Last I heard, my SLR-105 is shipping today. With that in mind, I figure that I had better get some mags to load up all that 7N6 that will be arriving about the same time as my rifle. I've been looking around and I'm seeing quite a selection of mags, but I don't know what to look for. Bulgarian, German, Russian, Steel, Polymer, Plastic(?), Bakelite, Circle 21, Circle 10, black, brown, brick, saddle, etc. the list goes on. Does anyone have any input as to what to get and/or what to avoid? From your experience, are most of these mags used? Should I be looking for new? Thanks.
