Sweet, I picked up an AR15 Colt about 20 years ago but it's still new in the box. Just can't bring myself to shoot it as there are only 2000 custom shop units made.
2000 made isn't rare. Shoot that AR . Heck, I daily drive a car that only 800 total were ever made between 2 model years. 183k on it now. Things are meant to be used. I like that the standard AR mag is used in so many different guns.
