Thanks to our innovative LED projecting sight adjustment system, we are introducing a compact but rugged optic for the handguns in both commercial and military markets. The objective lens covered by 6061-T6 Aircraft Quality Aluminum body ensures that the operator can maintain the original zero safe from the external contacts. Both circled Red dot and single Red dot support the fast target acquisition and greater situational awareness in performing your missions. It is compact in size, and light weight. It mounts on either a dove tail slot or a machined slide. This optic offers many features, such as easy battery replacement without re-zeroing, auto brightness adjustment control, motion sensor for auto stand-by mode. It works with major pistols such as Sig Sauer, Glock, Springfield and others.
