Aim-O Holo Sight 551 Red/Green Illumination

One of the most popular types of red dot sight, the holo sight 551 is featured on so many films and TV shows that it’s hard not to recognise it. The Aim-O version is full metal construction and has adjustable brightness as well as being able to swap between a red and green reticle.

They take 4x LR44 batteries in the main compartment and the adjustment buttons are situated on the rear making them easily accessible at any point out in the field. To switch the sight off, simply press both brightness adjustment buttons at the same time and it will switch off.
