The SHS POM Bore Up Silent Piston Head is designed to quiet the sound of the piston head's impact on the cylinder head. Also, the thrust bearings are designed to reduce spring tension by allowing the piston head to rotate. Finally, this piston head is ported so air from the cylinder can push the o-ring out against the cylinder walls for maximum compression. This piston head is designed for work with Bore Up cylinder components. Have this part ready when you want to upgrade or performance maintenance on your airsoft gun.
