Maybe this is a good place for this. I am working on developing a lower to replace the DDLES. Same principal, just a little nicer looking if you ask me. I am going to start talking to some local machine shops to see if they have any interest in producing them along with their current lineup. So if you own a shop, posses an FFL and are interested feel free to PM me.
I am still in the prototyping phase for now, and it will be quite a while before I can go much further. It is a ton of work to take an idea, design it, prototype it, test it, find a problem, solve the problem, implement design changes build another prototype and repeat.
I still have some kinks to work out, but here are some screen shots of REV 3.
