Most Helpful Positive Review Unproven, but awesome so far
Glass has better optical quality than Aimpoint T2. Circle dot reticle is crisper than Eotech in a much smaller and lighter package. More than bright enough for any situation on this planet. The mount sucks. The optic is compatible with all aimpoint micro mounts, but center line is 3-4mm higher than ...

Most Helpful Negative Review Terrible Reticle, Returning for Refund
The optic seem well made and looked nice, until i turned it on. The reticle had terrible blurring. So bad it looked like one big blob on high setting and what looked like a double smeared reticle on lower power. Completely unusable and needs to be returned. Waited a month for this sight after Op...

HS503R review

by vh, Verified Owner from OH, United States Written on April 3, 2025
Good optic and got for a good deal. The red dot function between dot, and dot with circle took a bit to figure out to since it's different than other red dots I've had. Looks good on my shotgun.

Great Red Dot Sight!

by Frank D, Verified Owner from PA, United States Written on April 8, 2024
Bought one of these for my AR-15 and one for my wife’s AR-9 PCC. Very satisfied with them. I like the easy battery access and the rotary brightness adjust knob rather than push buttons. The brightness of the dot is sufficient for bright sunlight. When using the weapons light pressure switch on my AR15, I don’t lose the red dot when my brightness setting is correct on the sight.
Pros:
  • great eye relief, clear lens.easy controls
Cons:
  • The mount could be a little more robust where it attaches to the rail
Best Used for:
  • AR-15 and PCC platforms
Would recommend: Yes

Holoson HS503R

by A-A-ron, from IA, United States Written on August 29, 2022
Great optic and got for a great deal on OP. The red dot function took a bit to get used to since it's different than others I've had. Looks perfect with the Scalarworks mount. It doesn't have the largest sight picture but enough for a cqb riffle.
Pros:
  • Price
  • Functionality
  • Looks
Cons:
  • Not the largest sight picture
Best Used for:
  • carbine
  • Home defense
Would recommend: Yes

Amazing optic

by Brady, from UT, United States Written on January 19, 2022
The sight fits the rail perfect and looks great. There was no movement after 300 rounds. I love the variety of sights you can use. The adjustments are easy and it was simple to sight in. I’ll be buying another.

Great micro red dot

by iWreklives, Verified Owner from CT, United States Written on July 30, 2020
I run this off set with a 1-4 LPVO and I love everything about the optic bucks except that it is made in China. I can’t deny the quality and price for this optic. Glass is clear, controls simple and textile. Great red dot for a offset or main optic on any rifle.
Would recommend: Yes

great reticle. no motion on/off

by Donovan Brink, from NY, United States Written on June 25, 2020
i love the eotech style reticle. crisp, clear, easy to identify. has several useable hold overs for different ranges and the ring of death for pretty much guaranteed a zone hits at any distance. great for cqb. option to switch to single dot is nice. only complaint is it does not have the motion sense on/off like many other holosun red dots that cost less money. about 450 rounds in an its held zero with no shift at all.
Pros:
  • ring of death reticle, daylight bright, nv compatible, dual reticle
Cons:
  • No motion activation
Best Used for:
  • CQB - 200 yards
Would recommend: Yes

Better than Trijicon

by Holosight reviewer, from TX, United States Written on April 26, 2020
This sight came with a CMMG 9mm pistol I purchased. My father and I took both his (300 blk) and my (9mm) banshee's to the range to test out, and this sight viewed far better than his Trijicon MRO. The Trijicon showed substantial echo past the initial setting vs the clean Holosun recital. Sure, its 2 MOA so there will be some blur, but all around impressed.
Pros:
  • easy to use
  • Clear optic
Cons:
  • Not gold
Best Used for:
  • Home Defense
  • recreational plinkers
Would recommend: Yes
