Hatsan bt65 regulator inside air cylinder

I just discovered the regulator from airgun depot that slips inside the air cylinder of the bt65. My question is will it work with the .30 bt65? Or does it need to be adjusted

You can order one from Bwalton for the .30 cal I'm sure he makes a good plenum size for it
