The Element Aluminum Silent Piston Head is a superb option to help quiet the sound of the impact on the included plate . Additionally, the bumper-rubber assists in reducing the impact felt. This piston head is additionally ported so air from the cylinder can push the o-ring out against the cylinder walls for max compression. If you’re trying to find a replacement part or upgrade, then this kit is certainly a solid choice for your version 3 airsoft gun.
