Matrix Airsoft Gear

This set is designed for standard Version 2 and Version 3 gearboxes, which covers the vast majority of M4, AK, MP5, G36, and P90 platforms. If your rifle uses a proprietary gearbox design, you should verify compatibility before installation.

These gears are rated for springs up to M135. While they are built from durable, heat-treated steel, pushing beyond this rating may cause premature wear or failure.

The 18:1 ratio is the industry standard for high-torque builds. It provides a reliable balance between trigger response and rate of fire, making it an excellent upgrade over stock gears for most general-purpose airsoft rifles.

Yes, the precision milling on the sector gear reduces vibration during the firing cycle. While it won't make your AEG silent, you will likely notice a smoother, less 'whiny' sound profile compared to standard cast gears.

In most standard gearboxes, this is a drop-in replacement. However, because tolerances can vary between different brands of gearboxes, you should always check your shimming and ensure the gears spin freely before fully assembling the gearbox.
