The Traditions and the CVA share the same nipple size, so I am guessing you would get the one numbered.. 24-6100 6x1 CVA.If you want, give them a telephone call and they will be sure to get you the right one. That is going to make cleaning the rifle a lot easier, and make the barrel more stable by not having to remove pins. I think there is a cleaning kit like this offered by Traditions..yes here it is;

I've also heard of people making their own from a drilled out nipple and some fish tank plastic tubing found at a pet store. All they do is find the tubing that is the same size and they expoxy that onto the nipple.. personally I am too lazy to go through all that and I would rather spend the five bucks. Good luck with your rifle.
