DN Adapters utilize parts made of various metals. Machined body of the adapter is made of light alloy and offers high durability and low weight. Screws, spring, fixing clamp and pins are steel.
You do not need special tools (such as torque wrench) to install the adapter on the objective lens of a day device. All mounting operations can be made only with the help of the included wrenches.
In order to mount the adapter on an objective lens of a day device (spotting scope, binoculars or sight), you should use one of the adapter rings supplied in the box. The rings are made of plastic which prevents damage of the objective lens and guarantees dense and even contact between the lens and the adapter.
The adapter is secured by fastening the fixing clamp. Operating run of the clamp lies in the horizontal plane (parallel to the optical axis of a day sight and attachment), which prevents the adapter from spinning on final fixing after positioning adjustment. Design of the adapter allows you to set the clamp either on the right or on the left side.
The adapter features long life, also when used on daylight optical sights mounted on high caliber fire arms. Advanced operational qualities imply that adapters can be used at a temperature range, wider than that of the Forward DFA; wear resistance and general durability of particular parts of the unit.
