Core Features

Window Size

The window size is similar to the Trijicon RMR with a slightly larger area near the top of the lens frame.

Just about couple milimeters taller to helps pistol shooters track the reticle better inside the lens.

As far as the window width goes, it feels the same as a Trijicon RMR.

Lens Tint

The Holosun 507C X2 has a bit of bluish lens tint but it's not so distracting that you can't see things clearly through the lens indoor and under the sun.

The anti reflection multi coating layers makes the lens scratch proof under normal use, and it keeps the reticle projection much more crisp on the lens for shooters with astigmatism.

Astigmatism varies from person to person, and an optic optimized for astigmatism is only as good as the shooter's vision.

Build Quality

The black andoized Holosun 507C X2 just looks amazing and feels rock solid right out of the box no doubt.

The mounting footprint extrusion and every corner of the body is well machined and feels like a high premium $600 optic.

The base construction and the lens frame feel much more beefier and thicker than the Trijicon RMR for added durability.

The hood of the lens is much longer than the RMR as well.

Yes it's recoil proof as we tested on a FNX 45 Tactical and a 12GA Benelli M4 under normal use.

Reticle

The 507C X2 uses a 2 MOA center dot by default, and it has the option to use:

2 MOA dot ONLY
2 MOA dot + 32 MOA ring
32 MOA ring ONLY

To cycle through all the options, just hold the "-" button for 3 secs.

Make sure it's NOT in the lockout mode

Very easy to pick up

The 2 MOA dot size reticle does the same thing other optics can do for precise aiming that covers a 2" diameter circle at about 100 yards.

The 32 MOA ring can be used to:

Estimate known target size distances without a magnifier
Faster for the eye to pick up
Use it as shotgun spread pattern (Depends on pellet types & choke configuration)

However, when the optic is too far forward from the eye, the reticle appears to be bigger than 32 MOA, which can skew your point of aim or sizing of a target down range.

Brightness Lock Out Mode

The reticle brightness lock out mode is something conceal carry users always wanted to prevent inadvertent button press under a piece of clothing that throws off the desired setting. Either too bright or too dim.

12 brightness settings
10 daylight
2 night vision

Once the Super LED brightness level is set, the user will hold the "+" button for 3 secs to save and lock it.

The reticle will flash once and that's how you know it's saved.

Just that simple!

If you have astigmatism, having a wide range of brightness increment settings can help the user get the best setting that work for them.

Elevation & Windage Adjustments

The elevation and windage adjustments are just like other red dots

1 MOA / click feels very positive with total +/- 50 click range

The user can use the provided tool for positive click adjustment or use a shell casing lip.

Battery Compartment

Access the battery from the side instead of the bottom is the best design that other open reflex red dots are taking into consideration.

Just unscrew, pull the tray out, and replace the battery.

Sight removal for battery placement is no longer required. This saves time re-zeroing the sight and save effort looking for tools.

Be Cautious: The screw is very small. Don't lose it!

Solar Failsafe Works Like A Fiber Optic

The Solar Failsafe technology extends the battery life longer to keep you in the fight longer without ever changing the battery.

So how much solar juice can you get?

So we tested the sight without the battery under the sun and here is what we discovered:

The sight acts almost like a sight with fiber optic, but the reticle disappear if you block off lights to the solar panel. The only downside is that once the sight is in a dark area, it turns off and doesn't turn back on even when light returns until buttons are pressed.
