Special Features
- The Grade 5 titanium housing delivers more than double the tensile strength and five times the fatigue strength of 7075 aluminum, giving you a housing that resists deformation, cracking, and impact damage under the hardest duty and competition use without adding weight over aluminum designs.
- Grade 5 titanium also resists saltwater corrosion, making the HE508T-RD-X2 a functional option for maritime environments, coastal carry, and wet-weather field use where aluminum housings would require additional protective treatment over time.
- The Multi-Reticle System lets you toggle between 2 MOA dot only for precision shooting, 32 MOA ring only for fast close-range acquisition, or the full circle-dot combination for a versatile aiming solution that covers both scenarios from a single optic.
- Solar Failsafe uses an integrated solar panel as both a light sensor for auto brightness and a secondary power source, keeping the reticle fully functional in any lit environment even after the CR1632 battery reaches complete depletion.
- The lockout mode disables the brightness adjustment buttons during carry and storage, preventing accidental intensity changes from holster pressure, gear contact, or handling during transport between uses.
- The side-load CR1632 battery tray allows a complete battery swap without removing the sight from the slide, keeping your mount torque and established zero intact and eliminating any need to re-zero after routine battery maintenance.
Practical Benefits
- The RMR footprint fits any slide milled for a Trijicon RMR, covering factory MOS pistols, aftermarket milled slides, and adapter plate systems on Glock, Sig Sauer, Smith and Wesson, CZ, Walther, and other widely carried full-size and compact platforms.
- The 0.63 x 0.91 inch window delivers a wide, unobstructed sight picture that makes the 2 MOA dot fast to find on a rapid draw and lets you track the target and front sight together without the window cutting off your view during aggressive presentations.
- The auto brightness mode uses the solar panel as a continuous ambient light sensor to adjust reticle intensity automatically as lighting conditions change, so the dot never washes out in direct sunlight or blinds you when you move indoors.
- The 2 night vision compatible brightness positions make the HE508T-RD-X2 a functional option for shooters who run suppressed duty pistols, pair their handgun with night vision devices, or train in low-light defensive scenarios.
- Your HE508T-RD-X2 gives you a titanium-housed, solar-backed, multi-reticle red dot on a full-size or compact duty pistol that holds zero through hard use, resists corrosion in wet environments, and carries the Holosun Elite warranty behind every round you put downrange.
The Holosun 508T Elite Red Dot Sight (HE508T-RD-X2) with its Grade 5 titanium housing, 32 MOA ring, and 2 MOA red dot is a capable tool for duty shooters, competitive pistol athletes, and serious defensive carry users who demand the toughest open reflex sight Holosun builds on the most universally supported pistol footprint available.
