Outstanding GearBox Specification:

eSilver Edge Gear Box works perfectly under 7.4v to 12.5v. The current are always stable at <11 Amps in any voltages between 7.4v to 12.5v. Low and stable Amps means it drains less battery and the lifespan of the components could last longer.

Use of Advanced S.D.U.™ chips

The S.D.U.™ chipset that used in eSilver Edge Gear Box has a unique function that stop the gearbox from further damage if electric current is too high. Simply to say, electric current / Ampere will increase if there is a malfunction inside the gearbox (bad motor, damaged gears or short circuit). When our S.D.U. detects more than 5 trigger presses in exceed Amps, the whole gearbox will shut down to prevent further damage. User has to disconnect and then reconnect the battery to reboot the gearbox, we strongly recommended user to check the gearbox immediately if malfunction happened.

Micro Switch Trigger

eSilver Edge Gear Box standard comes with micro switch trigger works together with the S.D.U.™,  providing you an instant trigger response when shooting. Base on our testing, the response time of the switch is just 0.02 sec and is designed for two hundred thousand presses. With the short stroke design of the trigger, it is unbelievable fast and you won’t feel any trigger delay when shooting.

Reinforced parts

APS standard Silver Edge Gear Box has long been famous in its durability. APS eSilver Edge Gear Box further develop its strength, our electronic parts could work between -20°C to 80°C and our mechanical parts could work between -40°C to 85°C. The gear box shell is reinforced, it works under M190 spring. The rear wires of the gearbox were braided with PET sleeving provides extra protection for the wires. eSilver Edge gearbox standard comes with full steel teeth piston that increase the durability of gearbox too.

Ambidextrous design

There are several electronic gearbox manufacturers in the market but none of them come with Ambidextrous design. APS eSilver edge gearbox revolutionary made an electronic gearbox that could be used in Ambidextrous guns, it works perfectly on APS Ambidextrous rifle fully compatible with V2 Gearbox in the market.

AEG / EBB Compatible

eSilver Edge Gear Box standard comes with Non Blow Back function. User can simply switch to EBB (Electric Blow Back) function by changing the recoil plate. Switching between AEG and EBB is easy, no special tools and skills required.

Key Features of eSilver Edge Gear Box:

1) Quick Change Spring System

2) Polished and Buffed surface improves smoothness

3) 8mm Bearing Bushings, Bearing Piston Head and Bearing Spring Guide used

4) 100% TM Compatible Parts

5) Prevents Corrosion

6) Mirco Trigger Switch for instant trigger response

7) The Quick Change Spring Guide has 4 locking legs instead of 2 which is different from the existing spring guide found in the market which further secure the spring while shooting

8) Build in MOSFET to cut the power when Ampere is too high.
