Overview

Built for mounting high-power optics on a flattop AR-15, this extended scope mount is aimed at shooters who need more eye relief than a standard setup provides. Its 3-inch offset gives the mount a longer built-in eye relief within the ADM line, making it a practical choice when optic placement needs to be pushed forward. The quick-detach Auto Lock Lever system is designed to work with both in-spec and out-of-spec rail systems, adding flexibility for different rifle setups. It is a purpose-driven option for hunters and shooters setting up a carbine with larger glass and a more forward optic position.

Pros

  • Designed for mounting high power glass on a flattop style AR-15
  • Extended cantilever provides increased eye relief over the standard RECON
  • 3-inch offset offers the longest built-in eye relief among ADM mounts

Considerations & Trade-offs

  • The 3" offset is specific to flattop style AR-15 setups, so it may not suit rifles outside that configuration.
  • Its extended cantilever is intended for high power glass, which can make the mount more specialized than a standard-purpose option.
  • The mount is built around the 34mm ring size, so scope compatibility depends on that diameter.
  • The QD Auto Lock Lever system is designed to accommodate both in spec and out of spec rail systems, but fit should still be verified on the intended rail setup.
