I've been looking for a used mag extension for a little while now, but I haven't found a single one!!! Anybody know if one from another manufacture will fit? I know I'm cheap!!! Just asking

Nordic components seem to be the gold standard for mag extensions on these guns. My 930 came with a choate. It's fine.
Ok I guess I meant do any of the other firearms manufacturers use the same thread for their mag cap as mossberg
