CNC machined Cylinder Head from Nuprol coupled with a professionally installed Air-Pad polyurethane buffer pad.
We use Gorilla Glue Gel super glue to ensure a perfect bond in even the highest stress builds.

This unit fits perfectly with Prometheus and PDI Steel Cylinders and seals exceptionally well with Lonex and Prometheus Recoil Air Nozzles. The buffer pad dampens the piston head impact and partially corrects the Angle of Engagement.
