The one issue I have is with the plastic rotary magazines. They break, are typically hard to find and many times don't feed correctly. New magazines just recently became available and I bought one. Rounds would feed smoothly if I worked the action slowly but would bind if I worked it quickly. The vendor replaced it but the replacement has issues if I load it complete with 5 rounds. If I just put three rounds, it works fine. Its pretty frustrating to deal with.
Tmitch, have you had issues with your magazines?
No I haven't. I bought one extra when I bought the rifle and both have worked, and are still working, without issue. I remember an advertisement or article I read many years ago concerning the plastic (Makrolon?) magazine where the author gave it a good whack with a sledge hammer and it didn't break and functioned afterwards. I haven't tried that, don't think I will.
