The Crimson Trace Resilient Ultralite Green is a lightweight reflex sight built for shooters who need reliable target acquisition without weighing down their platform. Whether you're running a duty pistol, hunting rifle, or shotgun, this electronic sight combines practical design with genuine durability—no adapter plates, no guessing on fitment. The universal mounting pattern accepts both RMR and Docter footprints, giving you flexibility to mount it where it works best for your setup.
What sets this reflex sight apart is its engineering philosophy: less weight, same toughness. The housing is molded from high-impact polymer—the same material used in pistol frames—but tips the scales 50% lighter than aluminum alternatives. That matters when you're carrying all day or concerned about how additional mass affects your gun's handling. A 3MOA dot provides quick target acquisition, and the motion-activated sensor wakes the sight only when your firearm moves, eliminating the need to hunt for an on/off switch in critical moments.
The sight is rated IPX4 water-resistant and delivers over 20,000 hours of battery life—more than two years of continuous operation. The recessed glass lens gives you a generous field of view for fast target work at any distance. Whether you're at the range, in the field, or relying on this for personal protection, the Resilient Ultralite is built to work when it matters.
