Full description


The Theta Optics Compact 2.5-10x40 Scope is a relatively compact Telescopic Sight which offers a variable zoom, selectable via a dial at the rear from 2.5x magnification to 10x. It comes out of the box with an integrated 20mm Mount so you will be able to take it out the box and mount it straight onto your Airsoft Gun. The scope has an illuminated reticule which can be activated once you install the included CR2032 Battery underneath the Illumination Control Dial. This dial then gives you the option of Red/Green crosshair and five levels of brightness, making it suitable for indoors, outdoors, dark and light environments. At the rear of the sight is a focus dial to adjust the sharpness of the sight picture, which will require different settings depending on the user. The point of impact can be adjusted by making use of the tool-less turrets on the top and side of the unit, allowing you to align the scope with any Airsoft Gun (provided there isn't a fault with your gun!).

Really nice build quality.
Clear sight picture with all the adjustments you need.
The quick release/fit mount is probably my favourite feature.
