For more than 25 years, we know what you like about airsoft.
A set of 5 nylon washers for AOE tuning. The angle of engagement (between the piston and piston gear teeth) is important for the reliability of the weapon.
The washers must be placed between the piston and the piston head. The thickness is about 0.95 mm.
