Slightly less pricy on a Buy Now but possibly modified as well:

Saw it looking at their listings earlier today. I've bought from 3157Mike about three times now. Good seller and generally reasonably priced. Not familiar enough with the CS-1 market though to know if this is a decent price or not. Wish the nickel 12 they have listed was a round butt since I've been looking for a 2", nickel, rb.
