If they don't say Ruger on the bottom of the mag. plate, they aren't factory items. I have an assortment of 30-round aftermarket mag's for my old 183-series Mini-14 that work as well as the factory items, but I must admit they are pre-'94 ban magazines. With the availability of 20 & 30 round factory mag's improving along with the lower pricing, it doesn't make any sense to not go with them, especially when they are on Sale. Using aftermarkets is a crap-shoot at best.
