A friend of mine, (Vietnam Veteran), who hates using computer has requested I ask this.
back in the 70s he bought one of those "drop in m16 conversion kits" which I'm assuming the proper term is lightning link, mail order from a magazine. Is it legal to install this into his Colt SP-1? He says they were available for sale in abundance back then. Do they have to be registered with the ATF now or are they ok as purchased back then???
secondly, if it needs to be registered (which he says he would happily do if needed) are there major modifications needed to be done for this "drop in" kit??
He and I would greatly appreciate any help we can get on this subject matter.
Thanks in advance,
Ike
