The only good 25 rd mags for 10/22's are the clear ones by Butler Creek. Any black colored ones are no good. Butler Creek's mags are expensive, but I got one, used it for about 3000 rounds, and it stopped feeding. I took it back to the store where I got it, without a reciept, and he gave me a new one. No questions asked. If you get two, you can clip them together side by side, for 50 rounds of shooting fun!
