Similar to many people who work on/duracoat/paint their friends guns without having an FFL.
Or the ever maligned 'private seller' at the gunshow.
Being 'engaged in the business of', according to all other examples that the BAFTE has ruled on, requires that a business (or individual) is, in fact, engaged in making a living by engaging in the selling, modifying, personalizing firearms.
Hell, I could make 50 AR's (or any other type of semi-auto weapon) from scratch, and as long as I don't sell them, I don't need an SOT, as I'm not 'engaged in the business' of making and selling firearms.
That is why there is a good market for 80% lowers.
