Legally? As long as they weren't manufactured for the charger and 10/22, they're still legal as no law says otherwise. The butler creek 25 round mags were designed before the charger exusted so clearly they were not designed for it. The gsg drums dont even fit in a charger without modification. I know about the rcmp letter but the question was what is legal not what is in a rcmp letter that has no actual legal standing. I dont want to spend time in court with the rcmp but i also dont own any non restricted rifles anymore so itsa non-issue.All of them as long as it's not a 10-22 mag
