I have had both a RWS 350 and still own a HW80K /.22 The German quality speaks for it's self. Kills skunks ,pigeons,crows and grouse no problem.Anything under 25lbs.To smooth out springers a lube tune in recommended along with polishing the internals to remove machining marks.New seals are also need as new from the factory many are damaged or dry.I put in a Macarri mainspring /guide in a RWS 34 and a V/mach kit in the HW80.the HW80 will penetrate 3/4" fence boards at 30 + yards.The Sportsmatch one piece mt is best and the UTG Leaper's mt for the RWS guns+Weaver rings
