The Outback II is one of the top three .22 suppressors on the market and an excellent choice. I tired one on my Ruger MKII and the dominant sound was the action noise. I know that Jensen Arms in Loveland has the Outback II in stock.

I personally would get an SWR Warlock because it is a little quieter (3.1dB) and SWR's excellent customer service. However the down side to the Warlock is that it is more expensive, about $50, and I can not think of a dealer in CO that stocks SWR so you would have to have them order it.
