Aside from S&W, I would think winchester or remington should be seen imporvements are ammo sales are up.
The bad thing is there is not a whole lot you can invest in, remington is owned by cerebus, winchester by OLN (Which is sucking wind), Maybe a small bonus walmart, bass pro is privately held. Along the same lines, safe companies are booming, but I can not find any public companies you can buy into.
