Even in the state, you still have to register in order to own or buy a lower, without the registration, it is still illegal. You can change any upper to your AR only when they are not Class III restriction item, like SBR. Btw, I am wondering where you can get a HK416 Upper, sounds like they are not for civilian sale yet. If you are talking about the POF upper, then nevermind. Thanks.
