Overview

This low-profile riser mount is designed for compact red dot optics, including models like the Bushnell TRS-25, when a lower setup is preferred on a Picatinny rail. It sits .48" above the rail and is 1.35" long, making it a compact option for streamlined mounting. The mount does not co-witness with AR-15 iron sights, so it is best suited for users who want a dedicated optic setup rather than a backup-sight alignment. Built by American Defense Manufacturing, it includes the Patented QD Auto Lock lever system for use with both in-spec and out-of-spec rail systems.

Considerations & Trade-offs

  • This is a low mount for small red dots, so it will not co-witness with AR-15 iron sights.
  • The mount is designed around compact optics such as the Bushnell TRS-25, so fit and use are more specialized than a general-purpose riser.
  • At 1.35" long, it offers a compact footprint rather than extra rail coverage.
  • The QD Auto Lock lever is intended to work with both in-spec and out-of-spec rail systems, but users should still confirm compatibility with their setup.
