    • User Friendly Design - Excellent Quality
This is an incredible product on many levels. The 'combo' of the red dot sight and the 3X magnifier is packaged in a very sturdy case with a carrying handle. The foam insert in the case is cut out to hold the red dot, the magnifier, and the tools and accessories safely for transport and storage. Or, if you prefer, the foam insert can be removed to use the case to carry ammo, etc. The actual setup on your rifle is very easy due to the "quick mount" that clamps them onto your rail. I used a laser bore sight to zero the HS510C Red Dot in a matter of 5 minutes, and it was even quicker to center the red dot in the HM3X Magnifier. This is a VERY "user friendly" product from start to finish, and it exemplifies the excellent engineering that has gone into the design and manufacturing of Holosun products... ... show more

I just received this item. Looks brand new, minimal wear on the pivot joint for the magnifier. Easy installation with toggle levers. 2 tools provided to adjust tension so you can adjust the toggle levers to fit tight and still be able to open it. Once adjusted, it fits tight with no wobble. Adjustable brightness is great for various lighting conditions. Magnification looks clear, and I like the provided elastic cover. From use with previous dot sights (5 moa) I thought I had an astigmatism. Maybe I do, but if so, this sight minimizes the starburst effect and would be completely usable. Will update after use. ... show more

    • Outstanding Performance in every way!
Worth every penny, top quality combination. Great addition to your rifle, easy installation, clear bright zero, combine the 3X with the dot opens up ability for accuracy you never imagined. The 3X flips over to still allow use of your iron sights. Top quality in every way possible, easy to recommend. ... show more

    • I love this setup!
I was running this on my 16" AR and just recently moved to 10.5". Really good setup for 100yds and in. Out past 50yd throw up the magnifier and you'll be peppering steel with confidence. Easy to zero and the batteries have not been an issue for 6+ months.
