The Larue Tactical LT660 Micro 1/3 Cowitness Mount is a precision optics mounting solution designed for shooters who run both magnified optics and co-witnessed backup sights on the same platform. Built on LaRue's reputation for rock-solid repeatability and zero shift, this mount positions your primary optic at 1/3 lower receiver height—the cowitness plane that allows you to aim through your scope while keeping iron sights visible in the upper third of your sight picture. It's the practical choice for serious AR platform shooters running magnified optics who want redundancy without the weight and complexity of full-height rings.
The micro profile keeps your overall system profile low while maintaining the cowitness relationship, making it an efficient choice for hunting, tactical training, or any precision rifle setup where you value both optical clarity and backup sight alignment. LaRue's manufacturing process and attention to tolerance control mean your zero stays put—no creep, no surprises between range trips and field use.
If you're building or upgrading an AR-pattern rifle and need a dependable way to integrate a magnified scope with co-witnessed iron sights, this mount delivers the precision fit and reliability LaRue is known for. Whether you're dialing in for long-range hunts or running a duty-ready carbine, the LT660 Micro 1/3 Cowitness Mount handles the job without fuss.
A 1/3 cowitness mount positions your optic so that your backup iron sights are visible in the upper third of your scope's sight picture. This gives you both magnified aiming and a secondary point of reference without needing to remove the scope or shift your head. It's practical for shooters who want redundancy on a single gun.
This mount is designed for AR-pattern rifles with top-mounted Picatinny rail systems. Verify your rifle's rail system matches this standard before purchasing.
The LT660 is a picatinny-rail base mount. It will work with any optic that uses standard Picatinny rings or mounts, provided the rings and optic combination fit the available rail space.
LaRue is known for precision manufacturing and strict tolerances that minimize zero shift and creep. Their mounts are built to hold their zero through repeated shooting, cleaning, and remounting—a reputation earned through consistency over decades.
