Sig Romeo 7
The Sig Romeo 7 stands out with its low dispersion (LD) glass. This particular type of glass is designed to function optimally with less light, making it capable of providing brighter, more vivid images.
Its image processing is superior compared to regular glass, ensuring color accuracy and precise readings under varying lighting conditions.
The lenses are fully multi-coated, enhancing its durability as it is scratch and waterproof. The glass-etched reticle ensures a stable view that remains unaffected by recoil or accidental drops.
Aimpoint Pro
Aimpoint Pro utilizes fully multi-coated lenses, ensuring that the images remain clear and sharp. The housing of the sight is nitrogen purged to prevent moisture from fogging the sight from the inside.
Even though it does not use LD glass like the Sig Romeo 7, its performance under different lighting conditions, be it sunlight or low light, is impressive.
It also supports night vision devices (NVDs), providing versatility for a range of shooting conditions.
