Larue Lt105 Acog Compact Mount

The Larue LT105 ACOG compact mount is a purpose-built quick-detach solution for shooters running Advanced Combat Optical Gunsight (ACOG) optics on AR platforms and other tactical carbines. Built by Larue Tactical, a company known for precision mounting hardware, this compact mount bridges the gap between a full-size ACOG mount and minimal-profile setups—ideal for hunters, competition shooters, and defensive rifle builders who need repeatability without excess rail real estate.

Larue mounts earn their reputation through uncompromising tolerances and reliability in the field. The LT105 compact design means less overhang, a lower profile on your upper receiver, and the ability to co-witness iron sights or pair your ACOG with backup optics more naturally. If you're building a working rifle rather than a safe queen, this is the kind of detail that matters: a mount that holds zero, releases cleanly, and doesn't demand you reconfigure your entire upper to make it work.

This mount carries the Larue name because it's engineered to the same standard as their award-winning scope rings and bases. For AR owners, precision rifle builders, and hunters who trust their optics to stay put, the LT105 offers the compact footprint and rock-solid repeatability that separate a truly capable rifle from a collection of loose components.
