Huvius, what is your compaint against the Ernst's workmanship? Their's are the only new rising bite actions I have seen in completed form. And they are completely built in-house, or better yet "in-family": Max Ern and his son Max jun. do all the gunsmithing including barrel rifling and colour case hardening, while his wife Evelyn Ern does the engraving. I recommend you take a look at their homepage, in English:

At least, I do not know any other shop or family with comparable capbilities in gunmaking.
