The SCRS Series of Holosun red & green dot sights is their newest "solar charging" rifle optics. These optics have an internal rechargeable battery with a 20k hours power reserve. These optics are also compact (short) on your rail. The solar panels charge the optic faster than it consumes battery making it last for an indefinite period of time as long as it is exposed to light from time to time.

These are 20mm tube red and green dot optics and have a 509T footprint.

The SCRS models have 7075 T6 aluminum housings, side removable batteries, are available in red or green reticles and have shake awake, and manual/auto brightness modes.

The SCRS come in an MRS version or 2 MOA dot version.

The MRS reticle versions have a 65 MOA ring and 2 MOA dot. The reticle can be toggled by holding down the "-" button for three seconds. You can use just the 2 MOA dot, just the 65 MOA circle, or both together.
