Holosun 509T Details

The 509T features a Multi-reticle System and Solar Failsafe technologies. It comes alive via Shake Awake technology, improving battery life. A CR1632 battery lasts up to 50,000 hours using 2MOA dot. Solar Failsafe extends battery life, ensuring shooters always have a powered sight ready to go. Meanwhile, a side-mounted tray enables battery replacement.

The 509T comes enclosed in a titanium housing to protect the LED by keeping the elements and debris at bay, according to Holosun. The optic features IP67 ingress protection for a dust-proof, water-resistant platform. It weighs just 1.72 ounces, a compact, lightweight design.

The optic enables the shooter to choose a reticle option to suit their needs. The Multi-reticle System provides a 2 MOA Dot-only, or a 32MOA/2MOA Circle-Dot option. The 509T features 12 brightness settings for performance in all lighting conditions. It includes two Night Vision compatible settings. The 509T remains parallax free with unlimited eye relief.
