Hi guys, new to the forum, but not to the firearms world. Anyways, I was wondering if FFL/shops can legally perform background checks using Form 4473, or more specifically, the NCIS e-check system, for people NOT buying a firearm from the business? In other words, if I was engaged in a private FTF sale could I ask(expecting to pay a small fee for the service) an FFL to perform a background check on my purchaser? I realize the FFL would probably required to retain the paperwork as if this was a firearm purchase from the FFL, but all that aside, can the FFL engage in the business of doing bg checks as a 3rd party service? Thanks for any info guys, if I don't find what Im looking for here I guess my next step is to call the ATF. However, if this sort of business is acceptable, any FFL here want to engage in a partnership with a software company to develop a solution to offer this as a service in a cost effective way? I foresee this becoming a service that would NOT require the people making the transaction to be in your shop allowing users of your service to be anywhere in the state/(country?). If intriquing, please PM me and I can give detail on my qualifications. Mods, please don't lock this post due to thinking this is solicitation or advertisement. My intent here is to really find out if this is within the boundaries of an FFL.
