This is the cheapest I've seen some of these for very long time. BX-25 magazines for your 10/22 for less than $17 is a great deal. And Mini 14 20 rounders for for $20 is also a pretty good deal.
I only wish they had the LCP 7 rounders or MK II's for sale. In my experience, OEM Ruger magazines are the only ones that fit properly in my various Ruger firearms, I've gotten rid of all aftermarket Mini-14 magazines, and almost all of my aftermarket 10/22 magazines (I got some in a trade a while back and they seem to feed reliably so I haven't dumped them like I normally would).
