Holosun 507Comp‑RD — a sight adapted to the shooter's needs

The reticle is available in 8 configurations composed of a 2 MOA dot, small 8 MOA ring, medium 20 MOA ring and large 32 MOA ring, as well as various dot‑plus‑ring combinations. The reticle offers 10 brightness levels: 8 daytime and 2 NV (night vision) compatible.

The sight housing is made of aluminum and carries an IP67 rating for resistance to weather, dirt, and dust. It is prepared for RMR plate mounting. The lens size allows comfortable two‑eye use and provides the option to fall back to factory mechanical sights in emergencies.
