Faxon Duty 556 14.5" Carbine Barrel

Faxon Duty 556 Carbine Barrel

The Faxon Duty 556 represents a straightforward approach to AR-15 barrel design—quality materials, proven geometry, and honest engineering without unnecessary complications.

Key Features

• Caliber & Twist: 5.56 NATO with 1:8 twist rate for reliable performance across a wide range of ammunition weights
• Length: 14.5" carbine length, ideal for compact builds and tactical applications
• Material: 4150 chrome-moly vanadium steel for superior strength and heat resistance
• Finish: Black chrome magnetic phosphate coating provides corrosion resistance and durability
• Profile: Medium taper design balances weight and rigidity
• Compatibility: Direct drop-in replacement for standard AR-15 platforms

Performance Characteristics

The 1:8 twist rate stabilizes modern 5.56 ammunition effectively, from lighter 55-grain loads to heavier 77-grain rounds. The 14.5" length maintains velocity while keeping overall rifle length manageable for close-quarters work or vehicle operations.

Faxon's manufacturing process emphasizes consistency and reliability. The black chrome finish resists corrosion better than standard parkerizing, making this barrel suitable for duty use, training, or recreational shooting.

Practical Application

Whether you're building a duty rifle, a home defense carbine, or a training platform, this barrel delivers the performance you need without premium pricing. It's the kind of component that lets you focus on marksmanship rather than equipment concerns.
