Holosun 509T Raises the Bar for Pistol Optics

City of Industry, CA (June 16, 2020) – The 509T enclosed reflex sight is the new flagship pistol optic in the Holosun line-up and for good reason. Shooters will appreciate the ultra-durable enclosed design, Multi-reticle System, and Solar Failsafe technologies. The 509T is a “set it and forget it” sight that snaps into action when the shooter is ready thanks to Shake Awake technology. The incredible battery life and performance qualities make this sight a major tactical asset for any shooter.

Holosun incorporates industry-leading battery efficiency technology into every sight offered. The 509T is no exception with CR1632 battery life lasting up to 50,000 hours using the 2MOA dot only.  Solar failsafe extends battery life ensuring shooters will always have a powered, active, and effective sight. A convenient, side-mounted battery tray makes for easy battery replacement.

The 509T is enclosed in a titanium housing that protects the super LED by keeping the elements and debris at bay. The 509T features IP67 ingress protection for a dust-proof, water-resistant package. At just 1.72 ounces, the 509T is a compact, lightweight design that makes for a natural extension of the pistol.

The 509T lets the shooter choose a reticle option that suits their needs. Holosun’s 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 including 2 Night Vision compatible settings. The 509T is parallax-free with unlimited eye relief and provides a clear sight picture thanks to multi-coated optical glass lenses.
