About two months ago, I got a 7.62x39 NEF from a guy on Gunbroker. No special reason - I just wanted it.
Turns out that thing is stupid-accurate. Or perhaps the rifle makes *me* stupid-accurate. In any case, out of the box, I shot 20 shots into a 1.5" circle. And, I'm 62. AND, I just started shooting centerfire rifles. The only other rifle that is as accurate for me is my NEF 30-30.
If fun, low-recoil (and accurate) shooting is your goal, get one.
