Hello all,
I've always been intrigued by Sig 551/552 and 556. I'm finally considering purchasing one. I found a Sig 556 Classic with the collapsible and folding stock. I was wondering what serial number to avoid? I was reading it was the 1st gen's that had issues with canted sights and bolts? Or was that the 2nd gen? The Serial Number on this 556 Classic starts with " JS0342XX" Which I believe to be a 2nd Gen.
