Holosun 407C X2

Made of durable 7075 T6 aluminium with an anodised finish, the same metal used in good AR-15 rifles. Waterproof up to 1 m depth.

The “shake awake” feature means the device will power off automatically after a few minutes of not detecting movement, and will power on immediately after detecting the slightest movement or vibration. However, we recommend turning off the device when not in use.

It comes with a detachable Picatinny mount adequate for high rail weapons like shotguns or the AK , G36 or MP5 platforms, as well as all the hardware necessary for its installation. We recommend applying Loctite 243 on all the screws and direct mount to a slide milled with the specific footprint of this optic (no adapter plate). The 407C-X2 shares the same footprint as the Trijicon RMR

How does the solar mode work?

The ‘C’ in the device’s denomination indicates a solar panel. The solar panel doesn’t work as most people think.

When on solar mode, the brightness of the dot automatically adjusts to ambient light conditions. When not enough solar energy to power the reticle, the device taps into the battery to compensate. In practice, we find solar mode to always produce a very weak dot, so we recommend running the device always on battery mode.

What are the differences between the 407C and the 507C?
The 407C has a 2 MOA dot. The 507C has 3 different reticle modes: 2 MOA dot, 2 MOA dot surrounded by 32 MOA ring and 32 MOA ring only.

The reason we offer the 407C is because in our experience, the 2 MOA dot is the option that makes sense for pistols and subguns – which is where most end users of this optic will place it – and is slightly cheaper.

What are the differences between the 407C, 407C V2 and the 407C X2?
The 407C was released in 2018. At the beginning of 2020, Holosun released the second generation, named V2. The X2 is the third generation of the device, released months after the V2.

The differences are:
-    The V2 and X2 versions have a side battery compartment instead of a bottom compartment, in order to accommodate the CR1632 battery.
-    The first gen had small buttons in a horizontal layout, the V2 has larger buttons placed vertically, the X2 went back to the original layout.
-    The X2 introduced a button lock-out feature to prevent accidentally pressing the buttons.
