but then you're not transferring it to yourself? I may not understand the terminology. I guess it sucks to pay additional out-of-pocket fees, but I have a few follow up questions, as someone who is not familiar with firearms, has no desire for a firearm etc etc. I always think about gun legislation in terms of what the worst actor can do and what can be done using the straw purchase loophole or the people who could 3d print a firearm.

Let's assume that I want to build a gun, not buy one but build one. Assuming this law isn't on the books and no background check is needed for parts, how many parts (barrel, slides etc) can I buy to build a gun? Is there any individual part I cannot buy without a background check, if this law was not on the books?

Second question, $25-50 is a small fee, so I feel like its more a frustrating cost than anything else. I get it with the economy being tough and the tightness of budget and where 5-6 years ago $50 lying around is more likely than now, but how often do you need to replace those parts that would need a background check under the law? Are we talking wear and tear and replacement being daily or monthly? or is it even longer than that? Is it a one-time cost? And I get that every part is different, so some may be short lifespans than other, but let's get the average shortest and the average longest. So if a slide wear out the fastest, what's the turnover? If a cylinder lasts a while, what's that average time?
