Choosing Prometheus Parts

Inner barrels

Prometheus 6.03mm inner barrels come in a wide range of lengths, from 110mm for compact guns through to 363mm and a 370mm barrel for the M4A1 MWS. Always match the length to your gun – measure the old barrel or check your gun's specification first.

Hop rubbers

Alongside the soft Purple rubber, the range includes the harder Red rubber, an extra soft flat hop bucking and a firm 60-degree air seal chamber bucking. Softer rubbers are often chosen for lower-powered guns, while harder rubbers tend to suit higher-powered setups.

Gearbox parts

For standard AEGs, you'll find hard pistons for M4 and HK-style guns, Type C and Type D stainless hard cylinders and EG gears in 18:1 and 13:1 ratios. Cylinder type should be matched to your inner barrel length, so check a cylinder chart if you're unsure. For Next Gen Recoil guns, there are hard pistons, piston heads, a hard selector plate, the Sigma trigger in black or silver, a NEO sealing nozzle and a conversion connector for the SOPMOD stock.
