Travis none of the rifles I have bought for hunting have ever had to go back to a factory for any fixing. The only one's I sent back, were the rifles bought for entertainment...that was twice as I recall.
More words of experience if one is willing to read between the letters.
I like my Nula's, but a couple of them have made a drive back down to WV. If it wasn't for light I wouldn't fool with them. It doesn't surprise me the clones have problems also, due to the fact they are more mass produced.
