When it comes to upgrading your AEG, there is no getting around Prometheus. As part of the Japanese giant LayLax, Prometheus has for years supplied the parts serious techs swear by. Their focus is simple: the perfect balance between choice of materials and precision. We recommend Prometheus if you want Japanese reliability and a noticeable difference in range and accuracy on the field.
The legendary EG 6.03 mm barrels
The Prometheus EG series is a much-copied precision barrel:
Stainless steel: Unlike cheaper barrels, Prometheus barrels are machined from stainless steel, giving an extremely hard surface that does not corrode and is easy to keep clean.
Precision tolerances: With an internal diameter of 6.03 mm, you get the perfect balance between higher muzzle velocity and the air cushion that stabilises your BB.
Finish: Every barrel goes through strict quality control in Japan to ensure a mirror-smooth inner surface.
The purple hop-up bucking: A living legend
You can hardly say Prometheus without saying "Purple Bucking":
The purple bucking: Known for its excellent grip on the BB and consistent spin, even in changing temperatures. It is often the first upgrade we recommend for a new rifle.
Reinforced gearbox parts: Prometheus supplies everything from the well-known "Hard Gears" to precision shims and pistons, built to withstand thousands of shots at high rate of fire with LiPo batteries.
Air seal components: Their nozzles and cylinder heads make sure your system is 100% airtight, so every millilitre of air is used efficiently.
Looking after your Prometheus parts
To keep Japanese top performance, the parts need proper treatment:
Cleaning the barrel: Stainless steel is durable, but it still needs to be kept clean. Use a cleaning rod with a soft cloth from our airsoft cleaning and maintenance collection.
Hop-up care: Avoid getting silicone oil directly on your purple hop-up bucking, as it reduces friction and therefore the effect of your hop-up.
Pair with quality: A Prometheus barrel performs best when paired with a ProWin hop-up chamber for the ultimate air seal.
