We wanted to say something intelligent about these fancy piston seals... but we could not quite manage it on our own... so we thought we may as well ask the man who designs them to say something. So, Steve Pope of V-Mach said...

This Seal is cold-formed and manufactured from advanced materials, which possess valuable properties that cannot be replicated by the usual injection moulding process.

Benefits of the Hybrid C-Form Piston Seal include:-

·           greater efficiency, on average requiring one less coil of mainspring for the same muzzle energy than earlier Powr-Pulse versions

·            improved consistency through wide temperature variations

·            improved piston acceleration, resulting in faster lock-times

·           greater resistance to dieseling or minor surface damage

·            excellent resistance to wear, even after extended use
