LaRue Tactical Micro Optic QD Mount - Lower 1/3 Co-Witness Height, Speed Lever Locking Cam System, CNC-Machined Billet Aluminum, Matte Black Anodized - LT660
Product Description
Staging a high-performance red dot optic on your primary defense rifle requires a modular interface that guarantees absolute zero retention and instant quick-detach capabilities. Cheap skeletonized mounts or soft pot-metal clamps can warp under heavy weapon impacts, losing your red dot tracking alignment and causing your point-of-impact to drift downrange. The **LaRue Tactical® LT660 QD Micro Mount (LT660)** completely flattens these field vulnerabilities, offering a legendary, combat-proven weapon attachment block cut from a solid unibody block of aircraft alloy.
Proudly engineered, multi-axis CNC-machined, and performance-hardened in Leander, Texas, this specialized tall optical riser is configured specifically to establish a clean **Lower 1/3 Co-Witness height profile**. This centers your red dot clear above standard iron sights while keeping them visible in the lower third window for emergency back-up work. Machined from a single block of **high-tensile structural aluminum billet**, the mount features LaRue's patented **Speed Lever QD locking cam**. This locking arm tightens directly onto your receiver with thousands of pounds of pressure, eliminating the need for thumb screws. The cam mechanism is precision-radiused to ensure that if you need to strip the optic off your weapon in the field, it will click right back onto your rail with true return-to-zero tracking perfection.
Finished in an incredibly resilient, non-reflective Type III hardcoat anodized jacket and arriving with mounting hardware, thread locker, and adjustment tools, this premium armorer upgrade maximizes target tracking right on your workbench.
*Armorer Bench Notes & Real-World Optical Staging Guidance: The LaRue Tactical LT660 mount kit arrives ready for installation with the bare aluminum mount structure, the integrated quick-detach Speed Lever assembly, 4x flathead optical mounting screws, a vial of high-strength thread locker, and a custom LaRue hex adjustment tool wrench. PROPRIETARY MICRO FOOTPRINT INTERFACE FITMENT MATRIX: This specialized tall mount is engineered natively, strictly, and cross-compatibly to receive **micro red dot sights adhering to the standardized Aimpoint® Micro footprint**. *Co-Dependent Model Checklist:* It perfectly anchors the **Aimpoint Micro T-1, T-2, H-1, H-2, CompM5, CompM5s, CompM5b, Holosun® 403/503/515 configurations, and Sig Sauer® Romeo4/Romeo5 models** on your bench. System Sizing Exclusions: This model features the tall profile optimized for standard flat-top AR-15 / M16 / M4 upper receivers; use the shorter LT661 or specialized LT660HK variants if staging optics onto high-profile piston handguards or shotguns. Armorer Workbench Assembly Sequence: 1. Visually and physically confirm your rifle is fully unloaded, magazines are separated, and the workspace is completely safe. 2. Place your Aimpoint Micro optic upside down on a padded bench block, cleaning out the four threaded bottom base pockets. 3. Set the LT660 deck squarely over the optic base, align the four screw holes, apply a pin-head droplet of blue thread locker to each screw, and torque in a cross-pattern to exactly **12 inch-pounds (in-lbs)**. *Critical Tension Warning:* Over-tightening base screws can permanently strip the aluminum threads out of your optic housing. 4. Open the mount's Speed Lever arm, snap the base clamp onto your receiver rail at your preferred eye-relief index point, and flip the lever closed downrange to lock it firmly home.*
