Most Helpful Positive Review Holosun 507c
Nice crisp Dot with clear glass. RMR foot print without the RMR price. Solar failsafe and shake awake. What's not to love? Highly recommend.

Perfect on my MP5

by Jon, Verified Owner from VA, United States Written on May 28, 2026
I went to several types of optics on my MP5 I couldn’t find the perfect size or fit for it. Mounted on a scaler works riser, it’s perfect..

perfect size for my PCCs

by Jon, Verified Owner from VA, United States Written on May 19, 2026
I’m out of this on a scaler works riser on my MP5 and definitely looks the part. Radical illumination, adjust automatically based on background light

Forward facing light sensor

by Beretta 92, Verified Owner from PA, United States Written on May 12, 2026
Always pleased with Holosun red dots. Like the three optional reticles, brightness controls work very well. Best feature is the forward-facing light sensor. Adjusts brightness based on brightness of target, not brightness of light over optic.
Pros:
  • Forward-facing light sensor
Cons:
  • None
Would recommend: Yes

Holosun HS507C-x3-Rd

by Howard, from MI, United States Written on May 8, 2026
With my old eyes the circle dot lets me come on to target quickly. Being able to co witness helps. I use this on a stealth arms platypus commander. After eye conditions green cannot be seen so red works fine.

Optic and Shipping

by e90liz, Verified Owner from CA, United States Written on April 14, 2026
Holosun doesn't disappoint. I've been waiting for the x3 for my G19 and found it at OpticsPlanet.com. Once I ordered it, they shipped it out the next day and got it in the mail within a few days.
