"...rifles were taken off the standard..." Hi. Some barrels were further tested for quality(Star barrels), but there was no special 'sniper' trigger guard. The bolt handle was cut so it would clear the scope, not bent.
A scope caring case is kind of daft. Scopes were not removed by the user like in Saving Private Ryan. Take the scope off and you have to sight in again. The 2 screws on the back of the base was how the windage was adjusted. Isn't something doable in the field.
