Holosun HE515CT-GR 1x20mm Green Dot/Circle Multi Reticle Sight - Black

The Holosun HE515CT-GR is a compact 1x20mm green dot sight built for shooters who demand flexibility without the bulk. This micro reflex optic delivers Holosun's multi-reticle innovation in a titanium package that works equally well on rifle platforms, shotguns, or pistol slides—anywhere you need a speed sight that doesn't compromise on precision.

The standout feature is the button-controlled multi-reticle system. Flip between a razor-sharp 2 MOA dot for deliberate shots and a rapid-acquisition 65 MOA circle dot when you're moving or engaging at varied distances. Both reticles glow in green, an advantage many shooters appreciate for low-light visibility and reduced eye fatigue compared to red optics. The green illumination cuts through environmental glint and delivers excellent contrast from dawn through dusk.

Battery logistics are refreshingly simple. A single CR2032 lasts up to 5 years of continuous use, and Shake Awake technology powers the sight down when you're static, firing it back up and recalling your last reticle choice with motion—no reset required. Holosun's solar fail-safe system means the reticle stays active in daylight even if the battery is dead, giving you a genuine backup out in the field. The titanium housing is CNC machined for hard use, and the removable flip-up lens covers integrate kill flash to stop glint. This is a sight engineered to go the distance with minimal fuss.

Frequently Asked Questions

What weapons can I mount the HE515CT-GR on?

This is a platform-agnostic micro sight, meaning it works on rifles, shotguns, and pistols with standard optic mounting solutions. The 20mm footprint is compact and lightweight enough for any application that accepts micro red dot mounts.

Can I use this sight without a battery?

Yes. Holosun's solar fail-safe technology keeps the reticle illuminated in daylight conditions even if the battery is dead or missing. In low-light or indoor environments, you'll need the CR2032 battery installed for the green illumination to function.

What's the difference between the two reticles on the HE515CT-GR?

The 2 MOA dot is ideal for precision shooting and target work, allowing fine aim at distance. The 65 MOA circle dot is optimized for faster target acquisition and works better when you're moving or engaging multiple targets. A single button press switches between them instantly.

How long does the CR2032 battery actually last?

Holosun rates the battery for up to 5 years of continuous use. The Shake Awake technology extends real-world battery life by putting the optic to sleep when stationary, so your battery will likely last even longer if you're not using the sight every single day.
