That's right. Sell them on Gunbroker or on consignment at the LGS.
Answer me this: is it legal to purchase a firearm for an investment? I have always reasoned that if you buy for investment you could be said to intend to re-sell and buying with intent to re-sell in engaging in the business for which you need an FFL. If I were buying for an investment I would keep my mouth shut about that.
