Let's hope that If these (now only sold with new Mini 30s) are not manufactured by Ruger, then at least they might be Promags.
How do we know that Ruger built them?
After the election was the first time when Ruger ever sold their larger Mini 14 magazines (20-rd.) to the public.
Lots of confusion is created at "Perfectunion" by people referring to magazines without ever stating which Mini rifle (14 versus 30 versus 6.8) is being discussed.
Many Gunbroker sellers have used the words "factory mag" for aftermarket mags (legally correct), most of which are unreliable or simply don't feed at all.
