Cylinder Sets
Cylinder Set is for all-purpose, and can be set in all types of Marui GearBox. It features a port, which creates negative pressure inside the cylinder when the piston goes back, resulting less possibility of malfunction to loading system even when using 0.25g or heavier BB bullets.
Also, this set remarkably improves the grouping, which we most value. It realizes only 1m deflection in the muzzle velocity, just by assembling this set with cylinder grease, which means that just setting cylinder set is more effective to realize better grouping than giving a normal barrel tuning.
In addition, N-B, as in the name, means N-B plating plated in Cylinder, and the electrolyzed plating features its surface hardness, resulting a stable and long-term use.
