The Modify Bore-Up Polycarbonate Silent Piston Head is part of Modify's "bore-up" kit, and is an upgrade part for high velocity AEG builds. It is constructed of polycarbonate material and has an improved air seal with the o-ring design. The front of the piston head is coated with rubber to reduce the sound signature of the airsoft replica.

The Modify series of upgrade parts are compatible with most major brands of AEG, but must be used with the rest of the "bore-up" kit.
