The OMSsc takes on all the latest product design and functionality of Shield Sight's RMSsc and combines it with a World First Panoramic roof to offer a whole new concept in Micro Red dot design. The inclusion of their new panoramic roof gives users an unobstructed field of view and a sight picture like never before, allowing more light onto the photo diode to give a much more precise level of LED output. The transparent frame also provides a sharp and clear reflective surface resulting in a brighter lens for a clearer image and reticle. This model features an all-black finish and an 4 MOA reticle for a less intrusive reticle and more precise shooting. Included is a CR1632 3V lithium battery along with a sighting tool. A package of mounting screws are included (2x M4x8mm; 2x M4x10mm) are included.
