The Trijicon R Cap with Q-Loc Mount System is a 34mm accessory ring cap engineered to work seamlessly with Trijicon's Q-LOC and Slimline variable power scope mounts. If you're running a multi-optic setup or need to swap components on your magnified optic platform, this cap lets you attach red dot sights or Picatinny rail-mounted accessories at either 12 o'clock or 45-degree positions—giving you the flexibility to build out a complete optics solution without starting from scratch.
Built from Mil-Spec 6061-T6 aluminum and finished in matte black anodize, this cap is lightweight yet rugged enough to handle field use. It's designed as a direct replacement for the front or rear caps that ship with Q-LOC mounts, so if you've lost one or need a spare to experiment with different configurations, this is the straightforward answer. The three mounting locations mean you have real options for how you stack your glass and accessories without forcing a compromise on sight picture or ergonomics.
Whether you're a precision rifle shooter building a dedicated optics platform, a tactical rifle owner testing multiple sight solutions, or an overlander who wants redundancy in your aiming systems, this cap removes the barrier to experimenting with Trijicon's modular mount ecosystem. It ships with four screws and a hex key, so you can get it mounted immediately.
