Things I liked:I've mounted this scope on my RWS model 54. After months of reading reviews I made the decision and have found it to be an excellent scope. The price, quality, robustness and accuracy is awesome! At 50 yards, I'm placing a .177 pellet group within the size of a quarter! Things I would have changed:Nothing. What others should know:Configure this scope with a high rise mount to clear the end of the scope from touching the barrel.
