The Holosun HE503R-GD is an enclosed reflex sight featuring quick brightness adjustment via a side-mounted rotary knob. The model features a gold LED that provides high reticle contrast in various lighting conditions and improves visibility for users with color vision deficiencies. Parallax is minimized and virtually imperceptible during use.

MRS system for versatility in different situations

The sight uses the MRS system, allowing the user to choose between two reticles without the need to re-zero. The 2 MOA dot is suitable for precise aiming at longer distances, while the 65 MOA circle with a 2 MOA dot is ideal for rapid target acquisition in dynamic shooting.

The LED displays a gold reticle and offers 12 brightness settings. 10 settings are intended for daylight use, while 2 settings provide compatibility with night vision devices. The mechanical rotary knob allows quick and intuitive brightness adjustment.

Durable construction and two mounting heights

The aluminum housing provides low weight while maintaining high mechanical durability. The sight meets the IP67 protection standard, providing dust resistance and protection against temporary immersion in water. The sight can be mounted on a Picatinny rail at two different heights – Low and Lower 1/3 Co-Witness – and can be used with magnifiers such as the Holosun HM3X and HM6X.

Precise adjustment and FMC optics

The 20 mm lenses feature FMC coatings that minimize reflections and increase light transmission. The aiming point can be adjusted within a +/- 50 MOA range in both axes, with a click value of 1/2 MOA. The sight is powered by a single CR2032 battery, which, thanks to the energy-efficient LED, provides up to 50,000 hours of operation.
