I recently bought this rifle for a decent price at a Cabela's and I noticed it had this rail that doesn't appear to be factory. I'm unsure what's it for or why someone mounted it on the stock but it looks interesting. I also noticed the stock looks different from the other savage model 19s I've seen on the internet as well. If someone can tell me more about this rifle that would be great. The rail is also marked M.H.Canjar Denver. Colo.
