Nightstalker piston for perfect AOE setup

Smoothest & Strongest Gear Pairing

The best drop-in solution for the most perfect AOE in the market. Stress free pickup tooth as the most optimum angle followed through by the flawless meshing with the sector gear.

The Nightstalker Piston paves a new standard for gearbox performance.

Minimum 2-3 Stress Distribution Points of Contact

The gears on the piston rack has been drastically designed to improve upon the efficiency of the meshing with the Sector gear. On a stock set-up it uses a 1 to 1 gear meshing taking on the strain which means the gears are highly susceptible to breaking at the weakest point.

With the Nightstalker Piston rack is designed to mesh with 3 point of contact at a given time, distributing the strain on those gears rather than just 1. This will reduce the wear, run efficiently and reduce gearbox whine.

Efficient Pick-up Tooth

Once the Nightstalker Piston is installed, the sector gear will be perfectly positioned to begin pulling the piston in the most energy efficient and reduced force that will be applied onto the first pick-up tooth. As a result you can expect a much snappier trigger response!

On the other hand through a stock setup, it takes a good considerable amount of energy to start pulling the piston at the steeper, disadvantaged angle causing more strain on the gear meshing, stress on the motor, and causing too much heat in the system.

Offset Piston Rack Segment

The rack is offset by 0.5mm to allow the user to utilize additional shimming space with the sector gear to maximize the meshing surface of both gears.

Grease Retaining Rails

The Rails are designed to hold more grease inside to consistently perform smoothly on each cycle by keeping resistance to a minimum.

There will be less needs requirements for gun maintenance after install.

Throw the Piston at any Build

Whether you are looking to replace your piston for maintenance or to build something stronger, the piston can withstand anything you throw at it. Its virtually indestructible.

Fully tested for DSG and TSG builds!

Reduced Railing Resistance for Stable FPS

The railing width on the piston is slightly shorter than other pistons in the market. This is drastically reduce the need for the rails to slide against the walls of the gearbox shell.

As a result, allows the piston to slide back and forth with minimum resistance, which can help to achieve a stable FPS output.

Compatible with All Piston Heads Brands

The Nightstalker Piston can be used with all third party or stock AEG piston heads. The hole which connects the piston with piston head uses interference fitting to be as snug as possible and later locked using our heat treated locking screw which is included.
