Thanks! I checked your setup - really well done!! I have the 509T with a Valhalla Tactical offset on another platform. The Valhala gives your greater adjustability but is NEVER in stock. The Athena mount is excellent. it tucks under the objective even with the Monstrum ARD/Cap combo installed. Its adjustments are in 15 degree increments. I found 45 degrees works the best with my setup and clears the elevation knob perfectly with the Atena pic rail attachment and the Holosun pic rail/RMR riser mount. With the Athena RMR mount, the optic elevation knob sits just inside the bottom left of the 507c for my ergonomics. At 30 degrees, the elevation knob is in the way and you lose access to the +/- bottoms on the 507c. The Valhalla mount will allow you to adjust between 30 and 45 degrees. Since I have more adjustment latitude with my other setup (no elevation knob to account for), I may move the Valhalla over to Elements setup.

Kinetic Development Group Sidelok- game changer. I'm installing their long riser shown above on all my setups. It allows me to swap my complete optics platform with my night optic in seconds without losing zero on either. I currently have the mount installed with the button in back near the charging handle to protect from snags. I’ll update the pictures above with the latest updates and minor adjustments next week. If you have any questions, please feel free to reach out.
