I know UW is a lefty but I am not sure about anyone else.

Anyway my dad is wanting an AR now and he shoots left handed. If anyone knows of where I could pick up the stuff for building a lefty upper that would be helpful. I knew about (I think Stag) but they got in trouble a few years ago if I am not mistaken.

Also I've never done a basement build, but that's what my dad wants. Something cheap but reliable. Info on stuff like the cheapest but most reliable RDS and all that would be helpful.
