FX Airguns Crown MK2 .22 Air Rifles

I purchased this gun only four weeks ago and managed just one outing with it. It is my first 22 and I am not sure that I like it as much as my other guns which are all 177 calibra so have decided to sell this one and get the same model in a 177. Only shot around 90 pellets in my garden. Unmarked, comes in an FX case with two cartridges and a silencer. Would consider an exchange for a 177. Cost £1360 less than a month ago.
