One thing that will determine what you need is what do you currently have? If you already have a red dot on it then youhave a good chance of having theHorton weaver base on your bow already. You said in you above post you have a red dot so you maynot need to buy therail for yours.If the person you bought the CB off of bought it as a package deal with the red dot scope on it you may have what Horton sold as the red dot with a "integral" mount. It is basically like a red dot scope with that base you see in the link molded to it, saved Horton the cost of a set of rings. You need to take your CB and look at it. If it has a weaver style rail you will be able to see it plain as day, also you will be able to see the rings bolted to it and clamping it to your red dot. If you see no rings and no weaver rail then you need the Horton scope mount kit you posted, if you have the rail then you just need a set of one inch rings for a 7/8 weaver base. Here is the last tricky catch, but just want to cover all the bases for you. If you have a old Horton then there is a chance you may have a 3/8inch weaver base, my old super mag had one. If you have that then you will need to go to any sporting goods store and get some one inch rings for a 3/8 inch base, its the same ones for .22 cal rifles. The Excal kit will not work on a Horton CB since its mounting set up is different, buy this I mean only the bracket. But a set of Excal's one inch weaver base rings will work as long as you have the 7/8 inch weaver base on your CB. Sorry this was so long, but you need to look at your CB and see what it has on it. I don't want to tell you what to get and then you wait a week on the brown Santa and then are still unable to use it! That always sucks!!
