Holosun HE509T-RD X2 SOLAR RED DOT SIGHT

Closed micro sized red dot sight from Holosun.
The CNC-machined, matt black anodized titanium visor weighs 63 g and measures 40 x 31 x 28 mm. The IP67 protection class makes it waterproof, fog-proof and dustproof, as well as shockproof up to 1000 G.
The 23x16 mm lens glass is coated with an anti-scratch and anti-reflective multi-layer coating. It features a 2 MOA red dot and a 32 circle with 1 MOA adjustment. An LED offers two NV modes and ten brightness levels. With no parallax, unlimited eye relief and an adjustment range of 30 MOA in elevation and side, the HE509T-RD X2 guarantees fast and precise target acquisition in all weather and lighting conditions.
It is powered by a single CR1632 battery in a screw-locked compartment, which allows for a runtime of 50,000 hours at medium spot brightness. It also features rubberized controls and a "shake awake" system to help conserve battery life. The additional solar panel on the top and the "solar failsafe" system boost the brightness settings.
The set includes an RMR mount, a cleaning cloth and a mounting key.
