The cylinder is built using high density and heat treated steel to withstand the constant friction damage caused by the metal alloy piston head.
Special cooling groove design is added to the exterior of the cylinder, to effectively dissipate the heat caused by friction between piston and cylinder.
Moreover, the interior of the cylinder is polished to stabilize the muzzle speed and to create superb air seal effect.
