I did the same thing as randal. I have been jonseing for a day state air ranger for 2 years. I picked one up from long island with a hugget shroud (term for suppressor for air rifles). It is very quiet. Again, extremely accurate out to about 100 yds if you do your part. I have 60-70 yd max in my back yard for squirrel, chipmunk, and rat control. I will dial this in and go to town this spring.
Just spend an hour or so watching teds videos.
