Piston G&G GR16 Original

This G&G GR16 original piston serves as a replacement for the standard piston that’s featured in the V2 or V3 gearbox. The piston is perfect to have as a spare and it will come in handy if one or more of the teeth on the piston in your V2 or V3 gearbox wear down and/or break off. The original piston has teeth that are made of synthetic material and it’s identical to the piston found in the G&G GR16 airsoft replica.
