SiegeTek Torque (40.91 ratio) gear set for V2/3 mechbox - High Torque Gear Set. SiegeTek spur and sector gears are CNC machined from chromium molybdenum steel (41xx steel) then case hardened. The bevel gear is warm compacted from diffusion alloyed steel and through hardened. Both hardened materials offer superior toughness, strength, and wear resistance. All of the gear teeth involute profiles are precisely calculated and accurately produced in order to provide maximum efficiency and durability. The CNC machined sector gear offers increased durability over traditional sintered sector gears. The cut-off cam is also shape optimized to decrease cut-off lever reset time, which reduces the chance of trigger switch jam. No other gear set come close in terms of quality or durability.
If it's muzzle velocity you're after while retaining a good trigger response, this gear set is for you. Easily capable of pulling back springs resulting in 500 - 600 FPS. Finally, you can complete your DMR and not have to worry about breaking gears every time you go out to play. Other upgrades we recommend for running these gears with m150 - m170+ (or equivalent springs) include: spring guide, piston, piston head, solid steel bushings, cylinder head, nozzle, high torque motor.
