Trijicon Q-LOC Cantilever Mount, 30mm Tube, 1.59" Height, Black

The Trijicon Q-LOC Cantilever Mount is a 30mm tube scope ring engineered for hunters and precision shooters who demand low-profile mounting without sacrificing zero retention or reliability. Built around Trijicon's Q-LOC technology, this mount holds your optic steady and returns to zero reliably, even on hard-recoiling rifles used in hunting or long-range applications. The one-handed, tool-free mounting system means you can install or adjust your scope quickly in the field, while the spring-loaded design maintains constant tension on the ring caps—your scope stays put whether you're fully torqued down or running lighter specs.

Machined from 6061-T6 aluminum and mil-spec drop-tested, the Q-LOC mount delivers rugged durability in a lightweight package. The 1.59" height positions your optic just 1.59" above the Picatinny rail, keeping your sight picture low and your cheek weld natural—a critical advantage whether you're running a hunting rifle or a precision bolt gun. Its matte black anodized finish resists glare and corrosion, and the mount is compatible with any mil-spec or NATO Picatinny rail. Trijicon manufactures this mount in the USA, backing it with the quality control you expect from a company that builds both professional military optics and civilian hunting gear.

The Q-LOC system's spring-tension design is its real strength: it allows flexibility during installation but holds rock-solid during use. You can apply spring tension only (12–16 in./lbs) for a tool-free mount that won't shift, or tighten all the way to 44–66 in./lbs if you prefer maximum mechanical lock. Ring caps torque to 14–16 in./lbs. The mount accepts objectives up to 56mm, giving you room for larger bell optics without interference.
