SAUER S404 UNIVERSAL TOOL

The SAUER S404 UNIVERSAL TOOL is a purpose‑built, compact maintenance and setup tool made to the needs of S404 owners, armourers and gunsmiths. Engineered to Parker‑grade tolerances and finished for corrosion resistance, the tool bundles the common drivers and wrenches required for routine S404 work — from action and stock screws to scope mount torque settings and sight adjustments. Its layout and bit selection match Sauer factory fasteners, so you can carry one rugged tool for if‑and‑when you need to adjust bedding screws, tighten mounts, change stocks or perform on‑gun checks in the field.
