I've had one of my 16" 308 saigas for quite a while now I just bought another one off gun broker for a really good deal. When I started to compare the two the newest one felt a bit heavier, after a few I measured the Barrel diameter and sure enough it's a bit thicker than my old Saiga 308. As it wasn't hard enough to get some hand guards to fit my old one with out a lot of custom work now I've got an even thicker one to deal with..what is the deal with this any info would be much appreciated
