Overview

This machined aluminum mount is designed to secure the Sniper Tool Designs Angle Co-Sine Indicator directly to a MIL STD 1913 rail, keeping the unit positioned above the rail for a clean setup. It also fits M16/AR-15 flat top rifles, making it a practical option for shooters who want a dedicated mounting solution without altering the rifle’s finish. Two soft-point set screws help hold the mount in place without marring the rail, and the mil-spec hard coat anodized black finish gives it a restrained, field-ready look. Built from aircraft-grade aluminum, it offers a compact mounting footprint for users who need the ACI integrated into their rifle system.

Considerations & Trade-offs

  • Designed specifically to mount the Sniper Tool Designs Angle Co-Sine Indicator (ACI) to a MIL STD 1913 rail, so it is a dedicated accessory rather than a general-purpose mount.
  • The mount sits above the rail, which may affect how much space is available around other rail-mounted accessories.
  • It is sized for M16/AR-15 flat top rifles as well as MIL STD 1913 mounts, so compatibility is focused on those setups rather than universal fit.
  • The black anodized aluminum finish and soft point set screws are practical details, but the product is still a mounting solution for an ACI—not a standalone angle indicator.
