Been thinking about building one myself and I think I found some parts, and websites to get them for a build of this, felt like sharing them for opinions.

Personally I think that these parts are pretty close to the actual honey badger design, the only thing I think may be a problem is mounting that stock, but its not a big hurdle, just some modifications. Any opinions or ideas?
