Quick spring change system

The QSC system (the quick spring change system), means that the spring guide can be removed from the gearbox without removing the gearbox from the body. There are locks on the head of the spring guide and the holes in the gearbox. By turning the spring guide, the spring guide and spring can be removed. This weapon has also a QSC system on the body - no need to remove the gearbox from the body - just remove the stock and unscrew the stock tube.

Cylinder and piston

The cylinder is polished for smooth piston action and increased performance.
The piston has a metal tooth for maximum durability with stronger springs. The piston head is plastic with rubber compound, for a softer and lighter stop and longer life.

Gears

Metal gears have a straight tooth that reduces axial forces. The piston gear is equiped with a BB supply cam for smooth BBs supply from magazine, even on high rate of fire.
