Things I liked: It fits! It works very well!
Things I would have changed: nothing.
Things I liked: Dissapointed
Things I would have changed: My Mendosa RM1000 22 must not be standard. The 11mm notch on top of the chamber is shorter than the scope mount. I carved the mount to allow it to fit. The hight is enough to let the repeater function of the air rifle to work with a 40 mm objective lense. Instructions would be nice!
