I used one, it had some issues hitting the primers on the Russian steel ammo hard enough to set them off. About 90% went off without issue, and apparently Wolff makes a more powerful spring to address the primer hitting issues. And the no name mag had feed issues, but the as usual Ruger factory mags functioned flawlessly.
If you have lots of 7.62x39 laying around, I'd say go for. If you have lots of 7.62x39 AND an SKS laying around, I wouldn't. Don't have a bulk supply of ammo for it right now? I wouldn't bother. But S/S and wood looks goooood on those guns
I'd been considering one several months ago. Already have a 1954 vintage Russian SKS, but figured a Mini-30 might be fun. Stopped by our local shop to see what there was to see. They didn't have any Rugers, but I figured ordering one wouldn't be too big a deal. The gun shop owner said ordering one wasn't any problem at all, but he couldn't recommend it. In fact he went so far as to say he hadn't ordered any Ruger Mini-Anythings recently. Asked him why, and he said their quality control had gone off the tracks lately, particularly as regards metal finishing and part-to-part fit. Guess I'll just stick with my SKS, with which I've had zero problems.
If you can get one for a good price and have access to lots of ammo at a good price, then go for it. Otherwise I would not bother.
I own two Ruger Mini 14s. I bought the first in 1979 and its blued. I bought the second in 2001 and its stainless steel. Both have been very reliable using factory magazines. I had trouble with some third party mags. The stainless gun shoots slightly tighter groups than the blued gun. I usually shoot a bit bigger than two inch groups with them at 100 yards from a bench rest. That's my personal limit with iron sights on any gun, so I don't know if the guns are more accurate than that or not. I'd guess not.
