Holosun HE407K-GR X2 6 MOA Green Dot Reflex Sight

Holosun HE407K-GR X2 6 MOA Green Dot Reflex Sight is an open reflex optical sight designed for subcompact and concealed-carry pistols. It provides a single 6 MOA green dot reticle for fast target acquisition while maintaining unlimited eye relief.

This sight is intended for short-range pistol platforms where a compact, durable non-magnified optic is required. Primary applications include concealed-carry pistols, everyday-carry (EDC) setups, and compact service or backup pistols used on the range or in defensive contexts.

• 6 MOA crisp green dot reticle for quick aiming.
• Shake Awake technology powers the optic on with motion to conserve battery life.
• Lock Mode prevents inadvertent changes to brightness/buttons; buttons redesigned lower and out of the way.
• Durable 7075 aluminum housing with black anodized finish.
• Side-mounted battery tray for accessible battery changes without removing the optic from the slide.
• Multi-coated lenses with parallax-free design and unlimited eye relief.
• 1x magnification with 12 brightness settings, including night-vision compatible levels.
• Adjustment increments of 1 MOA for windage and elevation.

Compatibility & Intended Use

The HE407K-GR X2 is designed for compact pistol slides and is commonly paired with subcompact platforms. The product is described as using Holosun’s K footprint and is referenced as a direct fit for the SIG Sauer P365X/XL family; some slides with four-boss interfaces may require an adapter plate. The optic footprint is also listed as Shield/RMS-C in some specifications—fitment varies by slide and mount choice. Mounting hardware may be required depending on slide pattern; a low mount is referenced in some source data while other listings indicate a mount is not included.

Typical setups: compact carry pistols with a slide cut for micro reflex optics, concealed-carry/EDC pistols, and compact range pistols using a primary reflex optic with optional co-witness or backup iron sights.
