Questions & Answers
If there is a quick disconnect on a he510c gr, why would I need another quick disconnect such as this one? Expert Answer

If you have a Holosun HE510C Elite 2MOA Reflex Green Dot Sight with a Quick Disconnect mount you don't need this OpticsPlanet Exclusive American Defense Manufacturing Holosun 510C Quick Detach Mount. However, this OpticsPlanet Exclusive American Defense Manufacturing Holosun 510C Quick Detach Mount has a larger lever that makes it easier to manipulate.

High quality and perfect fit by Sh, April 15, 2021
Super high quality and fits my 510c like a glove. The outer edges of the mount match perfectly with the outer edges of the 510c base. Adjustment of the qd lever is easy and doesn't require tools. Highly recommend.

ADM quality. by nateski, Verified Owner, February 27, 2019
I'm not sure if there are variations in Holosun's optics that accounts for the experience the other reviewer had. This fit perfectly for my Holosun HS510C-GR. Solid lockup like all the other ADM products.

This mounts up perfectly to the 510C and looks better than the stock QD mount, its lighter weight too. The way the pockets are machined around the screw holes makes it easy to drop the screw in and get it lined up, especially at the front. The price ...
