So Guys I just communicated with Highland Outdoors the importers/ dealers of the Nemesis PCP and they inform me the PCP has different guts to the C02 version, and its designed to operate on HPA.

Quote from Highland Outdoors this afternoon. ""Hi Bill, Thanks for the message. The Nemesis X PCP uses different internals designed for the higher pressure of PCP. Co2 works on a much lower PSI than PCP.""

This little carbine just keeps growing and growing on me.
