I have a non-folder for the mini-14. It is a good stock for the money.
My biggest beef is that the knurls/checking is actually too rough to hold confortably. On mine, I have solved this by covering the grip areas with stong black duct tape. The fit w/ factory liner for the mini is tight and the overall length for eye relief not bad. My father-in-law has one for his carbine and it is about the same.
It's not a top-notch thing for everyday use, but fine for most uses.
