I bought a Norinco M305 recently (sold my other ones a few years ago). Ordered a Boyds stock for it and the butt plate is narrower than the stock. There was definitely an issue as it was not consistent. Talked to Boyds and they sent me a new stock. The second stock just showed up and it doesn't fit either. The stock is wider than the butt plate. A good 1/8" on each side. Are there 2 different sizes of butt plates? Do they keep sending me defective stuff? What am i missing here?
