Who This Is For

This ring cap is ideal for precision shooters and tactical operators running Trijicon Q-LOC or Slimline 34mm mounts who want to build out a full optics solution — pairing a magnified optic with an offset red dot or other Picatinny-compatible accessory — without adding unnecessary weight or bulk to their rifle platform.

Frequently Asked Questions

Which Trijicon mounts is this ring cap compatible with?

This 34mm ring cap is specifically designed to integrate with Trijicon Q-LOC and Slimline style variable power scope mounts. It is not intended for use with non-Trijicon rings or third-party 34mm mounts, as the attachment interface is proprietary to Trijicon's system. Always verify your current mount model before purchasing.

Can I mount a red dot sight directly to this ring cap?

Yes — the three mounting locations on this ring cap support the attachment of red dot sights or Picatinny rail mounting plates at either the 12 o'clock or 45-degree positions. This allows you to create an offset or co-witnessed optics configuration alongside your primary magnified optic, giving you fast close-range acquisition without removing your long-range scope.

Is this cap intended to replace a damaged cap, or can it be added as a new accessory position?

Both. While this ring cap is designed as a direct replacement for the front or rear cap included with Q-LOC style mounts, it also functions as an upgrade for shooters who want to add mounting real estate to an existing setup. If your current cap lacks the three-position accessory interface, swapping it for this cap opens up new configurations for offset red dots or lights.
