Complete QD gearbox V2 for M4/16 - rear wiring
Complete QD gearbox for M4/M16 series airsoft AEG guns.
This is the original gearbox used by Lancer Tactical in their weapons.
Inside the gearbox you will find the classic assembly. As an extra you can consider a piston with full-metal teeth, 8 mm bearings, a sector gear delayer clip or a quick spring change system. Using an inbus wrench or a screwdriver, you can easily slide the spring guide and spring out of the gearbox. Replacing the spring is a matter of minutes. The spring inside is approximately M90 in force. The wiring is routed into the stock.

Quick spring change system
The gearbox has QSC system - spring change takes few minutes. 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.
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.
