Why This Upper Works
The 300 Blackout cartridge excels in short-barreled platforms, and this 10.5" configuration strikes an excellent balance between velocity and maneuverability. The heavy barrel profile helps maintain accuracy while managing recoil, and the M-LOK rail system gives you flexibility to mount optics, lights, and other tactical accessories exactly where you need them.
The 1:8 twist rate is the standard for 300 Blackout, providing reliable stabilization across the full spectrum of subsonic and supersonic loads.
Assembly Note
This is an upper assembly only. You will need a compatible lower receiver to complete your rifle.
