The Modify Quantum Double Cycle Gear Set is an extremely advanced set up and should only be attempted by an expert technician. The Quantum Double Cycle gear set features a set of teeth of either side of the sector gear which allows two shots per gear cycle, essentially doubling your rate of fire. The Quantum Double Cycle Gear set uses a half-cycle cut-off system which is able to retain semi-automatic fire which is usually very tricky to pull off with a short stroke style system. The sector clip on this gear system is shaped in such a way to delay the release of the tappet plate to avoid any feeding malfunctions. Modify recommends that this setup should only be used with a 363mm inner barrel or shorter due to the reduced air compression that the short stroke system produces.
