Time to gain the ability to quickly acquire a target using one of Holosun optics for rifle and carbine applications. This is the Holosun HS503CU MRS (Multiple Reticle System). It features a solar failsafe, so you never have to worry about getting a dead battery. It's got Holosun's "shake awake" feature, automatically activating the micro red dot when it senses motion. And the multi-reticle system is perfect for getting the perfect sight picture and bead on your target. Multi-coated lenses keep the unit protected against direct impacts, and reduce glare for unlimited eye relief. The 2-MOA dot sits inside a wide 65-MOA circle with 12 brightness settings for day, night, and night vision. Holosun’s Super LED sports a high-capacity CR2032 li-ion battery with up to 50,000 hours of battery life on a single charge.

Solar Failsafe and Smart Brightness

The failsafe is exactly what it sounds like: an excellent battery backup if the battery of your micro red dot ever dies in the field. With a bit of light, the unit's waterproof and shock-proof solar panel, fixed atop the body, will recharge and keep your optic running, so you never have to worry about trying to deal with backup irons over a dead optic. And thanks to the solar panel, the HS503CU is considered a smart optic: an onboard sensor can automatically adjust brightness under any lighting conditions, no manual adjustments are required.

Battle-Ready Aluminum Housing

The Holosun is made for all conditions, featuring a billet one-piece housing made from 6061-T6 anodized aluminum. The Holosun HS503CU MRS is completely sealed and waterproof, allowing it to run reliably in cold- and wet-weather environments.
