Sourdough, I guess I fell off the same truck.
I'm to the point where I almost anticipate some of these failures, but they never seem to happen. (somehow I feel I'm over due).
My NEF rifles have been not been "abused" per se, It's just that I just don't seem to give them as much consideration as I do a rifle that I have paid two / three times as much for, and I'm sure that is not good!
None have been through a "break-in" stage, all of them shoot as good, some better, than any of my other rifles, and not one has ever had a single problem. None, Zero, Zilch.
I guess ignorance can be bliss. I'm not complaining, just stating a simple fact that, in this little rifle, you get a lot for your money. I personally know several people who have, through their own choice, sold / traded their other "brand name, high dollar" guns off in favor of these little jewels. Of course, they will never replace those "other" guns, but they certainly give more bang for the buck than anything I'm aware of.
This is all just my opinion, and others experience may differ a bit, but from what I hear, service is fairly prompt, and the warranty work seems to cover a lot.
