Just ordered the parts from Brownells today to make my own XS Sights type scope mount for my '94 Big Bore.
Cannot see paying $55 plus shipping. Parts are less than $18 so far and I have to get the front receiver ring drilled and tapped (Had to anyway with the XS), so that is a wash.
I plan on posting all the info in an article on my web sight, once parts arrive. I plan on mounting my red dot scope up front.
I know others have done similar things so it should all work out.
