I saw your question earlier in the day and I had hoped that someone with more knowledge on the Saiga 308 than I would answer it but here goes. I have a Saiga 7.62/39 and love it. The action is basically an AK-47 so it will be dead on reliable. What you thought was the safety was probably the button that releases the bolt cover as the safety is usually a lever on the right side. Most of these guns come with a left siderail that requires a special scope ring set up. I could not get mine to work and so I purchased a replacement bolt cover that had a scope rail on top of it. The only problem was that the rail was not for Weaver rings but the size for a .22 set of rings. Never the less I finally got it going and it shoots great and will easily outshoot both my SKS and my M-30. You can’t beat the price but they are real hard to find in one of the local shops around here. Believe me as soon as I find one in .308 I’m going to get it.
