Over the holiday, I sold a Ruger 10/22. I have a few mags sitting around that likely won't see any use for a while.
One used Butler Creek 25 round Hot Lips mag
Two used Ruger 10 round factory mags
The Butler Creek has seen a good bit of use, but fed reliably for me. The Ruger mags are almost brand new and have only seen a hundred rounds or so each.
