The Faxon Firearms 9" 1:5 Gunner Profile Blackfaxon AR15 barrel in 338 ARC splits the difference between two time-tested designs to give you a barrel that handles like a dream without sacrificing durability. By blending the solid construction of the Gov't profile with the lighter, snappier handling of the Pencil profile, the Gunner brings your rifle's balance point closer to your body—a real advantage when you're putting rounds downrange all day or hunting from field to stand. This is a purpose-built upper component for shooters and hunters who want accuracy without the weight penalty of a thicker profile.
Faxon manufactures these barrels in-house in Cincinnati, Ohio, and the attention to detail shows. Starting with 416-R Stainless steel—a premium choice for corrosion resistance and precision—each barrel is fully stress relieved and button rifled for consistency. Every one gets air-gauged, magnetically particle inspected, and target crowned at 11 degrees, then individually headspace checked with precision PTG gauges. That's the kind of QC that translates to reliable feeding and tight groups at the range or in the field.
The 9" length with 1:5 twist keeps the 338 ARC cartridge stable and is threaded 5/8x24 for suppressor compatibility if that's part of your setup. Black Nitride finish resists corrosion and looks right at home on a modern AR platform. Note that some shooters report needing upper receiver feed-ramp adjustments—particularly with certain ammunition—and Faxon recommends Duramag magazines for reliable feeding, so do your homework on compatibility before you commit.

Yes, the 9" Gunner profile is built on the M4 extension and fits standard AR15 platforms. However, some customers may need to adjust their upper receiver feed ramps for optimal function, particularly with certain ammunition types. Check compatibility with your specific setup and consult a gunsmith if you encounter feeding issues.
Faxon recommends pairing this barrel with Duramag magazines designed for reliable 338 ARC feeding. This helps ensure consistent performance, especially if you're working with ammunition that's sensitive to feed-ramp geometry.
Yes. The barrel is threaded 5/8x24, a standard suppressor thread pitch. Make sure any suppressor you choose is rated for the 338 ARC and your chosen gas system configuration.
The Gunner profile is built on the same precision manufacturing foundation as Faxon's heavier barrels—stress relieved, button rifled, air-gauged, and target crowned—so accuracy is not compromised. The difference is weight savings and handling: you get a faster-swinging barrel that reduces shooter fatigue without sacrificing the precision QC that goes into every Faxon barrel.
