Purchased SilentCat for Dad on Father's day. Had Red Squirrels w/ bad habits chewing the deck & wiring cables outside. At first, we were using .22 CB rimfires in a Polish WZ48 trainer -- a very silent/accurate close-range set-up. Bought the Gamo so not worry neighbors thinking we were out using a centerfire and hoping to be even quieter. #1 The Silent Cat is not all that quiet! I wager a model in .22 going slower would be. FiberOptic sights are excellent. Scope is fine - but keep in mind... good grouping is never gonna happen w/ it mounted to receiver on a break action barrel. Function, workmanship, velocity, & penetration are superb.
