Crosman needs to find their new place in the airgun world, in the low end of the price point in airguns they are soundly outdone. They would be very late comers in the high end market, and I'm not sure the degree of quality necessary is in their wheelhouse.
Here is a video I just made on the Nova Vista Liberty
I've filled my Liberty to 4200 from my YH just to try my compressor and the Liberty.Since I have a SCUBA tank that I keep at 3k psi now that I have my YH it's more convenient to fill PCP's to 3k & 2k.Rarely will the Liberty see a fill over 3500.
