I put a nice "olde type" crescent butt plate on my Henry Mares Leg that I put a full length stock on. Looks really cool, adds to the period look. Got mine from Brownells.
Also put on a flip up tang sight (Marbles) so that even with a 12" barrel, I still have a 18" (or thereabouts) sight radius. That gives up nothing when it comes to accuracy and makes a handy carbine.
I know mine is just a Henry rimfire, but its what I can afford.
In its regular Mares Leg configuration it is a lot of fun, but kinda useless. Add a real buttstock to it and you have a supper handy bush carbine. With the Rossi in chamberings like .44 Magnum you have a viable big game gun.
