More truly DIY designs that use non gun parts. This future-proofs against tyrannical legislation. As mentioned by an earlier poster, hybrid designs with a bit of metal work/reinforcing for longevity. I still think truly DIY designs in 9mm and 5.56mm are the holy grail, to go with 12g and 22lr. The most common, accessible calibres in other words.
