11:45am 7 people when I arrived. Now 8 deep

Registering a lower receiver.  What is the procedure for registering a lower receiver?  I think there was confusion on my part when I went to pickup the lower receiver I ordered and had transferred to a local dealer.  Dealer asked for a permit and I told him I didn't have one...  it wasn't until I got home and thought about, realized I think he meant a long gun permit rather than a hand gun type permit.  Is that correct or am I off base here?  Thanks in advance.

What are the rules governing registration of a homemade AR15? 

1. At what point do I need to register it?
2. Does the gun need to be completed or do I register just the lower receiver?
3. Is there a minimum/maximum barrel length?

Thank  you.

Sorry but this is actually for yesterday (July 16). 
10:30 - Lots of parking underground, 1 person in line.  I was there to pickup permit for handgun and was in/out within 15 minutes
Went to the store to get the handgun
11:05 - Couldn't find parking downstairs, no side street parking or parking in front of HPD.  Circled around came back and a guy was just departing when I rolled back down.  There were 5 person's ahead but I was still in/out within 30 minutes and had a nice lunch at Lucky Belly to celebrate

I think I'll try it with my long gun permit and not with the Hand gun one...

Slightly off topic but has anyone ever used the Self-Addressed Stamped Envelope method to have it mailed back to them?  According to the HPD website:

As an option, applicants may have their processed permits mailed to them. Applicants need to provide a self-addressed pre-paid envelope, certified restricted-delivery return receipt required(available at the U.S. Post Office) at time of application for permit.

Long today. 8 people standing in line. Here at 11:15am, just to renew long gun permit. Out at 11:40am. Not bad but it was renewal

Here at 1:30pm. 5 people...registering shotgun. Out at 1:43pm. The paperwork is incredulous...

Well you got one year to get the long gun registered. In the meantime you can buy and keep the gun at the LGS.

One year to register?  You mean the approved permit is good for one year right?  My understanding is that you need to register ownership of the gun within 5 days

The gun store will only require you to show 1) photo ID (such as driver's license) and 2) your permit for the long gun (valid for 1 year).

For handguns, you have to already have purchased the handgun before you apply with the HPD so I assume you are only asking about long guns.

Otherwise, you need to show 3) proof of your handgun training or your hunter's education, when you buy at the gun store, but you then have to go through the ENTIRE process again at HPD to get the permit for the handgun (that you already paid for). Haha.

Thanks, guess the flip side is what HPD will require in terms of ID.  Will I be required to show my BC again or will they simply accept the sales slip, application, DL and of course the long gun itself?
