Just fitted a harris 9''-13'' swivel bipod to my synthetic stock on my 202 outback. Put it off for a long time but drilled hole in the stock and fitted a synthetic stock adaptor by harris and its a great job. Theres a metal plate inserted inside of the stock which the bipod swivel screws into. Bed it down with epoxy resin as instructed and you're home and dry. No excuse for missing now is the only problem!
