RE: Tracker II - Slug Gun
I would look into getting the 20 ga heavy barrel for it, it will come with a scope mount and add some weight to reduce recoil a bit.
I have heard of others getting tracker II's drilled for a scope rail. Some smiths will do it, some will not. I am suprised H&R will do it, if they do that would be the ticket depending on price. Have them do a triger job while they have it.
