I found the 510 sight to be a bit too low. The riser was very easy to install and fits like a glove. You would never know the sight was raised up.
Exactly as advertised

Moves the 510C from absolute to 1/3 cowitness. Does it well!

This will put you just above the A2 front post on Carbine, I don’t like co-witness I prefer above it and it’s a clearer shot and less clutter when aiming down site, oh PA is best in class when comes to shipping

Finally and worth the wait.

Perfect fit. Raised to lower 1/3 which I prefer especially with my fsp AR.

Purchased this riser for the Holosun 510C. Without it, the RDS has absolute co-witness and I would prefer 1/3 co-witness. This riser achieves just that. Easily installed. Remove the bottom place on the sight, install this plate, then reinstall the clamping plate to the sight and then the whole unit to the Picatinny rail on the AR.
