In addition it ships with BOTH a quality low rise and high rise mount to fit virtually any suitable firearm, pistol or rifle. Unlike competing sights, there is no need to spend extra money on expensive aftermarket accessories.


Windage and elevation adjustment knobs are protected with covers until you are ready to tweak. Each click equals a .5 MOA value for a extremely wide range of adjustability.

This sight has extreme value for its feature set and build. Although new to the market, HOLOSUN with their innovation and out of the box designs is quickly becoming a market leader and household name. Don’t waste your money on expensive "brand priced" sights. Get a HOLOSUN that is every bit of good (if not better) and STILL have some money left in your wallet.

Holosun Red Dot
For reasons I can't explain, this red dot eliminates parallax better than any other I've tried. Other shooters testing my weapon agree. One caveat: It helps to add some dielectric grease to the O rings; particularly the one for the battery compartment. Otherwise you may not be able to tighten the cover down enough to make reliable contact with the battery.

This red dot was perfect for my Ruger Mark IV 22/45. It was shipped promptly and showed up in perfect condition. Set up was very easy and I was shooting very tight groups at 15 yards in minutes. I would definitely recommend this if you’re thinking about getting into the red dot technology. I really like the adjustable size and light intensity of the red dot.
