I have a factory made Super 16 spring-wound SBM, and want to add a 400ft magazine to it.
I will probably end up buying one from ebay I guess, primarily to save on cost.
I have several questions though
a) Do I need a specific type for it to be Super 16 compatible, or are they all the same?
what accessories / additional items do I need?
c) I saw an EM motor attachment for sale - would this help? Is it an advisable item to fit when adding the 400ft magazine?
Your help would be much appreciated.
