The LARUE TACTICAL LT849 MRO Cantilevered QD Mount provides a forward-arch design that sits over the receiver junctions to maximize flat-top space behind the optic, enabling optimal room for accessories and a clean, unobstructed viewing area. This 1/3 co-witness height is compatible with Iron Sights on M4 Carbine and AR-15 flattop platforms, delivering reliable aiming alignment without sacrificing speed or precision. Precision-machined from bar-stock aluminum and finished in matte black anodize, it offers a durable, non-reflective surface that resists wear and corrosion in rugged field conditions. The LaRue Speed Lever locking mechanism ensures outstanding return to zero, allowing the optic to be removed and reinstalled without compromising zero, so you can swap optics quickly in varying field scenarios. Built to the exacting standards associated with LaRue mounts, this cantilever design supports repeatable performance under recoil while maintaining solid mounting integrity. Ideal for shooters seeking a rigid, lightweight, and easy-to-use mounting solution that preserves optic position and sighting alignment across demanding shooting applications.
