SiegeTek make the strongest AEG gears on the planet. 

This is the latest generation (Gen 4) of Chromoly gears from their factory, case hardened for extreme durability. 
This full set comes with the Dual Sector gear, Spur and Bevel gears.
The DSG features an enhanced cutoff cam for snappier cutoff lever activation (and fewer semi-auto lockups), smoother dual-tappet cams and is compatible with all mechanical and optical cycle detection systems. 

The Spur is as solid as ever and will work with most standard ratio sectors and bevels. 
The Bevel gear now comes with an enhanced anti-rotation ring with a higher number of steps for the ARL to catch on as well as smoother tooth geometry for quieter operation.
 

Fully CNC machined and expertly finished, these gears will last for years to come in virtually any setup you could build. 
For absolute strength and reliability, nothing else compares.

  • These gears are a matched set and should not be mixed with other ratios. 

    DSG sets require a stronger main spring to compensate for the shorter stroke distance. We recommend a Guarder SP140 or higher. 
    Use with a weaker spring will cause pre-engagement, damage to your gearbox and will void any warranty on the gears or damaged components. 

    The tappet fin should be trimmed to a maximum length of 11mm.
    Furher instructions can be found on SiegeTek's site here.

    If you experience feeding issues, we recommend a Guarder tappet spring trimmed by 3 coils and Maple Leaf Superfeed magazine springs.

    May require some modification to fit in Krytac gearboxes.

    We recommend a thin coating of Superlube PTFE grease applied with a toothbrush. 

    When short-stroking, we recommend removing teeth from the pickup side first and then the release side in a ratio of 2:1.
