Nikon Action 8x40 Brochure page 18

If precision is the name of the game,
the name of the riflescope is Monarch X.
Designed from the ground up with the
professional in mind, Nikon Monarch X
scopes are overbuilt with 30mm tubes
and glass etched reticles for extreme
ruggedness and optical excellence.
These scopes perform at the top of their
game for tens of thousands of rounds,
and will always be ready.
