Top Features of this Holosun Red Dot Sight
Design
The Holosun 507C X2 is computer numerical control (CNC) machined A high-strength aerospace aluminum alloy (yield about 503 MPa / 73 ksi, roughly 1.8x that of 6061-T6) for only a few percent more weight. The go-to for duty and hard-use pistol optics, often forged.Full comparison →-aluminum giving it a rigid, lightweight chassis. The sight weighs only 1.5 oz and is 1.8 inches in length and 1.2 inches wide. The sight has the same footprint as the Trijicon RMR and will fit any milled slide or mount for the RMR.
The HE507C-GR X2 has a low-profile rounded top that is 1.6 inches high, providing a 0.63-inch x 0.91-inch viewing window. The sight’s rounded top and protrusion-free sides enable snag-free operation advantages when drawing and operating in conjunction with tactical gear.
The sight sports a water An optic's Ingress Protection (IP) code from IEC 60529: the first digit rates dust (0 to 6), the second rates water (0 to 8). A digit shown as X was simply not tested.Full comparison → of A full IP code meaning dust-tight (first digit 6) plus temporary immersion to 1 meter for 30 minutes (second digit 7).Full comparison → rating, making it suitable for continuous immersion in depths up to 1 meter for half an hour. With an IP67 rating, you can operate the sight in pretty much any environment without fear of damage from moisture or dust.
Reticle
With the 507C-GR X2, you get 3x reticle options. There is a 2 Minute of Angle (MOA) green dot for use when precision is vital. When target acquisition is the priority, you can switch to a 32 MOA green ring reticle. You can use both the 2 MOA green dot and the 32 MOA ring simultaneously. When switching between these reticle options, you won’t have to worry about re-zeroing as the sight will maintain Point of Aim (POA) / Point of Impact (POI).
The reticle is illuminated with the new Super Green LED. The LED was created by Holosun Technologies to be four times more efficient than their standard red diode. The green LED is power efficient even when set to the higher brightness settings.
The sight has 12 brightness settings. Ten of the settings are for daylight conditions. The two additional settings are night-vision compatible. With this many illumination brightness settings, shooters will have no problem dialing it into any light condition.
A green dot is a great option for people with protanomaly, a fancy word for vision with reduced red light sensitivity.
Operation
Holosun Technologies have included their Shake Awake feature in the HE507C-GR Elite green dot sight X2. This feature allows the optic to go into sleep mode when it does not detect movement after a user’s specified amount of time. When the sight senses motion, it will turn itself on to the last brightness setting used.
The Shake Awake aids in battery power conservation and allows for an always-on operation of the sight, which is mandatory for professional use or self-defense applications.
Also included in this green dot sight is Holosun’s Solar Failsafe feature. Amazingly this optic can power the illumination completely from an ambient light source. The 507C X2 also incorporates power from a A 3-volt lithium coin cell, 16mm across, holding about 120 to 140 mAh. It powers many micro and subcompact pistol optics that trade runtime for a smaller footprint.Full comparison → lithium coin cell battery. The battery and solar array give it an operational battery life of up to 100,000 hours. It will be years before you will have to change this battery.
Mounting
The 507C X2 has an industry-standard footprint. For comparison, this sight will fit the Trijicon RMR mounting footprint.
The sight comes ready to mount on a standard Picatinny standard rail interface. Using the provided Picatinny mount, the sight has a single recessed machined hex bolt for snag-free operation. The 507C makes a great MRDS option for shooters, hunters, or law enforcement professionals.
Depending on your application, you may need a different mount to achieve co-witness with your iron sights.
