I am finishing up my self made AR lower this weekend (hopefully). I am going to put the LPK in it sometime next week after that and check it for function.
I am wanting to build an SBR upper for it and need to do the paperwork. Anything special I should do/need to know since it is not going to have a serial number?
Thanks all.
