Diamondback 8.5" pistol-length barrel in 300 Blackout. Constructed from 4150 chrome moly vanadium steel with black nitride finish and 1:8 twist rate.
This 8.5" barrel from Diamondback is purpose-built for 300 Blackout pistol builds and short-barreled rifles. Whether you're replacing a worn barrel or completing a custom build, this barrel delivers the performance you need.
The 4150 CMV steel provides excellent durability and reliability, while the black nitride finish offers superior corrosion resistance and a professional appearance. The 1:8 twist rate stabilizes a wide range of 300 Blackout projectiles, from lighter 110-grain rounds to heavier subsonic loads.
The pistol-length gas system is ideal for shorter platforms and provides reliable cycling with both supersonic and subsonic ammunition. This makes it an excellent choice for suppressed or unsuppressed applications.
