PolarStar Complete O-Ring and Screw Set – JACK MP7
The PolarStar Complete O-Ring and Screw Set for JACK MP7 is the OEM maintenance kit for the PolarStar JACK HPA engine installed in MP7 platform builds. The JACK MP7 is a specific version of PolarStar’s JACK engine — re-engineered to fit the compact internal dimensions of the MP7 AEG body, which cannot accommodate the standard JACK geometry. Because the JACK MP7 uses different component dimensions to the standard JACK, the O-ring and screw specifications differ — this MP7-specific kit provides the correct O-ring sizes and screws for the JACK MP7 rather than the standard JACK kit.
OEM PolarStar replacement maintenance kit for JACK MP7 engine servicing. For JACK MP7 operators experiencing air leaks, declining velocity, or loose internal screws from their MP7 HPA build, this is the correct engine service kit for the JACK MP7 variant.
