KDS: I read a Gun tests write-up on the Saiga in both the 7.62x39 and the 308. It seems that neither rifle would shoot as well with a scope as it did with the open sights. I do not recall any other negative comments about either rifle or caliber although I seem to recall someting about the stock setup. One of them came with a thumbhole stock, which a lot of folks didn't/don't like. I also can't recall what they said about the twist rate for either caliber. I would expect the 7.62 to be somewhere in hte 1:9 range and the 308 to be in the 1:12 range but ya can't never tell.
I believe that with the 7.62 version you can restock to the original AK configuration if you want but I'm not sure about the same with the 308.
I think that if you go to
www.gun-tests.com you could probably locate the article. Hope this helps. Mikey.
