Earlier, I said that 1inch scopes have 2mm walls, like the 30mm scopes. I have since found out that this is not the case. The 1inch tube walls are closer to 1.2mm thick. (We always thought the 30mm tubes were stronger than the 1inch tubes because of the larger diameter. It would appear that it's mainly because the walls are thicker.) Also, it is possible to have a large range of adjustments in a 34mm tube with 4mm thick walls by reducing the focal length of the objective. Age is a terrible thing; I knew that last one and forgot. As an added bonus, a shorter scope body will be tougher than a longer scope body with the same wall thickness. I am not aware of any riflescope with walls thicker than 4mm at the moment. So look at the 34, 35, 36 and 40mm for the maximum in toughness and look for the shortest one as the king in that department.
