The Modify Bore-Up Aluminum Piston Head is part of Modify's "bore-up" kit, and is an upgrade part for high velocity AEG builds. It is constructed of aluminum 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.
