When the Remington conversion was first announced it was supposed to come with the percussion cylinder as well, and some gun mags printed articles about it with both cylinders. But when it came to production, Uberti found that it took too much time to fit both cylinders, so the guns were sold without the percussion cylinder. You could order the percussion cylinder (the new larger size) and fit it yourself. I think a very few of the new guns were shipped with the percussion cylinder. Consider yourself lucky!
