The 507Comp-RD is a compact red dot sight featuring a compact and low-profile design, a target reticle Competition Reticle System (CRS) with 8 characters and 10 levels of illumination, battery power, and a rugged aluminum housing. Fitted for mounting on Trijicon RMR type boards.

The sight has a target mark in 8 configurations consisting of a 2 MOA dot, an 8 MOA small circle, a 20 MOA medium circle and a 32 MOA large circle, as well as various configurations of a dot with a circle alone or a dot with a small and large circle. The sign has 10 brightness levels: 8 daytime and 2 nighttime.

The power source is a single CR-1632 battery. The backlight has a "Shake Awake" function, i.e. activation from standby mode when a shock is detected. This helps extend the already considerable battery life. The sign's backlighting levels allow it to be used during the day, at night and with night vision.

To operate the device there are two buttons located on the side. On the other side is a port for a battery. The sign is vertically and horizontally adjustable and parallax-free. The device remembers the last selected brightness setting. On top of that, it has a lock function, protecting the selected settings from accidental button presses.

The body of the viewfinder is made of aluminum. It has an IP 67 rating, ensuring its resistance to weather, dirt and dust. It is adapted for mounting on an RMR type plate. The size of the lens allows comfortable observation with both eyes open, while emergency use of the company's mechanical sighting devices.

The 507Comp-RD sight is a reasonable choice for rugged, small sights with great capabilities. It will work well for sports use in the dynamic shooting category, where it is important to get the weapon quickly and point it at the target, but also for professional and recreational use.

The lens in my red dot sight is skewed, should it be like that?
Yes, in the case of enclosed red dot sights with the emitter at 4 o'clock, the lens must be tilted to properly reflect light towards the user's eyes.
