Yes. I own a stif-stik, a stealth and a classic stiffi. I love the stif-stik with the money pattern. They are the quietest barrels I have seen, or heard, and dead on balls accurate at each bore I have tried. I love the stepped bore, the price is high but hey CF is stronger that steel. While they look sexy as could be, they are tough as nails also.
I have heard the claim that they are loud. Absolutely no way. The lucky 15 is heralded as one of the quietest around and I have shot both side by side and on same marker before.
