Six things the 407C X2 does
-
Lock Mode
Hold the buttons to lock them. Once locked, a bump in the holster cannot change your brightness — new to the 407C line with the X2.
-
Solar Failsafe
A top-mounted solar panel keeps the dot running if the battery fails, and in Auto mode it sets brightness from the light it senses.
-
Shake Awake
A motion sensor shuts the LED off after 10 minutes of stillness (adjustable to 12 hours) and wakes it the instant the pistol moves.
-
Green Super LED
A 540 nm green dot, the wavelength the eye is most sensitive to, with up to 50,000 hours of battery life on setting 6.
-
Side battery tray
The CR1632 loads from a side tray, so you change the battery without unmounting the optic or losing your zero.
-
Parallax-free glass
Multi-coated reflective glass, parallax-free with unlimited eye relief, in a 0.63″ × 0.91″ window.

Holosun 407C questions, answered
What is the Holosun HE407C-GR X2?
The HE407C-GR X2 is Holosun’s open-reflex pistol red dot with a green 2 MOA dot. It runs on a side-loading CR1632 battery backed by a solar panel, weighs 1.5 oz, and adds Lock Mode to the 407C line so the buttons cannot be pressed by accident.
What footprint does the Holosun 407C use?
The 407C X2 uses the industry-standard RMR-pattern footprint, so it fits slides and adapter plates cut for the Trijicon RMR pattern.
How long does the HE407C-GR X2 battery last?
Holosun rates it at up to 50,000 hours on brightness setting 6 from a single CR1632. The battery loads from a side tray, so you do not have to remove the optic to change it.
What is Solar Failsafe?
A solar panel on top of the housing powers the dot when light is available. If the battery dies, the sight keeps running in daylight; in Auto mode it also sets dot brightness from the ambient light it senses.
What is Lock Mode?
Lock Mode disables the brightness buttons so a bump in a holster cannot change your setting. It was introduced on Holosun’s 2018 LEM pistol optics and is new to the 407C line with the X2.
What does Shake Awake do?
A motion sensor turns the dot off after a period without movement — 10 minutes by default, adjustable up to 12 hours — and turns it back on the instant the pistol moves. It can also be disabled.
Green dot or red dot?
The green LED sits at 540 nm, the part of the spectrum the human eye is most sensitive to, so many shooters find it easier to pick up, especially in bright light and for red-green color deficiency. The same optic with a red dot is the HS407C X2.
Is the 407C night-vision compatible?
Yes. Of its 12 brightness settings, 10 are daylight and 2 are night-vision compatible.
What is the difference between the Holosun 407C and 507C?
They share the same housing, footprint, battery and solar system. The 407C projects a single 2 MOA dot; the 507C adds Holosun’s Multi-Reticle System with a 32 MOA circle you can run with or without the dot.
Is the HE407C-GR X2 waterproof?
Yes. It is rated IP67 and to 5,000 G of vibration, with a working temperature range of −30 °C to 60 °C.
