Hope everyone is enjoying a sunny Friday! I have a couple quick questions in regards to registering guns. I have purchased two hand guns from local gun shops in the past and currently talking with a private seller in regards to an AR-15. I spoke with my cop friend in pierce county and he told me that in WA you don't need to actually register a gun... So my questions are: 1. If we don't have to register guns, what's the point of going to an FFL dealer? Is the main purpose for a FFL registering your gun, just in case it gets stolen its registered, as well as, FFL dealers make sure cross state/online purchases get guns get delivered into the right hands? 2. Any different guidelines for registering pistols vs long rifles? 3. Is it true that when you buy a gun at a gun store, they aren't actually registering it? 4. Later down the road say I want to register the AR-15 I bought from a private seller, do I need anything from the previous seller? Bill of sale. etc? Thanks so much for all your input!
