The Redline Gen2 is one of the most practical enhancements for your Airsoft M4. This cylinder replacement device is a marked improvement over its predecessor. It features a closed HPA engine and offers a reliable upgrade to your firing mechanism.

The Gen 2 comes with a solenoid and a convenient forward-biased nozzle like the original piece. As previously mentioned, the product fires from a closed bolt.

The biggest difference between the original and this piece is the lack of external nozzle airline. The internals has also been updated, and the chamber size was reduced to fit your weapon more easily. However, the manufacturer retained the same functionality. This means the setup and performance that won the N7 engine such praise is identical.

Due to the air-balanced return and closed-bolt design, the conversion kit consistently positions the rounds in your bucking. This makes it superior to open-bolt engines, as shot consistency is higher. Other benefits of this innovation include greater precision at long ranges and tighter groupings.

The manufacturer didn’t take a chance regarding the dump chamber design. The component is mechanically sealed and doesn’t rely on the dwell to control airflow. Instead, there’s an internal chamber where the supply regulator sets the pressure.

Once fired, the internal chamber detaches from your supply, releasing the content in the barrel to drive your BBs. This feature improves shot consistency even further since no air is wasted.
Setting up the conversion kit is pretty straightforward. You need only set the output pressure of the supply regulator to match your Joule requirements, and that’s all there is to it.
