I guess each county had a different policy? It should be the same.
Barreled action should be fine. Make, model, action, cal, barrel length.
As for the stripped lower I think once you have turned it into a carbine or rifle then you should go back to HPD to add to the registration. Caliber, barrel, length, and action.
( could be bolt action 50 cal 28" barrel for all I know)
I registered a stripped AR lower and once I completed it , I went in to have HPD redo my registration. 5.56 cal 18" barrel, semi auto. If and when I get a 22lr upper assy i'll add that too.
Its a just in case - If I get into a accident coming to or from the range and things go everywhere? My registration paper says I have a completed rifle and thats what was with me.
