Bohica is a manufacturer. The lower started life as a solid piece of aluminum. Very similar to the Palmetto Olympic lowers. The hole lower is milled, not forged or cast. The look stout and the lines are slightly different than a current manufactured lower. They are definately pre-ban. I beleive the company went undewr or closed its doors way before the ban. I would like to own it. Get me a picture or a scan of each side and we will talk.
