Got bit by the retro bug over the summer and built up an M16A1 clone. All parts minus the barrel and lower receiver are USGI Colt parts. NODAK did an AWESOME job on the replica receivers. Upper is late 70's so the 3 prong is technically incorrect, but I loved the look.

I've fallen in love with how light, and just flat out accurate this little rifle is. It goes out on every range trip.

I've got a slabside SP1 stripped upper sitting in the safe that's up next, when I get the time and funds.
