A sight aimed at the competitive shooter, the RMSx was specifically designed to answer a call from the competitive marketplace for a Shield Sight with a larger lens. The lens is 80 percent larger than their current Mini-Sight range and is available with the option of Hard Dip Coated Acrylic or new for 2023 a Deluxe glass lens. Due to the larger lens, the RMSx will help shooters to find the dot earlier in many scenarios. Most commonly when entering or exiting shooting areas and being forced to take shots while not in a stable position, allowing for faster first shot times as the shooter is able to find the dot earlier and to decrease shot-to-shot times by allowing the shooter to stay with the dot during recoil.Features :Parallax FreeOne 3V Lithium Battery, Cr2032Housing Material: AluminumCompatible With Night VisionScratch-Resistant Ultra Clear Glass Lens4Moa Dot
