Hill country rifles has done some work on the Browning and gets them to shoot. They use several different tubes and they are helpful and have a pretty good reputation. There are some good barrel manufacturers that will fit and chamber a barrel too. Shilen, lilja, hart,Schneider, obermeyer area few other choices that make a good barrel. Don't really know who chambers them in that crowd but they make some quality barrels that will shoot in a couple of different grades and price levels. Mkae sure you ask if they will match your factory contour or you're going to need some bedding and stock work.there are a few drop in snythetic stocks that should work for you. I hate to tell you this but buy the time you spend the $$ for a new barrel, finishing,bedding and stock it will cost more than a new rifle. the componets are better but you may or may not be able to justify the price. Good luck hope everything works out like you want it.
