Most Helpful Positive Review completes the 510c
I got this mount on all my HS510c optics. It provides a stronger lock up on the rail and looks better than the stock qd mount. Grab one and try it out, especially if you get a 510c on sale for $250 or less (check out Simmons sporting goods). The tactical lever is the best option for this mount over the standard. The extra lip provides the room you’ll need to release the mount from the locked position. The standard lever sits too high under the optic and makes releasing an obstacle course.

Just buy it!

by James Meadows, Verified Owner from WV, United States Written on November 22, 2024
I have had this optic for 4 or so years and just found this mount looking for a riser. Ordered it and it completes the Holosun. The worst part of the Holosun is the cheap quick disconnect. This solves the problem and makes it feel like a high end optic.
Pros:
  • Quality made
Cons:
  • None
Would recommend: Yes

Good product

by Mnice, from NC, United States Written on January 21, 2024
I hate reviewing parts that I haven’t actually used yet but I put this mount on and it seems to be made very sturdy and of good quality. Locks in secure and puts retical in the right place. Given all that I couldn’t imagine it not functioning well under fire.
Pros:
  • Everything
Cons:
  • nothing

Worthy upgrade

by Dan, Verified Owner from FL, United States Written on January 17, 2024
The 510c is an excellent optic, however the mount has a cheesy-looking and flimsy-seeming design.

American Defense makes a quality mount with a much more appealing aesthetic. The tactical lever is an improvement over the regular one too.

Perfect Replacement

by Larry, from TX, United States Written on November 25, 2023
I had been searching for a replacement for the QD mount that came with the Holoson S510C that I damaged. OpticalPlanet was the only on site where I could find a replacement. This was a perfect fit and came with the mounting screws.

Thank you.

lower 1/3 heavy duty mount

by Ron, Verified Owner from MI, United States Written on October 9, 2023
In my opinion this is an awesome upgrade for your HS510C. It can give you a Lower 1/3 witness without buying the spacer, and it seems like a robust Mount.

I give this product 5 stars and I’m very happy with the product and Optics Planet.
