Holosun Micro Red Dot Sight Review

Posted on: September 4th, 2014 by Will Rodriguez

I’ve been searching for a quality micro red dot for my AR15 and just couldn’t justify spending around $600 for the outstanding and battle proven Aimpoint Micro H-1 red dot sight.  I discovered the Holosun PARALOW HS403A Red Dot Sight and after two weeks of kicking the tires I couldn’t recommend a better solution.

The Holosun HS403A micro red dot measures 2.8” long and 2.1” wide (essentially the same size as the Aimpoint H-1) and claims a 50,000 hour battery life off of one common CR2032 battery using an LED illuminator.  It features a crisp 2 MOA red dot with 12 brightness settings.  The first three settings are night vision settings and the brightest settings are visible on the brightest sun filled days.  The sight features an automatic eight hour shut off function to conserve battery power and will automatically come on with a slight tap to the weapon.  Brightness adjustment is straightforward with two rubber covered buttons on top.  You can hold both buttons down to turn the sight off.  Adjusting the sight is also straightforward with adjustment knobs on the top and right side.  A nifty little feature is the caps also serve as an adjusting tool so you don’t have to pull out a flat tip screwdriver.

On the surface, the HS403A would appear to be yet another compact, lightweight red dot but what really captured the attention of shooters everywhere was its advertised battery life. According to the manufacturer, their red dot optic will run approximately 50,000 hours before a battery change is needed!
