Holosun – HS403A Parallax Free Red Dot Sight (Up to 50000hr Battery Life)
No more bump for the battery! The PARALOW HS403A Red Dot scope has no external battery housing. The battery is hidden in the base where is will rarely need to be changed. This elegant design allows the scope to be simply a tube, allowing the maximum field of vision. Aiming with both eyes is now just a reflex and allows you to have maximum situational awareness. This sight includes 50,000 hour battery life, is parallax free, and has a durable PEO/MAO finish. Add to this an auto wake feature that automatically turns on the scope when it is moved and an adjustable 8 hour auto-shutoff. This scope comes with two mounts, a low profile and a AR height lower 1/3 mount.Â

MECHANICAL DATA
Housing Material   Aluminum
Housing Finish   PEO/MAO housing finish: Plasma electrolytic oxidation (PEO), also known as microarc oxidation (MAO), is an electrochemical surface treatment process for generating oxide coatings on metals. It is similar to anodizing, but it employs higher potentials, so that discharges[1] occur and the resulting plasma modifies the structure of the oxide layer. This process can be used to grow thick (tens or hundreds of micrometers), largely crystalline, oxide coatings on metals such as aluminium, magnesium and titanium. Because they can present high hardness[2] and a continuous barrier, these coatings can offer protection against wear, corrosion or heat as well as electrical insulation.
