I was on PWS website today looking around. I happened to look at a Short Barrel Rifle (SBR), ~11 inches, and this was on it: "This is a factory SBR and must be ATF form 3 transferred to a Class 3/NFA dealer in order to be form 4 transferred to individuals." How does this process work? You purchase the gun and they give you a serial number You pass them the serial number and they ship the gun to an FFL of your choice using a Form 3 who sits on the firearm. You submit a Form 4 to the ATF and wait for it to be processed and approved/disapproved? Your approval is sent to you by the ATF and you take it to the FFL and pick up your firearm. Is this how it works or what have I got wrong or missed? What happens to your firearm if your Form 4 is disapproved for whatever reason? What happens if it is lost, does the FFL continue to hold firearm indefinitely? Does FFL charge for holding it by the month or ? I mean, I have heard guys waiting 6+months for approval...and thinking an FFL, like anyone, has a limited amount of space.
