Have they fixed the galling issues on the R7 or HW50s?
... I would rather spend a little time figuring out how to adjust the cocking arm properly then using a band aid like a plastic insert.
I have a HW30 and never have had a galling issue. I have a HW35, also with a two piece cocking arm, with no galling. The worste galling I have seen was with a RWS350 with a two piece cocking arm. My limited experience is that the galling issue is more do to the 2 piece cocking arm the any paticular brand. HW just happens to sell a lot of rifles. Since the rifles were designed not to gall I would rather spend a little time figuring out how to adjust the cocking arm properly then using a band aid like a plastic insert.
