Reviews of Holosun HS403A
Auto-switching: The auto- shutoff function is a convenient feature. The aiming system can immediately set for use. As its evolution, it comes with adjustable beam power up to the most advanced models.
One of the most interesting features is Holosun advantage technology. Thanks to it the very long life cycle of batteries. It integrates into the power supply system of the dot. The auto shutoff mode automatically adjusts the brightness of the reticle/point according to ambient light conditions. All the hidden housings mounts are made to CNC with T6061T6 aluminum treated with plasma electrolyte oxidation. That makes fewer to block your view.
Red dot small and compact, which uses new, LED technologies. That can carry a CR2032 battery up to 50,000 hours of life. An LED light has the possibility to have the edge with the microdots. The device is activated with a slight visual movement. That can be installed on various firearms such as shotguns, pistols, rifles, and crossbows. A special glass treated with a multi-layer finish is used to ensure a clear vision with the intent. That ensures zero parallax phenomenon. We find the red dot with a 30 mm tube.The microdot category incorporates different variants of dots tubes comparable to the Micro T1 / T2 as dimensions. There are many variations to choose from, each with unique features to satisfy the different needs and preferences of the shooter. These differences concern the position of the battery section. The type of power supply can be solar or traditional. The type of housing used the equipment kill flash or flip-up dust cover the presence or absence of the ignition system.
The number of models has different functions. You can see a holosun HS403A review from the individual product sheets to find the most suitable type. Starting from the entry-level model you will get solar mode, protection for the adjustment towers, switchable dot, kill flash and QD mount, in practice of the high-level features. The Holosun microdots are perfectly compatible with all market mounts dedicated to the micro Aim point T1.
In the open reflex category, there are several models of reflex sight differ in the size of the acquisition range, ranging from open sight models. The last category concerns the laser lighting / pointing systems. In this case, Holosun offers us different solutions. It goes from the simple laser pointer as with single function with a double laser.

Frequently Asked Questions
Some Red Dots come with copper-lenses that have clear plastic screens, and can function as protectors for this purpose. These lens covers are weaker than the lens itself and lend themselves more to prevent them from being scratched or suffering minor damage to that order. This lens covers also, slightly compromise the visual clarity of the aiming system, making it more opaque.
There are firms specializing in the reconstruction, repair, and maintenance of optical materials. A specialist can handle the maintenance of engineering measurements with a little lamp fixed on a tripod. We hope they solve most of the problems in that regard.
Holosun HS403A is comparable to the Aim point comp 2 standards. The type of characteristic that differentiates the product dictates the differences in price. The absence of the solar system the possibility of switching is between red dot and circle dot prerogative of the 500 series. Holosun hs403a offers in even more variants the differences are given by the use of the solar system. The ability to switch the type of dot and the housing model used in the upgraded versions model DU / CU. Where the place for upgraded uses, a different type of design for better protection of the adjustment towers. The series offers to have a laser pointer integrated into the dot monocular structure visible green, red pointer, air pointer in different combinations.
