Prometheus Aero Cylinder Head Ver. 3

Duralumin cylinder head with a tapered air inlet for Ver.3 gearboxes

The Prometheus Aero Cylinder Head replaces the stock cylinder head in a Ver.3 gearbox. Its tapered air inlet feeds air into the nozzle more evenly, and the O-ring on the collar keeps compression sealed even behind stiff springs.

Construction and accessories

The cylinder head is machined from duralumin and hard anodised, so the surface stands up to the air nozzle travelling back and forth on every cycle. Tight machining tolerances keep the nozzle centred, and the fitted O-ring seals the joint to the cylinder. This version fits Ver.3 gearboxes as used in AEG of the AK, G36 and MP5K series. Contents: 1 cylinder head.
