Apex Tactical has recently released their Sig Sauer P320 Optics mounts designed for mounting the Aimpoint ACRO or the Steiner MPS.

Apex Tactical states “The Apex Optic Mount is designed to securely mount the Aimpoint® Acro series or Steiner MPS optics to the slide of the Sig Sauer P320 Legion, P320 M17/M18, and other models featuring the R2 slide cut.

The Apex Optic Mount comes either with or without an integrated rear sight.

The integrated rear sight also acts as a gas shield to keep class cleaner longer.

Requires a tall front sight for co-witness. Two different sight height packages are available.”
