rifled slug barrel for Mossberg 835

[cullbuck]

I have a Mossberg 835 that doesn't get used at all since I got my Benelli Super Black Eagle. I was thinking of converting it to a slug gun for deer hunting. I'd like one with the integral scope mount. I know Bass Pro has one, but didn't know of any others. I like to have some choices.

I believe Hastings makes one as well.
