Every post or vid I encountered said the original mag works but others doesn't. I think I just got an opposite. The factory is the worst possible mag I have seen (and I have seen plenty). The bottom plate is loosen. I can't even load more than 3 rounds in the mag without wrestle with it. It seems marginally ok with the CProd LAR15 mags. Not live fire yet but if even snapcaps jams I really don't have much faith at all. On the other hand, it absolutely love my Troy PAR factory mag. Drop free, smooth and not a single issue cycling at all. May be I will get more Troy mags then.
