CNC Steel Gear set PandoRA - DSG (3mm)

On the airsoft market, numerous CNC gears exist, but not all are of high quality and truly durable! At RetroArms, they decided to go all out and crafted gears that are entirely CNC machined from high-quality hardened steel for AEG airsoft guns.
Named PandoRA, referring to Pandora from Greek mythology (meaning "Endowed with all gifts"), these gears also bring you all the gifts (advantages) of the most durable gears on the market.

These gears are made entirely from a single block of solid steel, so no assembly from multiple parts!

Before production, they were tested with an M210 spring up to 10,000 shots in CNC RetroArms gearboxes without any signs of wear. They perfectly complement RetroArms pistons.
The gear set includes: Sector Gear - Spur Gear - Bevel Gear.

RetroArms offers the following gear ratios:

1. Gear Ratio 20:1
a) with 3mm shaft
b) with 4mm shaft
c) SR-25 with 3mm shaft

2. Gear Ratio 16:1
a) with 3mm shaft
b) with 4mm shaft
c) TM NGRS with 3mm shaft (only for EBB guns TM NGRS)

3. Gear Ratio 13:1
a) with 3mm shaft
b) with 4mm shaft

4. Gear Ratio 10:1

5. Gear Ratio DSG (Dual Selector Gear)

Remember that gears with 4mm shafts can only be used with bearings with a 4mm inner diameter, and you will also need 4mm shims to achieve proper gear shimming.
Also, don't forget to check the correct angle of engagement of the piston gear with the piston (AOE).
Standard gears and readily available bearings are made with 3mm shafts.
