Holosun HS507C X2 Open Reflex Sight with Solar Failsafe (Red Circle-Dot Reticle)

Designed for full-size pistol applications, this HS507C X2 Open Reflex Sight with Solar Failsafe from Holosun features a red, circle-dot reticle and a multicoated lens for clear and unobstructed targeting at close and long ranges. The housing and finish are made from 7075 T6 aluminum and the sight is compatible with most factory iron sights. Directly compatible with the Sig Sauer P365X and P365XL, the Holosun K footprint requires an adapter plate for slides with a four-boss interface. The multiple reticle system has three options: a 2 MOA dot, a 32 MOA circle, and a combined reticle. The sight's red Super LED is powered by a 1632 battery, providing ten daylight brightness levels and two night-vision settings, and delivering 50,000 hours of battery life. The battery is backed up by Holosun's Solar Failsafe technology, which uses solar power to keep the sight working after the battery fails.
