Mike, member, from AR, United States, asked on February 12, 2025

can I put a Holosun EPS, 508T or a 509T on this mount?

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on February 12, 2025

The Arisaka Defense Offset Optic Red Dot Sight Mount is designed to work with Arisaka Defense Offset Optic Plates. Each plate is designed to fit a specific optic footprint. For optics such as the Holosun EPS, you would need to use the Deltapoint Pro plate. For the 508T you will need the RMR plate, and the 509T has a specific plate as well. The adapter plate can be found linked below:

Answered by Hunter, Gear Expert, from OH, United States, on September 09, 2022

There are not any stems to change the height of the Arisaka Defense Offset Optic Red Dot Sight Mount. However, the included stem can be mounted to either have the sight sit at a 45 degree angle or a 35 degree angle. The mounting instructions on the left side of the product page describe this process.

Does this have a plate for the holosun HS507K X2?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on July 01, 2022

There is not an Arisaka Defense Offset Optic Mounting Plate for the Holosun HS507K. That red dot uses a Shield RMSc footprint, so the Shield RMS Arisaka Defense Offset Optic Mounting plate might work but would need to be modified.
