Accelerated wear
Unstable FPS
Mechanical damage

By choosing quality parts from brands such as Retro Arms or Guarder, you improve:

Structural strength
Better shimming and smoother rotation
Higher reliability with heavier springs
Consistent performance under load

For high-speed or high-torque builds, the use of strong gears and reinforced gearbox shells is crucial.

Compatibility and alignment

AEG gearbox parts differ depending on the type of gearbox. The most common are:

V2 gearbox (widely used in M4 platforms)
V3 gearbox (e.g. AK platforms)

It is important to always check which version is suitable for your replica. Parts such as gears, shells and tappet plates are not universally interchangeable.

For players who work with electronic trigger units or MOSFETs, a stable and correctly shimmed gearbox is extra important to ensure cycle consistency.
