Most Helpful Positive Review Surprisingly accurate and robust optic for a competitive price!
I recently took a 2-day gun fighter carbine course and had the new Holosun HS403R mounted on a Geissele Super Precision mount, and the results were impressive. After a total of 1,300 rounds over a 16 hour course of fire, the optic still remained zeroed, even after being knocked around barricades and...

Holosun HS403R

by Durbo, Verified Owner from FL, United States Written on October 3, 2024
I have a few Holosun optics both red and green and have been satisfied with them. Optics Planet had a great price and fast shipping on the HS403R but when I installed the battery it was difficult to see the dot inside the house. I installed the optic on my AR 9 and took it outside to my little range on my property and I experienced a light red blur. Maybe I got a lemon this time. Like always OP has an awesome return policy so I printed their prepaid shipping label and sent it back. I haven’t given up on Holosun.
Pros:
  • GREAT PRICE
  • easy installation
Cons:
  • Blurry on all settings
Would recommend: No

Holosun 403R

by Alfy, from WA, United States Written on July 23, 2024
Boringly good optic. Does as it should. I appreciate some of the design details such as the recessed turrets which protect them from accidental adjustments. Additionally the turrent caps have an integrated tool and directions for windage are printed below. The adjustments for the brightness settings and windage offer a satisfying tactile click when adjusting so there's no guessing. The only flaw really is the flimsy mount which hosts one recoil lug, but the optic itself is solid and rigid. Unfortunately, not an ideal candidate for night vision but again as a budget offering it delivers for a sub $200 optic. Just expect to eventually change the mount, luckily the 403R uses an aimpoint micro footprint so finding an aftermarket mount is super easy (giessele, ADM, MI, Reptilia...). Overall, I definitely recommend this optic to anyone but expect to change the optic mount if you're an individual that runs your gear pretty hard.
Pros:
  • Brightness
  • tactial turrets
  • Tactile adjustments
  • Aimpoint micro footprint
  • Durable optic housing
Cons:
  • night vision
  • optic mount
Would recommend: Yes

Holosun HS403R

by Raymond, Verified Owner from TN, United States Written on June 26, 2024
As many of you already know, there is a lot of companies producing red dot optics for firearms. Holosun has been my choice of optics from 22LR to 12 gauge bullpups. When target acquisition is demanded quickly, Holoson is where I place my trust , money and life on the line. With a superior product and longevity, Holosun is where to go.
Best Used for:
  • Target acquisition less than 100 yards.
Would recommend: Yes
