Quite a few rifles suffer this problem. Supplied with open sights the stock is lower so your eye is level with the sights. As soon as you add a scope your cheek comes off the stock. It's not so much of a problem with rifles that have a high check piece ready for a sight system ie a scope, that is higher than open sights. Not so bad with small scopes. My first powder rifle had open sights but fitted with low mounts, 40mm scope with a 1" tube. I updated to a 50mm a/o 1" with med / high mounts then s/f 30mm tubes, annoyed with my head floating above the stock. After trying temp' stock padding solutions I'm down sizing my scope to use low mounts getting my cheek back on the stock. Sometimes problems become hidden because you have just spent silly money & your brain refuses to see what the problem is & you waste money / time going the wrong direction for a cure.
