If they did that, they wouldn't be able to say "This is a Remington 700 ADL" or whatever. They would have to give it a different model number. If they sold "cheap versions" with the same model number, both the manufacturer and the distributor would be subject to claims under various state laws prohibiting deceptive trade practices. If you see a 700 ADL at WalMart, it is going to be of the same quality as a 700 ADL at some mom and pop gun store.
