TacFire AR Barrel 308 Win 18" 1:10 Twist Black Nitride for AR-10

The TacFire AR Barrel is a replacement 18" barrel chambered in 308 Win, built for AR-10 platform rifles. Whether you're completing a custom AR-10 build or refreshing a worn factory barrel, this drop-in profile provides the accuracy and reliable performance expected from a quality .308 Winchester chambering.

The barrel is treated with a Black Nitride finish, a surface treatment that increases surface hardness, reduces friction, and adds wear and corrosion resistance while maintaining the classic slim AR-10 contour. A 1:10" twist rate stabilizes a wide spread of 308 Win bullet weights, from lighter projectiles up through heavier match and hunting loads, making this a versatile choice for mid-range applications.

Designed as a direct replacement barrel for the AR-10 platform, this 18-inch 308 Win barrel pairs with your existing upper receiver, gas system, and handguard to complete the build. Sold as a single barrel only.
