The clicks
of the front and rear sight are calibrated for 1 MOA (3 cm
at 100 m), allowing for a wide vertical and horizontal range
of adjustment (240 cm at 100 m) and easy sighting-in
of the scope. These sights require no batteries and thus
are always ready for use. Corrosion-resistant Mil-spec
materials and raised sides protecting the ghost ring and
front sight from impact damage ensure many years of
trouble-free service.
