$518.70
Available on back-order
The Holosun HE407K-GR X2 is a compact open reflex sight designed for subcompact and micro-compact pistols such as the SIG P365 series and other slim optics-ready slides. It projects a single 6 MOA green dot from a 540nm Super LED, which gives fast pick-up and strong contrast in bright daylight, and runs for up to 50,000 hours on a side-loading CR1632 battery. The X2 generation adds Lock Mode so buttons cannot be bumped off your chosen setting, and Shake Awake wakes the sight the moment the pistol moves. The 7075-T6 aluminium housing uses Holosun’s K footprint; an adapter plate is needed for slides with other cuts.
What is the difference between the HE407K-GR X2 and the HS407K X2? They are the same sight; the GR version uses a 540nm green 6 MOA dot and the HS407K X2 uses a red 6 MOA dot.
Does the HE407K-GR X2 have Solar Failsafe or a selectable reticle? No. Holosun lists it with no solar panel and a fixed 6 MOA dot; the 507K X2 is the Multi-Reticle version.
What footprint does it use? The Holosun K footprint, shared with the 507K. Slides with a four-boss RMR interface need an adapter plate.
