I saw a lot of Portugese model 70's which had the extractor groove, in the bolt head, located too far forward. This reduced the amount of primary extraction. In some cases, it was almost as bad as on a new Remington 700. Apart from this obvious flaw, they were very nicely made rifles. One other issue I have seen consists of ripples in the bore. I have not had a close look at a real recent example but I hope they fixed the extraction issue. GD
