I think a £1000 price tag would not sell many new spring rifles. I would suspect that £5-600 would be the high water mark for the price. This equates roughly to the price of an existing top end springer plus the cost of a V Glide. Fancy expensive stocks should always be priced as extras but certainly a decent walnut stock should be standard. The 'enthusiast' market is not really a guide to whether a high end factory-standard springer would find favour with more shooters. I suspect it wouldn't.
