The gearbox is made on the base of neatly chosen parts, allowing to gain great muzzle velocities. The application of the 8mm slide bearings significantly improve the operation of the thread-wheels. The bearings and the thread-wheels are chosen to withstand all the forces accompanying the operation with powerful springs.
The chromed cylinder significantly improves the O-ring type seal's lifespan which is located in the piston's head. The reinforced piston itself is equipped with a steel plate allowing certain operation with strong springs. The metal main spring guide is necessary in this case - this is why one is used.
The electric unit itself consists of low-resistance wiring which decrease the batteries load.
