C'mon guys, they're just trying to do an impossible job, interpret poorly written laws perpetrated by congress, maintain licensing income from manufacturers, and keep a lid on production of non serialized weapons. You can demonize them all you want, but I think you need to keep in mind it's great we can build a weapon for our own personal use without ever having to register anything. Whining because they don't want you to have a gunsmith or machine shop do the work for you is kinda petty in my view. Pigs get fat, hogs get slaughtered, to borrow a saying about the IRS. Whether you think it's fair or constitutional or not is really irrelevant at this point, you make enough stink about it, you'll get new laws to clarify the issue and may lose the right to roll your own.
Right, we shouldn't complain about ATF making rulings that make no sense, entrapping generally harmless people to blackmail them into becoming informants (Randy Weaver), making administrative law WITHOUT congressional approval and generally behaving like thugs.
Hey, it's not their fault.....Riiiight.
BATF shouldn't even be a federal agency. Most of it's regulatory duties are poorly administered, and its enforcement arm is the most notoriously incompetent and dangerous federal law enforcement agency in existence. But hey, don't complain, they might even become more jack-booted? SRSLY?
