Modify quantum double cycle gear set 

QUANTUM GEAR SET
MANUFACTURER MODIFY
FOR VER.2/3/6 GEARBOX

THE QUANTUM DOUBLE CYCLE GEAR SET FEATURES A SET OF TEETH OF EITHER SIDE OF A SECTOR GEAR WHICH ALLOWS TWO SHOTS PER GEAR CYCLE, DOUBLING YOUR RATE OF FIRE.
A HALF-CYCLE CUT-OFF SYSTEM IS ABLE TO RETAIN SEMI-AUTOMATIC FIRE WHICH IS USUALLY VERY TRICKY TO PULL OFF WITH A SHORT STROKE STYLE SYSTEM.
THE SECTOR CLIP IS SHAPED IN SUCH A WAY TO DELAY THE RELEASE OF THE TAPPET PLATE TO AVOID ANY FEEDING MALFUNCTIONS. 
A SPRING GUIDE SPACER PRE-LOADS SPRING TO COMPENSATE REDUCED PISTON STROKE.
MODIFY RECOMMENDS THIS SETUP ONLY BE USED WITH A 363mm INNER BARREL OR SHORTER DUE TO THE REDUCED AIR COMPRESSION THAT THE SHORT STROKE SYSTEM PRODUCES.
THE TWO-SECTOR GEAR IS COMPATIBLE WITH MODIFY SPEED / TORQUE / STOCK RATIO GEAR SETS.
