The Faxon AR-15 barrel in 5.56 NATO with a 14.5" Gunner profile is built for shooters who want a lightweight, accurate barrel without sacrificing heat management or shot-to-shot consistency. Faxon's proprietary Gunner profile uses a government-profile diameter from the extension back to the gas block, then transitions to a pencil profile forward—a design that strips unnecessary weight from the front end while keeping material where it matters most: behind the gas block where heat builds up fastest. That geometry keeps your barrel cooler longer and minimizes harmonic whip, making it equally at home on a carbine for duty use, a precision AR for distance work, or a versatile 3-gun rifle.
Made entirely in-house by Faxon, each barrel begins with 4150 CMV steel and is button-rifled with a 1:8 twist—a rate that stabilizes everything from lightweight varmint rounds to heavier match ammunition. The twist is fast enough for modern projectile weights without being so aggressive that you're forced into a narrow ammo diet. Every barrel is stress-relieved to eliminate residual tension, air-gauged for dimensional consistency, and dressed with an 11-degree target crown for clean, precise bullet release. Before it ships, Faxon subjects each barrel to a production gauntlet: headspace verification with hardened precision gauges, multiple QC checks throughout manufacturing, and a Nitride finish that hardens the steel surface for corrosion resistance and longer service life.
This is a no-nonsense, middle-of-the-road barrel length that balances velocity, handling, and compliance across most states—suitable for hunting, target shooting, or general duty use. The Gunner profile has earned respect in the AR community precisely because it solves a real problem: how to build a barrel that shoots reliably without carrying excess weight or running hot. If you're building an AR that needs to work hard and shoot straight, this is exactly the kind of engineering detail that separates a rifle you trust from one you merely own.
| Caliber | 5.56 NATO |
| Barrel Length | 14.5" |
| Twist Rate | 1:8 |
| Profile | Gunner (Government to gas block, pencil forward) |
| Material | 4150 CMV Steel |
| Rifling Type | Button Rifled |
| Crown | 11-degree target crown |
| Finish | Nitride |
This Faxon barrel has a 1:8 twist rate. A 1:8 twist is fast enough to stabilize a broad range of 5.56 NATO loads, including modern heavier projectiles, without being overly aggressive. You won't be locked into a narrow ammo diet.
The Gunner profile uses government-standard dimensions from the extension to the gas block, then tapers to a pencil profile moving forward toward the muzzle. This design removes weight from the front of the barrel—improving handling and reducing fatigue—while concentrating material toward the rear where heat accumulation is greatest. The result is a barrel that stays cooler longer and shoots with less harmonic whip than heavier profiles.
Yes. The 14.5" length is a common choice for carbine-length gas systems and works well for hunting, range shooting, and tactical applications. You'll need to verify compatibility with your upper receiver and gas system, but the barrel itself is a standard AR-15 profile.
Every Faxon barrel is manufactured 100% in-house, stress-relieved, air-gauged for dimensional accuracy, and finished in Nitride. Before shipping, each barrel undergoes individual headspace verification with precision hardened gauges and passes multiple QC inspections throughout the production process.
