Rusan Weaver Rings with Screw Fixation (40 mm | H8)

For the precision shooter mounting a 40 mm main tube who demands rock-solid security and a low-profile sight line, choosing to buy Rusan Weaver Rings with Screw Fixation is an investment in Croatian-engineered durability and methodical mounting control. These rings, CNC-machined from a single billet of high-grade steel and finished in corrosion-resistant black oxide, feature an 8 mm height (product code 050-40-8-V) for minimal offset and natural head position.

Balanced Height for Large Objectives

At 8 mm above the rail, these rings clear medium-to-large objective lenses (44 – 50 mm) while keeping the optic’s centerline close to the bore axis. The result is reduced cheek-weld movement, simpler hold-over calculations, and a more comfortable, repeatable sight picture.

Precision Steel Integrity

• Monolithic billet construction—eliminates welds or joints that introduce flex under recoil.

• Uniform 15 mm contact width—distributes clamp force evenly around the 40 mm tube.

• Black-oxide finish—resists corrosion in field conditions without flaking or peeling.

Secure Screw-Fix Attachment

• V-series screw system—Torx T15 fasteners deliver measured, torque-controlled tightening for a consistent clamp every time.

• Integral 3.6 mm recoil lug—machined from the ring body itself, seating firmly in rail slots to prevent any fore-aft shift under heavy magnum recoil.

• Matched upper/lower halves—engineered to clamp true, preserving zero and protecting scope tube integrity.

Installation Guidelines

1. Thoroughly clean rail surfaces to remove debris and oil.

2. Position rings to achieve desired eye relief; ensure lugs fully seat in rail slots.

3. Torque base screws to 2.0 – 2.5 Nm.

4. Place scope in lower halves, verify eye relief and reticle centering.

5. Secure upper halves with Torx T15 screws in an alternating pattern to 1.8 – 2.0 Nm.

Following this protocol ensures uniform clamping force, protects your optic tube from stress, and maintains zero shot after shot.
