I got an old plinker plus no problems. I think its pretty accurate @ 200 yards never missed the black with iron sights. I would buy another without any reservations.
Bought mine slightly used (less than 200rds fired) from a buddy in college for a good price. I've put maybe a thousand more rounds through it and have never had a problem.
I've made a couple of mods to it and am now working on the next AR build
