So I was at my local gun shop today to pick up my completely stripped lower reciever today for a build. I told the gun shop employee my plans for the build, which were to make a dedicated .22lr pistol and possibly sbr it down the road. He then proceeds to tell me that I will have to bring it back in to have it registered as a pistol, because it is now considered a "restricted firearm". I have several ar lowers that I bought as stripped lowers and made pistols, one 80% lower that is a pistol without any serial numbers or markings on it. I have never heard of this so called new law until recently and was wondering if anyone else has any input for me. Thanks and sorry for the long post.
