This riflescope assembled in the metal strong housing, has weight 560 g ONLY, but at the expense of a lens executed on technologies of high contrast (see information about Dedal-490), rather big optical magnification (3.7х) and installed Gen.III tube, riflescope provides distance of night shooting to 450 m in moonless dark night.
You can install various IR-illuminators with their own independent power supply at this riflescope. Additional IR installs on Weaver/Picatini standard rail.
The mount for the weapon is delivered, as a rule, without rigid mounting to the sight housing, that allows to realize special adaptation of the device to concrete model of the gun.
