- Carbon and gases are expelled outward at the gas block, not towards the action.
- Corrosive resistant coating processes.
- Harmonics are not transferred into the barrel.

- For 300BLK we only recommend a Pistol Gas Length and a Low Mass Carrier for optimal performance.
We recommend using a our Adams Arms barrel nut, standard G.I. barrel nut, or barrel nut with similar measurements for proper fit and function of the kit. Many aftermarket proprietary barrel nuts do not offer the clearance for the drive rod or proper seating of the spring and bushing.
