I've often thought that something like that would be cool. You could adapt a Vernier tang site or screw on one of those Malcom reproduction scopes. But then you'd have to go for buffalo as they don't hang out in the thickets of manzanita, deer brush and whitethorn. In regards to the latter, I used to do field surveys for the US Forest Service and would tell people that beating through the brush caused you to loose three things. The first thing you lost would be your compass as the lanyard always got hung up on a snag. The second thing would be articles of clothing and, when the going got particularly nasty, the third would be your sanity. I hate brush fields!
