Badger and Tom, G3's are full auto, ergo not available, to most of us, but the HK 91 is a robust rifle, and possesses potential for better than average accuracy, it is hindered by non field adjustable sights, and a heavy trigger pull. The Cetme, in my experience is not fit very well, and generally does not work well, out of the box. I helped a friend of mine get his going and it took a lot of work. 1st failures to feed, and the original sight setting had it printing, 18" to the left, then it took 2 people to disassemble, I honed everything I could reach, to make it able to be dismantled by 1 person, and made a front sight adjuster out of an old screwdriver, and now it prints to point of aim, and the more it is shot, the better the reliability has become, but it is not in the reliable class yet, Another friend got one and it was even worse, and he sent it back to CIA, what he got back did work.
