The Holosun HE403B-GR Elite is a compact green dot sight built for shooters who demand speed and durability without unnecessary bulk. This 1x magnification optic pairs Holosun's proven LED technology with a crisp 2 MOA dot, making it equally at home on a tactical rifle, shotgun, or pistol. The green reticle cuts through harsh daylight and performs dependably in low-light conditions—a real advantage over traditional red dots for some eyes. Weighing in as a micro red dot, it mounts to standard Picatinny rails and arrives in Flat Dark Earth, a finish that blends with modern rifle platforms and won't catch light.
What sets the 403B apart is Holosun's Shake Awake technology: the sight powers on automatically with movement, so you're never caught with a dead optic when you need it. That matters in the field. Battery life stretches to five years on a single CR2032 cell under normal use—a massive practical advantage for hunters and shooters who don't obsess over constant battery checks. The sight is parallax-free, meaning point of aim stays true even if your head position shifts slightly, and it's engineered to handle the temperature swings and weather abuse that come with serious field use.
Whether you're building a modern sporting rifle, setting up a defensive shotgun, or running a rapid-fire training rig, the 403B-GR delivers the speed of a red dot with the color advantage some shooters prefer. It's the kind of optic that disappears into the gun—reliable, rugged, and ready.

| Optic Type | Micro red dot (LED) |

The HE403B-GR works with shotguns, rifles, pistols, air rifles, and crossbows—any platform with standard Picatinny rails or compatible mounts. The compact footprint makes it ideal for defensive setups, hunting rigs, and sport shooters.
A single CR2032 battery can power the sight for up to five years under normal use. Combined with Shake Awake auto-shutdown when the sight is motionless, you'll rarely think about batteries. Standard CR2032 cells are inexpensive and available everywhere.
The green reticle is easier for some shooters to pick up in bright daylight and certain lighting conditions. While red dots remain popular, green dots offer a contrast advantage that many hunters and sport shooters prefer. Personal preference and your eyesight both play a role—if you've struggled with red dots, green is worth trying.
The product ships with the sight and Picatinny-style mounts. Refer to Holosun's documentation for a complete packing list and any mounting hardware details.
