Trijicon ring mounts with Q-LOC technology feature a 35mm tube, designed to maintain a low-profile ideal for hunting and long-range precision rifle applications. Constructed from Mil-Spec 6061-T6 aluminum, these mounts are both lightweight and robust, with an Easy-to-use, one-handed, tool-less mounting system. The spring-loaded mechanism ensures constant retention and zero retention, even when knobs are not fully tightened. These mounts offer superior return-to-zero performance and are compatible with any Mil-Spec or NATO picatinny rail. Specifically engineered for variable power optics, they provide a secure platform for mounting Trijicon variable power optics with objective lenses up to 40mm on any weapon equipped with a full picatinny rail.
