They are used for hunting and shooting as well as for military and police applications.

This device is a precision optical instrument that deserves reasonably cautious care. The following tips are provided to ensure long lasting use of the sight.

When cleaning the lenses with a microfibre cloth or soft, wet cloth, blow away the dust on surface first. Remove finger prints or other oil with lens cleaner, a soft cloth or microfibre cloth. No special maintenance is needed for the housing surface.

Avoid touching the glass surface with dry cloth or tissue paper. Do not use organic solvents such as alcohol or acetone. Do not try to dismantle the device as the internal parts are specially cleaned and sealed with an anti-fog treatment. Therefore the red dot sight has a nitrogen filling you would inevitably destroy by dismantling it. Any such attempt will avoid the warranty. If repair is needed, you can call our customer service centre or send us an email.
