The pumps and compressors (and adapters) that you're discussing; are they like the one I have (https://www.homedepot.com/p/Husky-2...tical-Electric-Air-Compressor-C202H/312074157) that drives my nail gun and my impact wrench or is higher pressure needed?
Much higher pressures in PCP airguns. Think scuba tanks (3000-4500 psi).
And welcome to the airguns section. Ammo is cheap here. Cost of entry......not so much. But they are fun.
