Union Fire High Speed Gear Set 16:1

The Union Fire High Speed Gear Set 16:1 from Bullseye Country Sport is a performance-focused gearbox upgrade designed for airsoft AEG builds using Version 2 and Version 3 mechboxes. Manufactured from CNC-machined steel, these gears are intended to provide improved durability, smoother operation and faster cycling performance compared to standard ratio gearsets.

Featuring a 16:1 gear ratio, this set sits in the popular high-speed category, offering quicker trigger response and increased cycling speed without becoming as extreme or demanding as ultra high-speed ratios. This makes the gearset an excellent option for players wanting a more responsive rifle while still maintaining solid reliability when paired with suitable internals and proper setup work.

The CNC steel construction helps provide improved strength and wear resistance under repeated use, while the precision machining is designed to support smoother gear meshing and more efficient gearbox operation. Proper shimming, motor pairing and compression setup remain important for getting the best overall performance and lifespan from any upgraded gearset.

Compatible with standard Version 2 and Version 3 gearbox platforms, these gears are suitable for a wide range of common AEG builds including M4 rifles, AK platforms, MP5 variants, G36 systems and many other popular airsoft rifles where improved trigger response and faster cycling performance are desired.

The 16:1 ratio has become a particularly popular middle ground amongst upgrade builders because it offers a noticeable improvement in responsiveness without requiring the extremely demanding setups often associated with ultra high-speed DSG or very low ratio builds.

At Bullseye Country Sport, we reckon gearbox builds always start innocently enough… then suddenly you’re explaining to your wallet why you apparently needed “just one more gearbox upgrade”.
