I was looking for a reliable, durable optic with a crisp green reticle that could perform well in various lighting conditions. The Holosun 507C promised all that with its ACSS Vulcan reticle and solar failsafe technology. The green dot option was especially appealing since green tends to stand out better to my eyes in bright environments compared to red.
