Our opinion on this sight

The Shogun team is impressed by how compact this sight is without compromising on functionality. The 10 brightness settings make it usable in all lighting conditions, from dusk to bright daylight. Its low profile makes it ideal for those seeking a discreet setup.

Technology and optical performance

The 3 MOA red dot is precise enough for accurate aiming without obstructing the target. With a magnification of 1x, you retain full peripheral vision – essential for dynamic use. The fully multi-coated lens prevents reflections and fogging, while the 6061 aluminium housing ensures excellent durability.

The CR2032 battery provides up to 40,000 hours of use at average brightness. The battery is cleverly mounted on the underside, so you do not need to remove the sight for replacement.

Mounting and compatibility

This red dot sight uses the RMSc footprint and is compatible with Picatinny and Weaver rails – the standard for airsoft replicas and many PCP air rifles. This versatility means you can mount the sight on virtually any platform with the correct adapter plate. The compact design eliminates overhang on smaller slides.

Who is this sight intended for?

This sight is suitable for air rifles, suitable for airsoft, and suitable for firearms, making it a versatile choice for various disciplines.
