I only own one red rifle, a standard Russian sks, so forgive my ignorance here. I've been following various threads about red rifle mods and the various 'ak pattern' rifles that are either available now or on the way soon. My question is a basic one and has likely been answered before. What's the difference between the VZ 858 and CSA model(s)? Is one made to a higher standard? Is a VZ/CZ the same as a VZ? Is it just a matter of availability?
