Holosun HE407K-GR X2 6 MOA Green Dot Reflex Sight

Holosun HE407K-GR X2 6 MOA Green Dot Reflex Sight is an open reflex pistol optic designed for subcompact and concealed-carry handguns. It provides a single 6 MOA green dot reticle in a compact, non-magnified 1x sight, optimized for rapid target acquisition at close defensive distances.

Built by Holosun, the HE407K-GR X2 is intended for short-range pistol platforms where size, durability, and simplicity are priorities. The larger 6 MOA green dot supports fast visual pickup under stress, while the lightweight housing and low-profile design make it well suited for everyday carry, backup pistols, and compact range guns. Electronic features are focused on reliability and battery efficiency rather than complexity.

Specifications & Construction

The HE407K-GR X2 uses a CNC-machined 7075 aluminum housing with a black anodized finish for strength and corrosion resistance. It operates at 1x magnification and uses multi-coated optics with an approximate window size of 0.58″ × 0.77″. Listed weight is approximately 4.37 oz, with an overall length of about 2.44 inches. Windage and elevation are mechanically adjustable in 1 MOA increments. Power is supplied by a side-loaded battery system designed for extended runtime, with some source data indicating up to approximately 50,000 hours depending on brightness settings.

Compatibility & Intended Use

This optic uses Holosun’s K-series footprint and is designed for compact pistol slides. It is commonly paired with subcompact platforms such as the SIG Sauer P365X/XL family, though fitment may vary depending on slide cut and mounting interface. Some pistols may require an adapter plate depending on boss pattern or footprint configuration. Typical applications include concealed-carry pistols, EDC handguns, compact service pistols, and range pistols where a simple, fast green-dot sight is preferred.
