contour increases the barrel's surface area for better cooling and adds rigidity where it counts — delivering consistent groups through sustained strings of fire without the full weight penalty of a straight heavy barrel.

Faxon Match barrels receive a salt bath nitride treatment inside and out to lock in the bore, enhance corrosion resistance, and reduce the frequency and severity of fouling. Each barrel is fully stress-relieved, air-gauge tested, magnetic particle inspected (MPI), and individually headspace-verified to meet demanding quality standards. The M4 extension is finished with a Nickel Teflon coating to improve dry lubricity and tighten the extension-to-receiver fit — a small detail that improves feeding and mechanical consistency.

The rifle-length gas system smooths the recoil impulse for faster follow-ups and more controllable strings, making the 18" Heavy Fluted an excellent choice for precision matches, extended training, and duty use where sustained accuracy and temperature management matter. If you want a match-grade barrel that stays cool, shoots straight, and lasts, the Faxon Match Series 18" Heavy Fluted .223 Wylde delivers.
