Holosun
The Holosun HS403R micro red dot sight delivers fast target acquisition and reliable performance in a compact, lightweight package built for shooters who demand simplicity without compromise. This 1x non-magnified optic pairs a crisp 2 MOA dot with a Rheo Stat dial for brightness adjustment, making it equally at home on a rifle, shotgun, or pistol platform. Holosun's track record since 2013 emphasizes practical innovation—cutting through the noise to deliver glass that simply works when it matters.
The HS403R's micro footprint keeps sight height low and profile minimal, ideal for shooters running modern Picatinny platforms or co-witnessing with iron sights. The side battery tray design keeps the top of the optic clean and uncluttered, while the Rheo Stat dial lets you dial in the perfect brightness for your lighting conditions without fumbling through menus. Whether you're running a defensive rifle, hunting rifle, or sport carbine, this sight gets out of your way and lets you focus on the shot.
Built in matte black, the HS403R resists glint and blends seamlessly with modern tactical and hunting setups. If you want a proven micro red dot that handles the work without unnecessary features or complexity, this is a serious contender.
| Magnification | 1x |
| Reticle | 2 MOA Dot |
| Mount Style | Picatinny-Style |
| Brightness Adjustment | Rheo Stat Dial |
| Battery Location | Side Tray |
| Finish | Matte Black |
| Optic Type | Micro Red Dot |
The HS403R mounts to any firearm with a Picatinny rail. It's commonly used on AR-15 rifles, AK platforms with Picatinny mounts, shotguns, and pistols with mounting plates. The compact size makes it ideal for co-witnessing with backup iron sights.
MOA (Minute of Angle) describes the reticle size. A 2 MOA dot is versatile—small enough for precision at distance but large enough for quick target acquisition at close range. It's a solid middle ground for hunting, sport shooting, and defensive applications.
The Rheo Stat dial lets you adjust the dot brightness to match ambient light conditions. Simply rotate the dial to increase or decrease brightness without removing the sight or accessing a battery compartment.
