Most Helpful Positive Review Should be included with every 510c; but it works.
This is a plate that matches the foot print of the 510c. It is well made, matches the finish and does what it’s supposed to do. I’m removing a star because it should be included standard with every 510c.

Works good

by BrianB, Verified Owner from UT, United States Written on August 22, 2023
This really should be included with the optic. Works well and everything fits together as it should. Sight picture is still very nice if you have to run back up iron sights. If you are ordering a 510c go ahead and order this at the same time, you won't be sorry.
Pros:
  • Fit and finish
Cons:
  • Should be included with optic
Would recommend: Yes

Just what I needed

by GH, Verified Owner from TX, United States Written on October 7, 2021
This is exactly what I needed to raise the sight higher to get the 1/3 co witness. Also if anyone has issues with mounting thinking the screws are too short, there not, first mount the plate to the sight then the base to the plate. I'm new to this so it took me a minute to figure it out.

Great material, precision construction.

by Emcee, from CA, United States Written on July 14, 2021
Fits perfect and the screws even had locktite applied to the tip to ensure they stay tight. Highly recommend this product. The riser offers a perfect 1/3, which sits the optic right above the magpul flip ups. Minimal adjustment required to the hm3x magnifier.

510c riser plate

by Reid, from MI, United States Written on July 14, 2021
Is what it is. Does what it is supposed to. Fits perfectly with 510c. Shipped faster than expected given it was on backorder. How much more can I say about a riser plate. Why do these have to be 200 characters

An absolute must have

by OCTrojan, Verified Owner from CA, United States Written on April 20, 2021
I have a Holosun H510C-GR and then mounted a Holosun LE117G (laser) on my pistol’s 12 o’clock position. Because the laser sits about 1/8” too high, this HS510C riser plate allowed me to co-witness my H510C’s green dot. I still need another HS510C riser plate for my other pistol (configured with the same Holosun optic and laser).
Pros:
  • Excellent quality
  • Excellent construction
Cons:
  • Took forever to get it
Would recommend: Yes

Great 1/3 co-witness riser

by Jimmy, from MO, United States Written on April 6, 2021
Overall, its a great riser that I use for my duty rifle which takes an occassional toss/impact. I didn't need the riser until I broke my backup magpul sights and upgraded to some fixed Daniel Defense iron sights, which cluttered my area of view in my optic. Target identification is something I have to be on my game with and adding this riser really freed up some much needed area of view. The cost seems a bit to high, but the item works great and so far, no damage.

Perfect for 1/3 Co-Witness

by Ron, Verified Owner from NC, United States Written on February 25, 2021
I have an AR upper with A2 fixed front sight. The HS510C sits at absolute co-witness level. For short ranges, 7m or so you need to aim at the bottom of the 65moa reticle. With the 1/3 co-witness it sits slightly above the A2 sight and is perfect for picking up the dot at any range. I zeroed at 50m. I can shoot 1" groups at 50m and at 7m using the bottom of the reticle consistently hitting 1" groups without worrying about my hold. It is quality made, went on super easy. Applied a little blue locktite when I added it and it is holding zero perfectly. Placed my order with Optics Planet and 7 days later it was on my AR. Highly recommend the spacer and Optics Planet!

Perfect for the HS510C on X95

by Matt, from WI, United States Written on February 14, 2021
I put a HS510C on my X95 and really liked the optic and could shoot with it ok, but it felt like I really needed to push my face down to get a good sight picture. I added this which feels like a great sturdy addition and only took a few minutes to put in and it is much more comfortable and a bit easier to get the rifle up and aimed on target

Holosun 510c spacer

by Daniel, from OH, United States Written on February 6, 2021
I bought this to raise the height of my holosun 510c just a little bit. It worked out great. The website said they were on backorder for 11-13 months but I received it after about 3-4 weeks. Highly recommend this product. From my experience Holosun makes the best optics around for the price.
