I had a deluxe model at one time and it did not have a band, wasn't supposed to have one, is there markings or indents/grooves on your stock to indicate there should be a band fitted, perhaps you have the deluxe model, if you google it you may see a similar model to yours.
I had a similar problem to you, I had a cheap scope on it, I changed it and that was it cured.
