I have a Long Branch that was given to me as one of the worst bubba sporter jobs I've ever seen. Complete with a rubber shotgun butt plate mounted upside down. And that was one of the better features of this dude's "sporterization".
I got all the wood and most of the metal from Numrich(Gun Parts Corporation). I had to cut down some of the muzzle end hardware because bubba had sawed off the end of the barrel. But it came out as a reasonablely respectable looking rifle. And shoots as good as I can hold it off-hand. When I miss, it ain't the rifles fault. May have to get it out of the safe today just for the heck of it.
