These Butler Creek 25-round magazines are great for the Ruger 10/22 rifles. I have purchased several for my Ruger SR-22 rifle. The steel-lipped versions seem to work better than those with the plastic lips. My one magazine with plastic-lips had a few feed issues to start with, but is working fine now. The mags with steel-lips have been flawless. I highly recommend these.
