Personally, I find that ventilated recoil pads on air rifles are a joke, and have done for ever since they started fitting them. I think the first one I saw was on a BSA Airsporter S I bought. I don't mind the Weihrauch rubber butt pad but a ventilated recoil pad is ridiculous. My first air rifle was a BSA Meteor Mk2 which had a 'grooved' beechwood' stock and so did had the Airsporters at the time, but with plain walnut stocks.
