ANNEX Arca Rail – Q-Sert Compatible (R-LOCK® Licensed)

Purpose-Built Arca Rail for the Q FIX and Q-Sert Platforms

This isn’t an adapter — it’s a dedicated Arca-Swiss rail, precision-machined to bolt directly into your Q-Sert slots, giving your Q FIX or other Q-Sert-compatible rifles instant tripod versatility. If you're running RRS, Leofoto, or any Arca-style tripod system, this is the no-nonsense solution that locks down tight, doesn’t budge, and adds no excess weight.

Built to Really Right Stuff’s official ARCA-SWISS standard and licensed for use with R-LOCK®, this rail integrates seamlessly with premium tripod heads and clamp systems.

Why We Like It

This is the cleanest and most reliable Arca mounting solution we’ve found for the Q FIX. It mounts directly, weighs almost nothing, and locks into RRS heads with no fuss. If you’re running tripods in the field, especially with ball heads or pig saddles, this is the rail we’d use every time.
