V1 and V2 stands for the bolt system used. Some V1 were cansoft lower, as some were full metal already IIRC. V2 bolts come with full metal body already.
As for the mags, there was a long time when only the thermold magazines were available, but since sometime the STANAG version came on the shelves in stores, and a lot of people bought them as they didn't like Thermolds.
