Overview

Built for a compact .300 Blackout AR-15 setup, this 10.3-inch Performance Series barrel is suited to hunters and shooters who want a shorter pistol-length configuration. It uses Ballistic Advantage’s Hanson profile and includes a pinned low-profile gas block, making it a straightforward option for a streamlined build. The barrel is machined from 4150 Chrome Moly Vanadium steel with a QPQ corrosion resistant finish, and it also features a Nickel Boron coated M4 feed ramp extension. It is not designed to work with aftermarket piston kits, so it is best considered for direct-compatibility builds.

Considerations & Trade-offs

  • The 10.3" pistol-length format is compact, but it does not offer the same barrel length as longer .300 Blackout options.
  • Hanson barrels are not designed to work with aftermarket piston kits, so compatibility is more limited than with some other AR-15 barrel setups.
  • The pinned low-profile gas block is included, which simplifies the setup, but it also reduces flexibility if you prefer to choose your own gas block arrangement.
  • This barrel is specified for a .750 gas block seat, so fitment needs to match that dimension exactly.
