The popular HOLOSUN combo kits are based on the success of the original HS510C + HM3X model, which was sold as a package including a red dot sight, a magnification module, and all the necessary accessories for aligning the optics.
This set is suitable for sport shooters, hunters, airsoft players, and other tactical applications where you will appreciate shooting at close range and, thanks to the magnification module, at medium-close ranges as well.
The red dot sight is made of rugged hard aluminum. Combined with modern HOLOSUN technologies, it offers: a battery life of up to 50,000 hours, auto-on, auto-off, solar panel charging, and switchable reticles. You get the best military-grade product at a great price and save money too.
The package also includes a spacer for the magnification module to achieve a height of 1/3 co-witness.

The magnification module is made of durable titanium with impeccable craftsmanship. Thanks to the quick-detach (QD) mount, the magnification module can be quickly removed and reinstalled. It features crystal-clear optics with excellent eye relief and diopter adjustment of ±3 diopters. The magnification module features a sufficiently rigid mount that can be easily raised and lowered.
