The Trijicon Mount AC22081 Picatinny Rail for Short Accessory Ring Caps is the purpose-built accessory rail component designed to mount to the Accessory Ring Caps sold for Q-LOC style mounts — the factory-correct Picatinny rail plate that gives Q-LOC mount users the ability to add any standard Picatinny-compatible accessory, optic, or device directly to their existing scope ring cap system for a complete integrated solution in a single unified platform. The Picatinny Rail Mount AC22081 can be located at the 12 o'clock or either 45-degree position, depending on the specific accessory being mounted — the positioning flexibility that gives shooters the correct mounting location for the particular device or accessory they are adding to the ring cap system. The 12 o'clock position works naturally for accessories the shooter wants directly in line with the primary optic's sight picture, while the 45-degree positions provide fast offset access for close-range devices and accessories the shooter wants immediately accessible via a simple rifle roll. The Quick Release Mount AC22081 Picatinny rail is specifically designed to work with Trijicon Q-LOC and Slimline-style variable-power mounts and accessory ring caps — the factory-correct integration that creates a complete optics and accessory solution within the existing Trijicon mount system without any additional adapters or incompatible hardware. The Q-LOC system's innovative spring-loaded attachment mechanism allows easy mounting and unmounting without re-zeroing, one-handed operation, and multiple recoil lugs that ensure full rail engagement and secure retention during heavy, repeated recoil. The Trijicon Mount AC22081 Mil-Spec drop test rated 6061-T6 aluminum construction delivers the structural integrity that a ring cap-mounted Picatinny rail demands. The compact circular design reduces snag hazards, while precision-cut dimensions ensure compatibility with MIL-STD 1913 Picatinny rails, NATO rails, non-mil-spec rails, and even damaged rails. Features: Can be mounted/un-mounted without the need to re-zero the optic One-handed mounting Multiple recoil lugs for total rail engagement and superior resistance to recoil Compact circular design for reduced snag hazard Compatible with MIL-STD 1913 picatinny rails, NATO rails, non-mil spec rails, and even damaged rails Trijicon’s Q-LOC Quick Release Cantilever Mount offers a high degree of versatility to the most discerning users. It utilizes an innovative spring loaded attachment mechanism, allowing it to be easily mounted/un-mounted without the need to re-zero the optic. This proprietary design also allows for one-handed mounting, and multiple recoil lugs ensure total rail engagement as well as secure retention under heavy, repeated recoil. Other features of the Q-LOC mount include a compact circular design to reduce snag-hazards on loose clothing/equipment, and precision cut dimensions allows for compatibility on MIL-STD 1913 picatinny rails, NATO rails, non-mil spec rails, and even damaged rails.
