If you’re building or upgrading a 6mm ARC AR-15 for precision, hunting, or long-range steel, this Faxon Match Series Target barrel is a top-tier foundation.
Purpose-Built 6mm ARC AR-15 Barrel
The 6mm ARC (Advanced Rifle Cartridge) is designed for impressive ballistic performance from the AR-15 platform. Faxon’s 20" Match Series Target barrel is tuned to get the most out of it:
Chambered in 6mm ARC – Designed around high-BC 6mm bullets for long-range work.
20" length – A sweet spot for maximizing velocity while keeping the rifle manageable and well-balanced.
AR-15 compatible – Standard AR-15 receiver and handguard platform, with a 6mm ARC bolt and magazine setup.
This barrel is ideal for shooters looking to stretch the AR-15 to mid and long ranges with a highly efficient cartridge.
416-R Stainless Steel – Precision and Consistency
The barrel is machined from 416-R stainless steel, the go-to choice for many precision barrel makers:
Excellent machinability for precise rifling and chamber geometry.
Good corrosion resistance, especially important for rifles used in mixed weather conditions.
Well-known for delivering strong accuracy potential in precision rifles.
Paired with Faxon’s tight tolerances and quality control, 416-R provides a consistent platform shot after shot.
Bead Blast Finish – Classic, Low-Glare Stainless Look
This Match Series barrel features a bead-blasted stainless finish:
Soft, matte sheen that cuts down on reflection and glare.
Clean, professional appearance that pairs perfectly with stainless or contrasting receivers and handguards.
Shows machining quality while maintaining a practical, non-flashy profile.
It’s an excellent aesthetic choice for precision, hunting, and competition builds.
1:7.5" Twist & 5R Rifling – Optimized for Heavy 6mm Bullets
To take full advantage of 6mm ARC’s potential with long, high-BC bullets, this barrel uses:
1:7.5" twist rate – Ideal for stabilizing modern heavier 6mm projectiles commonly used in 6mm ARC loads (like 103–108 grain class).
5R rifling – A premium rifling style with 5 lands and grooves and sloped sides that:
Reduces bullet deformation.
Minimizes fouling buildup.
Promotes more consistent gas sealing and accuracy over traditional rifling profiles.
For long-range precision and repeatable groups, the twist and rifling combo is a major advantage.
Match Series Target Profile – Built for Accuracy
Faxon’s Match Series Target barrels are designed with accuracy at the forefront:
Heavier, stability-focused profile that resists barrel whip and heat-induced point-of-impact shifts.
Ideal for bench, prone, competition, and precision field use where consistency matters more than ultra-light weight.
Balanced well with a 20" length to keep the rifle from being overly front-heavy while still maintaining rigidity.
It’s a fantastic choice for shooters who prioritize precision above all else in their AR-15 build.
Mid-Length Gas System – Smooth, Reliable Operation
This barrel uses a mid-length gas system, which is a proven sweet spot for 18–20" AR barrels:
Smoother recoil impulse than carbine-length gas systems.
Often easier on internal components, with less violent cycling and reduced wear.
Aids in maintaining sight picture and faster follow-up shots.
Coupled with a tuned buffer system and quality BCG, this mid-length setup helps your 6mm ARC run smoothly and consistently.
5/8x24 Threaded Muzzle – Ready for Brakes and Suppressors
At the muzzle, the barrel is cut with 5/8x24 threads, the standard for many precision and AR-15 barrels in 6mm/.30-cal families:
Compatible with a wide array of muzzle brakes, compensators, and suppressor mounts.
Makes it easy to add a recoil-reducing brake for competition, or a suppressor (where legal) for hunting and steel.
Gives you flexibility to tune recoil, blast, and overall handling characteristics to your preference.
A properly installed muzzle device can further enhance control and long-range performance.
Match-Grade Accuracy for Competition, Hunting, and Steel
This Faxon Match Series Target 6mm ARC 20" barrel is an excellent fit for:
PRS-style gas gun matches & practical precision – Take advantage of 6mm ARC’s flat trajectory and low recoil.
Long-range steel – Engage targets from 400 to 1,000+ yards with high-BC bullets and reliable barrel performance.
Hunting – Ideal for coyotes, hogs, and medium game where precise, ethical hits at extended ranges are key.
Serious training and practice rifles – Perfect when you want match-grade accuracy in a semi-auto format.
If you want a “do-it-all” precision AR in 6mm ARC, this barrel is built exactly for that role.
Easy Upgrade for Accuracy-Focused AR-15 Builds
Swapping to a Faxon Match Series barrel can dramatically elevate your rifle’s performance:
Better inherent accuracy potential compared to many mass-produced barrels.
Refined rifling and chamber to support consistent velocity and tight ES/SD in quality handloads or match ammo.
High-end features (5R rifling, stainless, bead blast, tuned twist) in a package built for real use—not just spec sheet appeal.
For builders, it’s the perfect core component around which to design a serious 6mm ARC precision rig.
