Full description


Constructed from Aluminium, this Sight is tough and solid. It is easily installed onto Airsoft Guns with a 20mm Rail, via the Integrated Mount that is installed on the Sight out of the box. Simply loosen the nut on the Mount and place it over your Rail System, tightening the nut up again to secure the Sight in place. The Red Dot is powered by a CR1620 Battery (included), which is to be installed inside the Illumination Control Dial. Just unscrew the cover to access. The Sight has a set of front and rear Flip Up Lens Covers which will protect the lenses during transport and storage, and can be left on the Sight long-term rather than removed completely, as they flip up and out of the way when not in use.

The Target Dot is fully adjustable so that you can align your BB impacts with the aim-point in the Sight. To make adjustments, you need to unscrew the protective Turret Caps and use a Flat-Head Screwdriver to adjust the point of impact. Included in the box is an Instruction Manual, Cleaning Cloth, CR1620 Battery, Flip-Up Lens Covers and the Sight itself. If you're looking for a simple and solid Red Dot Sight for your Airsoft Gun, then the Theta Optics Red Dot Reflex Sight is ideal.
