ZCI CNC 16:1 Airspeed Gearset – High-Performance Steel

The ZCI CNC 16:1 gearset is engineered for players who demand speed and reliability in their AEG builds. With a 16:1 drive ratio and premium CNC steel construction, this gearset transforms your gearbox into a high-velocity, rapid-firing platform ideal for close-quarters skirmishing and sustained suppression roles.

Key Features

• 16:1 drive ratio – exceptional RPS potential with lightweight springs
• CNC-machined steel construction – precision tolerances and durability
• Up to 40 RPS capability – achievable with M120 spring or lighter
• Ver. 2 & Ver. 3 gearbox compatibility – fits most AEG platforms
• M110–M150 spring range – flexible tuning for your build

Real-World Use Cases

This gearset excels in CQB environments and suppressive fire roles where rate of fire matters. It’s equally suited to high-ROF builds for DMR conversions using heavier springs (M120+). The precision CNC machining ensures minimal wear and consistent performance through long gaming sessions.

Technical Specifications

• Drive ratio: 16:1
• Material: Steel (CNC-machined)
• Maximum RPS: 40 (with M120 or lighter spring)
• Spring compatibility: M110–M150
• Gearbox version: Ver. 2 & Ver. 3 only

Compatibility & Upgrades

The ZCI 16:1 gearset fits standard Ver. 2 and Ver. 3 gearboxes found in M4, M16, AK, and G3-pattern AEGs. Pair it with a quality motor (18–22 TPA recommended for this ratio) and appropriate spring to optimise performance. Aftermarket shimming and lubrication are advised for best longevity.

UK Legal & Site Notes

As an internal upgrade component, this gearset carries no UK legal restrictions. However, ensure your final AEG’s FPS complies with your site’s chrono limits—typically 328 FPS with 0.20g BB on most UK sites. Check your skirmish venue’s rules before attending.

Invest in precision engineering for your airsoft platform. The ZCI CNC 16:1 gearset is your foundation for rapid-fire reliability.
