Rusan Weaver Rings with Screw Fixation (40 mm | H11)

For the serious precision marksman equipping optics with extra-large main tubes, the decision to buy Rusan Weaver Rings with Screw Fixation ensures unyielding stability and deliberate mounting control. These Croatian-engineered 40 mm rings, CNC-machined with a tailored 11 mm height profile (product code 050-40-11-V), deliver unwavering support under the most punishing recoil and field conditions.

Engineered for Big-Tube Optics

At 11 mm above the rail, these rings clear heavy 50–60 mm objective lenses while keeping the optical centerline close to the bore axis. The result is minimal cheek-weld shift, simplified ballistic compensation, and a natural sight picture for long-range engagements.

Monolithic Steel Construction

• Single-Billet CNC Machining: Each ring starts as a solid block of premium tool-steel. Advanced multi-axis milling ensures perfect concentricity and eliminates stress risers from cast or welded designs.

• Durable Black-Oxide Finish: Provides robust corrosion resistance and wear protection in harsh environments.

• 15 mm Tube Contact Width: Broad surface area around the 40 mm tube for even clamping pressure and zero creep.

Rock-Solid Screw Fixation

• V-Series Precision Screws: Torx T15 fasteners allow controlled torque application—lock your scope in place with repeatable consistency and zero guesswork.

• Integral 3.6 mm Recoil Lug: Machined from the same billet, this lug seats directly into rail slots to prevent any forward or rearward movement under heavy magnum recoil.

• Uniform Clamping Force: Matched upper and lower halves apply even pressure, eliminating stress points that could deform your scope tube.

Installation Protocol

1. Clean the Rail: Remove all debris and oil from rail surfaces.

2. Position the Rings: Align rings at the proper spacing; ensure recoil lugs fully engage rail slots.

3. Torque Base Screws: Tighten bottom screws to 2.0–2.5 Nm.

4. Set the Scope: Place your scope in the lower halves; verify eye-relief and reticle centering.

5. Secure Upper Halves: Install top halves and torque Torx T15 screws in an alternating pattern to 1.8–2.0 Nm.

This systematic approach guarantees uniform clamp pressure, maintains optical integrity, and preserves zero even after hundreds of heavy-recoil shots.
