I picked up a tidy ex demo MTC Viper 8-32x60 at the Midland Game Fair recently and as many of you will know, it comes with a 6 in sidewheel. So far, I've mounted the scope on a TX200 Mk3 and an HW97k and the sidewheel fouls the stock on both rifles. The scope has been set up properly in the mounts using spirit levels and plumb line, so I know its not on the squint. Is this a well known issue, or is it me !!!
