Special Features
- The Flat Dark Earth finish coordinates directly with FDE handguards, stocks, and furniture, giving tan and earth-tone carbine builds a cohesive, matched appearance without painting or wrapping the optic.
- Solar Failsafe keeps the reticle powered in any lit environment even after battery depletion, removing battery failure as a single point of failure on a duty or hunting rifle.
- The titanium-alloy hood shields the emitter and lens from direct impact, muzzle blast, and transport damage that unprotected open emitter designs cannot withstand.
- The Multi-Reticle System delivers three aiming configurations: 2 MOA dot only, 65 MOA ring only, or the full circle-dot combination for close-quarters through mid-range work in a single optic.
Practical Benefits
- The large 0.91 x 1.26 inch window and unlimited eye relief give you a wide, unobstructed sight picture that makes the reticle fast to find on a rapid mount across carbine, PCC, and shotgun applications.
- The included QD mount installs tool-free and puts the dot at absolute co-witness height, so the HS510C-FDE-R goes straight from the box onto any standard Picatinny rail without additional hardware.
- Your HS510C-FDE-R gives you a solar-backed, titanium-protected, FDE-finished red dot that stays powered, stays matched to your build, and stays ready without checking batteries before every range session or hunt.
The Holosun HS510C Open Reflex Sight (HS510C-FDE-R) with its 65 MOA ring and 2 MOA red dot in Flat Dark Earth is a smart addition for carbine and PCC shooters who want a large-window solar-powered open reflex sight that matches their tan-finish build without sacrificing any features.
