He403r-gd

The Holosun HE403R-GD is a 20mm micro red dot sight engineered for modern rifle and carbine platforms where real estate and weight are critical. This compact optical sight is purpose-built for tactical professionals, competitive shooters, and law enforcement operators who demand reliable target acquisition without compromising handling characteristics. The HE403R-GD delivers the durability and optical performance expected from Holosun's proven track record in demanding field conditions—from urban patrol to high-round-count training scenarios.

At the core of this sight is Holosun's Gold Super LED technology, rated for up to 100,000 hours of continuous operation—translating to over 11 years of uninterrupted runtime. The rotary brightness adjustment dial provides 12 distinct settings, allowing operators to dial in optimal reticle intensity across variable lighting conditions without fumbling through menus. The 2 MOA red dot reticle strikes the balance between precision aiming and rapid target engagement; tight enough for precision work at distance, yet visible enough for close-quarters identification. Weighing just 1 pound, this sight maintains a low center of gravity and preserves the natural ergonomics of your platform.

Operators running AR-15s, carbines, and modern sporting rifles benefit most from the HE403R-GD's compact form factor and shake-awake capability, which conserves battery life during storage and extended field operations. Its micro footprint integrates seamlessly onto standard Picatinny rails, eliminating the need for custom mounts or adapter plates. Whether mounted on a rifle upper receiver or co-witnessed with iron sights, this sight delivers the reliability and optical clarity that professionals expect when lives or competition outcomes depend on first-round accuracy. The HE403R-GD represents proven technology backed by thousands of duty hours across law enforcement and military end users.
