Holosun HE509T-RD X2: Rugged Closed Red Dot Sight for Pistol Mastery

The Holosun HE509T-RD X2 is a professional-grade, fully enclosed red dot sight designed for shooters who demand uncompromising resilience, rapid target acquisition, and advanced adaptability on their handguns. Crafted for both duty and competition, this optic stands out with its robust titanium housing, crisp red reticle, and a suite of Holosun’s most trusted technologies—offering a unique blend of reliability and user-driven control.

What Makes the HE509T-RD X2 Different?

• Titanium Enclosure for Extreme Durability:
  The body is machined from Grade 5 titanium, giving it exceptional resistance to impact, corrosion, and daily wear. IP67 waterproofing and nitrogen purging ensure the optic performs in rain, snow, and dusty conditions.

• True Enclosed Emitter:
  Unlike open reflex sights, the HE509T-RD X2’s sealed design keeps the LED protected from water, dirt, sweat, and carbon—delivering a consistently clear 2 MOA red dot or 32 MOA circle reticle in any environment.

• Multi-Reticle System (MRS):
  Instantly switch between a fine 2 MOA dot, a bold 32 MOA circle, or a combined reticle. This flexibility supports both pinpoint accuracy and lightning-fast target transitions—no need to re-zero.

• Solar Failsafe™ and Shake Awake™:
  The integrated solar panel automatically powers the optic in bright conditions, providing a backup if the battery runs low. Shake Awake puts the sight to sleep when idle and instantly reactivates with motion, maximizing battery life and readiness.

• Red Super LED & Optical Clarity:
  The 650nm red LED is optimized for high visibility in all lighting, with a multi-coated, distortion-free lens for a crisp sight picture. Up to 50,000 hours of runtime on a single CR1632 battery means you can focus on your training or duty—not your power supply.

• Lock Mode for Tactical Security:
  Prevents accidental changes to brightness or reticle settings during high-stress scenarios—ideal for concealed carry or duty use.

• Mounting Versatility:
  Supplied with an RMR-compatible adapter plate, the HE509T-RD X2 is ready for direct installation on a wide range of optics-ready pistols.
