TacFire AR-10 .308 Win 20" Black Nitride Barrel

A TacFire AR-10 .308 Win 20" Black Nitride Barrel is a direct replacement barrel built for the AR-10 platform, chambered in .308 Winchester. Whether you're refreshing a worn shooter, experimenting with a different barrel length, or building a dedicated precision or hunting upper, this is a straightforward, no-frills upgrade that gets the job done. The black nitride finish provides a durable, low-maintenance protective coating—standard practice for modern rifle barrels—and the 20-inch length balances velocity, handling, and sight radius in a traditional configuration familiar to AR shooters.

TacFire barrels are known for offering solid performance at a practical price point, making them popular with shooters who prioritize function over boutique branding. A 20" .308 barrel is equally at home on a range gun, a hunting rig, or a modular defensive build. The nitride surface resists corrosion and wear, so you can spend less time worrying about maintenance and more time shooting. Drop-in installation requires standard AR-10 tools and armorer knowledge—this is a barrel only, so you'll need the upper receiver, handguard, and gas system to complete your build.

If you're running an AR-10 and want a proven, cost-effective barrel swap without paying premium dollars for a household name, this TacFire option delivers the specs you need in a format that works. Nitride barrels have a proven track record in the field, and 20 inches is a proven length for .308 ballistics and ergonomics.
