Below are Holosuns AEMS series of optics. These red and green dot sights are offered at the best price with free shipping.

The Holosun AEMS (pronounced "AIMS") series of optics is one of their newest offerings to their rifle optic lineup. These awesome optics are underrated in our opinion.

They have large square windows - 2x larger surface area than the traditional 20mm tube optics. They have shake awake, aluminum housings, 50k hours of battery life, side removable batteries, and have solar versions with manual/auto brightness.

These optics come with a 1/3 co-witness mount and the optics themselves are compact. So they give you a large FOV in a compact size.

The MRS versions have a solar panel and attached clear lens covers.

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.

The "Core" versions have a 2 MOA dot.
