Holosun HE507K-GR X2 Green Dot Reflex Sight 2 MOA/32 MOA Circle

The Holosun HE507K-GR X2 delivers precision green dot technology in an ultra-compact package designed for subcompact pistols and backup applications. This advanced reflex sight combines Holosun's Solar Failsafe technology with versatile reticle options to maintain target acquisition in any lighting condition.

What Makes This Different

The HE507K-GR X2 stands apart with its green 525nm laser diode that provides superior visibility in bright daylight compared to traditional red dot sights. Solar Failsafe technology automatically switches between battery and solar power, extending operational life beyond 50,000 hours on a single CR1632 battery. The multi-reticle system allows instant switching between 2 MOA dot, 32 MOA circle, or combined reticle configurations without tools.

Key Features

• Green 525nm laser diode with 12 brightness settings plus auto mode
• Solar Failsafe technology with 50,000+ hour battery life
• Multi-reticle system: 2 MOA dot, 32 MOA circle, or dot/circle combination
• Ultra-compact 0.58" x 0.77" footprint for subcompact pistols
• 6061-T6 aluminum housing with black anodized finish
• Direct mount compatible with RMSc footprint
• Shake Awake technology activates sight with motion detection

Field performance remains consistent across temperature extremes from -4°F to 140°F, making this sight suitable for duty carry, competitive shooting, and personal defense applications. The green dot wavelength cuts through atmospheric haze and bright backgrounds more effectively than red alternatives. IPX8 waterproof rating ensures reliable function in adverse weather conditions, while the titanium housing withstands repeated slide cycling without zero shift.
