Well they are now because of the title....... To my question: I really enjoyed tinkering with the SKS and it's the third gun I've bought that needed 'help' I took one to a gunsmith but in hindsight I could have done that one myself too. Now I've got 5 guns that I could potentially sell for more then I've paid for them. Either that or trade. Question is how many "hobby" sales or trades can you do before you're going to need a C&R or a full blown FFL? When I'm bored I'm sometimes thinking about starting a side business. But what's the cutoff point between hobby and business?
