And I still know I have all the mechanical abilities of a rotten orange!I would have to tell you to look at the BATFE's website. That seems to be a plethora of info on anything relating to firearm rules and regs.
As a side note, I would pay $20-$30 for a set of detailed plans to build my own mag(s). And yes, I know how to make springs.
3-D printers don't use durable enough plastic.How do you guys feel about plastic? I use plastic waffle style mags on my AK.
It seems as though it would be trivial to produce waffle style plastic mags with a 3D printer once design specs were worked out. If you don't want to get a 3D printer, there are companies that will produce any 3D plastic design you send them. Then you'd just have to adapt the spring from something else, or make them yourself.
It would seem to me that there'd be a niche market for these in 8 or 10, and 15 or 20 round configurations. The only difference would be the length of the mag body & spring.
