Holosun HE515CT Titanium Enclosed Rifle Sight
Key Features
- Grade 5 Titanium Housing – more than double the tensile strength and five times the fatigue strength of 7075 aluminum, rated for hard-use rifle and carbine duty.
- Multi-Reticle System (MRS) – switch between a 2 MOA dot, a 65 MOA circle, or the combined circle-dot for precision or rapid close-range work.
- Solar Failsafe – an integrated solar panel supplements battery power and keeps the optic running on ambient light if the battery ever fails.
- Automatic & Manual Brightness – 12 settings (10 daylight + 2 night-vision compatible) with a self-adjusting auto mode and full manual override.
- Shake Awake Technology – motion activates the reticle instantly and powers down during inactivity to preserve battery life.
- Up to 50,000-Hour Battery – a single side-loading CR2032 runs for years; the tray swaps without removing the optic from the rifle.
- QD Absolute Co-Witness Mount – included quick-detach mount sits at 1.41″ for proper alignment with AR-height iron sights.
- IP68 Sealed & 1000G Shock Rated – fully waterproof, dustproof, and built to survive heavy recoil and rough handling.
Description
The Holosun HE515CT is a 20mm enclosed micro reflex sight engineered for shooters who demand the strongest, most reliable platform Holosun builds. Its Grade 5 titanium housing shrugs off impacts, recoil, and even saltwater exposure, while the Multi-Reticle System lets you tailor the aiming point to the task – a fine 2 MOA dot for precision, a 65 MOA circle for fast target acquisition, or both together.
Solar Failsafe and Shake Awake keep the optic powered and ready around the clock, and the side-loading CR2032 tray makes battery changes effortless. Shipping with a QD absolute co-witness mount and removable lens caps, the HE515CT mounts to any Picatinny rail and is ready for duty, competition, or hard-use range time straight out of the box.
