The Holosun HS510C+HM3X Red Dot/Magnifier Combo Kit is a simple, effective setup for shooters who want a single sight for close- and mid-range use. The Holosun HS510C works as a Red Dot Sight for quick target acquisition at close range. When you need more reach, the Holosun HM3x adds 3x magnification to help you see targets at distance. This Magnifier Combo gives you clear, fast sighting without swapping optics or changing your setup. The HS510C uses the Multi Reticle System. You can pick between a 65 MOA ring with a 2 MOA center dot, the 2 MOA dot by itself, or the 65 MOA ring alone. These options let you adjust based on shooting style, lighting, and target size. It also runs on both sunlight and a battery. This setup can keep going for up to 50,000 hours, so you don’t have to worry about losing power. The HM3X sits behind the sight and flips to the side when you don’t need the extra zoom. The flip mount works smoothly and is easy to use with either hand. For those who may have seen the name spelt differently, the sight is sometimes referred to as the Holoson 510C. You may also see it listed as a Holosun red dot magnifier combo or simply Holosun with magnifier. All refer to the same type of setup: a fast red dot paired with a side-flip magnifier. This kit is built with strong materials to handle real use in the field, on the range, or for duty work. The housing is rugged, and the optics deliver a clear, sharp sight picture. With steady zero retention and repeatable returns when flipping the magnifier in and out of view, it’s dependable for both casual and serious shooters.
