Prometheus AEG Gearbox Stainless Steel Hard Cylinder (GG10-09)

This is a low-friction, high-quality Stainless Steel cylinder by Prometheus. The ridges are designed to dissipate heat and reduce friction resistance due to the expanding O-ring caused by heat.

The concept of different cylinder sizes is to A: Achieve a more stable shot by matching cylinder size to barrel length.  B: Although just putting type A in all guns will work, larger cylinders have more air and require more time and force to clear the cylinder of air, not installing a larger cylinder than you need can DECREASE ROF and return to the rest speed of your piston, this in-turn increases ROF and reduces potential piston damage from gear speed/piston speed being out of sync.  As you can see fine-tuning your cylinder option can have lots of positive benefits on your gun build.

As a general rule 363mm barrels can use anything from A - D, so you have a lot of room for fine-tuning the perfect setup for you.

Fits: Any Tokyo Marui that takes a normal-sized AEG cylinder.  Please choose the type based on your tuning needs.
