Overview
Built for AR-15 owners setting up a compact .300 Blackout upper, this 10.3-inch Performance Series barrel is aimed at pistol-length configurations where a shorter format is preferred. It uses Ballistic Advantage’s Hanson profile and includes a pinned low-profile gas block, giving it a purpose-built setup for compatible builds. The barrel is machined from 4150 Chrome Moly Vanadium steel with a QPQ corrosion resistant finish, and it features a Nickel Boron coated M4 feed ramp extension. It is HP and MPI tested, and it is not designed to work with aftermarket piston kits.

Considerations & Trade-offs
- Hanson barrels are not designed to work with aftermarket piston kits, so this is a poor fit if your build uses that type of system.
- The 10.3 inch pistol gas setup is specific to compact .300 Blackout builds and is not intended for longer rifle-gas configurations.
- The pinned low-profile gas block is included, which simplifies setup but leaves less flexibility for builders who want to choose their own gas block arrangement.
- The 1/7" 5R twist rate is fixed, so it may not match every load preference or use case in .300 Blackout builds.
