I have both the fusion and the xs60c. fusion in 177 and xs60c in 22They are basically the same rifle in feel and look. the composite stock of the fusion is very solid and probably weighs slightly more than the wood one on the xs60cthey both are accurate with the fusion being much quieter from the factory.my fusion puts out the most fpe with 13.43g 177 cal pellets for about 10 fpe. they are also the most accurate in mine.If you need quiet and dont want to make the xs60c 5 or 6" longer, get the fusion. If sound level is not a factor ... coin toss as both are nice rifles in my book
You know what's odd I asked Mike for a power tuned .22 cal xs60c and the best it will do is 635 to 640 fps. Wonder if mine is maxed out or not?
