The by-products of the gas system are vented out the bottom of the gas block, away from the bolt carrier, keeping the action clean and free from contaminants. The end result is significantly improved performance over gas driven rifles.

superior operating endurance. The two-stage piston provides a smooth power delivery stroke to the bolt carrier. The four
position gas regulator can be adjusted for optimum reliability and superior operating endurance. The gas system may be
closed completely for manual operation during training or when using a suppressor.
