Overview

This machined aluminum mount is designed to secure the Sniper Tool Designs Angle Co-Sine Indicator directly to a MIL STD 1913 rail, with compatibility also listed for M16/AR-15 flat top rifles. It uses two soft-point set screws to help avoid marking the mount, and it positions the ACI above the rail for a clean setup. Finished in black hard coat Type III anodizing, it offers a compact, purpose-built way to integrate the indicator into a rifle system. For hunters and shooters who want the ACI mounted on the rifle rather than carried separately, this is a straightforward accessory with a focused role.

Considerations & Trade-offs

  • Designed specifically for the Sniper Tool Designs Angle Co-Sine Indicator (ACI), so it is not a general-purpose mount for other accessories.
  • It attaches to a MIL STD 1913 rail and also fits M16/AR-15 flat top rifles, which narrows it to compatible platforms rather than universal use.
  • The ACI mounts above the rail, so the setup adds height and may change the profile of the rifle-mounted indicator.
  • At 1.37" wide and 1" high, it is a compact mount, but the small footprint means fitment should be checked against available rail space.
