The OMSx (Open Mini Sight XL) series is designed as a next-generation electronic reflex sight designed for high-level competition. The optic features a reinforced glass lens along with an 80% increased window size for greatly improved optical clarity, dot tracking and sight picture. A translucent acrylic roof design greatly reduces visual obstruction for greater target acquisition to give shooters the edge in a match. The OMSx is compatible with any RMS/SMS optic cut and retains the auto brightness adjust feature, IP67 waterproof rating and 20,000-hour battery life of its predecessors. This model features an all-black finish with a 8 MOA dot reticle. One CR2032 battery is included along with a mounting kit consisting of a shim, two sets of mounting screws (2x M4x8mm; 2x M4x10mm), two hex tools (1.5 & 2.5), four nylon washers and a battery cover. A plastic optic cover is also included for additional protection during storage and transportation.
