They want to change the law and require the lowers to be serial #'d. One recommendation went so far as to recommend that lowers be handled just like handguns.Hard to believe for some maybe, but 'home made' or 'home built' firearms have been legal to make and own since the country was founded. They have never been required to have a serial # or an identifying mark of any kind as long as they are owned and kept by the original builder. And as long as the builder keeps them in his possession there is no serial # required.
The ATF also states that as long as a forearm was built with the original intent of the builder to keep it for himself, but later changes his mind and decides to sell it, is legal. However he should be especially careful in the transaction to be able to prove his original intent was to keep it, and to obtain an identifying mark or serial # for it before the transaction.
However, I'm pretty sure that in any event that firearm transfers between owners, it is required to obtain a serial # from the ATF which is to be permanently applied to the firearm.
The preceding is based on federal law ...... be aware there are individual state statutes that may/may not enforce/contradict this.
