My concern is that it may cause the supply of 80% frames and receivers to dry up. As it stands today, I can buy a completely finished AR-15 lower receiver or 1911 frame for significantly less than what it would cost me to buy an 80% lower or frame. The companies who make those can charge a premium because some buyers are willing to pay a premium in order to build a completely legal firearm that doesn't have to go through an FFL.

Once everything has to go through an FFL, many of those buyers will likely just opt for a 100% lower or frame, and the 80% suppliers won't have enough business to stay in business.
