❓ Holosun SCRS Mount FAQs

Is the Holosun SCRS compatible with 509T mounts?

Yes. The Holosun SCRS shares the exact same mounting footprint as the 509T, so any mount made for the 509T will work for the SCRS.

Do QD mounts retain zero after removal?

High-quality QD mounts like ADM and BOBRO are engineered to return to zero when reinstalled—perfect for optic swapping or field maintenance.

Can I co-witness my iron sights?

Yes. Mounts are available in absolute and lower 1/3 co-witness heights depending on your setup and BUIS height.

What’s the best mount for a tactical AR-15?

We recommend a lower 1/3 co-witness QD mount, like the ADM or Scalarworks, for speed, backup sight visibility, and rapid removal.
