Open Pandora’s Box<\/strong>\u00a0and\u00a0let your enemies feel the wrath of the most durable gears<\/strong>\u00a0ever made!<\/p>\n

CNC gears PandoRA 20:1 with 4mm shafts<\/strong>\u00a0from\u00a0RetroArms<\/strong>\u00a0are\u00a0crafted from a single piece of steel<\/strong>\u00a0through the most precise\u00a0CNC<\/strong>\u00a0machining.<\/p>\n

Withstand the strain of an M210 spring<\/strong>\u00a0and are available\u00a0for almost every\u00a0AEG<\/strong>\u00a0guns, including\u00a0Marui NGRS<\/strong>,\u00a0SR-25<\/strong>, or\u00a0DSG<\/strong>.<\/p>\n

PandoRA – Gears endowed with all gifts!<\/strong><\/p>\n

On the airsoft market, numerous CNC gears exist, but not all are of high quality and truly durable! At\u00a0RetroArms<\/strong>, they decided to go all out and crafted gears that are entirely CNC machined from high-quality hardened steel for\u00a0AEG<\/strong>\u00a0airsoft guns.
Named\u00a0PandoRA<\/strong>, referring to\u00a0Pandora from Greek mythology (meaning “Endowed with all gifts”)<\/strong>, these gears also bring you all the gifts (advantages) of the\u00a0most durable gears<\/strong>\u00a0on the market.<\/p>\n

These gears are\u00a0made entirely from a single block of solid steel<\/strong>, so\u00a0no assembly from multiple parts!<\/strong><\/p>\n

Before production, they were tested\u00a0with an M210 spring<\/strong>\u00a0up to\u00a010,000 shots<\/strong>\u00a0in\u00a0CNC RetroArms gearboxes<\/strong>\u00a0without any signs of wear. They\u00a0perfectly complement\u00a0RetroArms pistons.<\/strong>
The gear set includes:\u00a0Sector\u00a0Gear –\u00a0Spur Gear –\u00a0Bevel Gear.<\/strong><\/p>\n

RetroArms offers the following gear ratios:<\/p>\n

1. Gear Ratio 20:1
<\/strong>a)\u00a0with 3mm shaft
b)\u00a0with 4mm shaft
c)\u00a0SR-25 with 3mm shaft<\/p>\n

2. Gear Ratio 16:1
<\/strong>a)\u00a0with 3mm shaft
b)\u00a0with 4mm shaft
c)\u00a0TM NGRS with 3mm shaft\u00a0(only for\u00a0EBB guns\u00a0TM NGRS<\/strong>)<\/p>\n

3. Gear Ratio 13:1
<\/strong>a)\u00a0with 3mm shaft
b)\u00a0with 4mm shaft<\/p>\n

4.\u00a0Gear Ratio 10:1<\/strong><\/p>\n

5.\u00a0Gear Ratio DSG\u00a0<\/strong>(Dual Selector Gear)<\/p>\n

Remember that gears with 4mm shafts can only be used<\/strong>\u00a0with\u00a0bearings with a 4mm<\/strong>\u00a0inner diameter<\/strong>, and you will also need\u00a04mm shims<\/strong>\u00a0to achieve\u00a0proper gear shimming.
<\/strong>Also, don’t forget to check\u00a0the correct angle of engagement of the piston gear with the piston\u00a0(AOE).<\/strong>
Standard gears and readily available bearings are made with 3mm shafts.<\/p>","protected":false},"excerpt":{"rendered":"
