Passing on a good deal. For 30$ (Amazon)I was sceptical but the reviews were good. It arrived and I have to say those were 30$ well spent.
All I can say is that if it can handle being on an RX2 25 cal then that is harsher more punishing on scopes than a springer. I have one on a Beeman R7 which is very low power and mild recoil. YO!
