Trop bought the rights to make the Brown 704 action and High Tech Stocks. They hired Mark to oversee the building of the new rifles. The new 704 has (at least) a 416 action body, but I don't know if the bolt itself is also SS. I sent them a message asking that question. Apparently Trop has a large amount of CNC machinery to make the actions so I'll assume that's where part of the cost savings starts. Don't know who's barrel they are using. I asked that as well.
