Holosun 503C


The Holosun 503C Series Optic is a 20mm micro optic designed for rifle and carbine applications. All Holosun 503 Series optics feature Holosun’s Multiple Reticle System (MRS), have 12 brightness settings and up to 50,000 hour battery life, are submersible up to 1m, have unlimited eye relief and completely parallax-free. Additionally, this 503C features Holosun’s Solar Failsafe and Shake Awake Technologies. Shake Awake technology senses motion to power the sight on and off and last setting recall ensures you don’t lose your customized options once the unit powers down.

With Holosun’s MRS, users can choose between the precision of a 2 MOA dot only, 65 MOA circle only, or a fast-acquisition 2MOA/65MOA Circle-Dot reticle. All versions are projected from the same LED, so no re-zeroing is needed when changing reticles. Enhance your shooting skills and create a better experience at the range by equipping your firearm with a Holosun 503C 20mm micro Optic, available with either red or gold reticle.

Included: Lower 1/3 Co-witness mount, Low Profile Mount, Rubber Lens Cover, T10 L Key, CR2032 Battery, Lens Cloth and Users Manual.
