Re: action/ stock
Since your 110E is a sporter barrel, the new stock would look better with the same channel inlet.
A heavy barrel channel will fit but not look very good. If you do get a heavy barrel for it someday, you can enlarge the stock's barrel channel then, not a big deal.
To be safe, measure the center to center spacing of your action screws [the ones that hold the stock to the action]. It should be 5.062", which is a long action.
