Overview
The Faxon Gunner 9" barrel is chambered in .338 ARC with a maker-listed 1:5 twist, pistol-length gas system, and 5/8x24 muzzle threads. It is the short Faxon option in the guide. The current SAAMI drawing lists an optional 1:8 twist; the faster 1:5 rate is Faxon's choice for this compact barrel.
Faxon's product page documents the barrel dimensions and chamber. A custom build still needs the maker-matched bolt and verified headspace. Magazine fit is independent of the bolt choice and must come from the upper and lower documentation.
The barrel uses 416R stainless steel, a nitride finish, 5R rifling, and Faxon's Gunner profile. Because it is under 16 inches, the completed firearm needs a legally compliant configuration. Any suppressor must have maker-approved .338-inch bore clearance and satisfy the model's barrel, mount, and firing-schedule limits.
Key Features
- 9" length keeps a suppressed .338 ARC subsonic build short and balanced
- 1:5 twist is the maker-listed rate for this exact short barrel
- 416R stainless steel construction with nitride finish
- 5R rifling and Gunner pencil/government hybrid profile
- Pistol-length gas system documented by Faxon for this barrel
- 5/8x24 muzzle threads for compatible devices and maker-approved suppressor mounts
Pros
- +9" length is purpose-built for a compact suppressed subsonic host
- +1:5 twist is documented directly by Faxon
- +Gunner profile keeps a short barrel light and maneuverable
- +Nitride finish resists corrosion under heavy suppressed firing
- +5/8x24 threads accept compatible devices and maker-approved suppressor mounts
Cons
- −Under 16", so the firearm needs a legally compliant short-barrel configuration
- −1:5 is a Faxon product choice, not the optional 1:8 twist on the SAAMI drawing
- −Short barrel sacrifices supersonic velocity versus longer lengths
- −Requires the barrel-maker-matched bolt and verified headspace, not a standard 5.56 bolt
