Maintenance Tips

• Clean lenses with care: Use a microfiber cloth and lens-safe solution only. Fully multi‑coated lenses and ArmorTek coating protect clarity but require gentle cleaning.
• Keep lens covers on: Protect the 50mm objective from dust, scratches, and debris during transport and storage.
• Avoid touching glass: Fingerprints reduce brightness and can degrade coatings over time.
• Check turret & zero-stop system: Ensure the exposed locking elevation turret and RevStop zero system remain smooth and accurate for consistent tracking.
• Verify mounting stability: The 30mm tube must stay properly torqued to maintain zero and long-range precision.
• Maintain battery (illumination): Replace CR2032 battery when needed to keep the illuminated VMR-4 reticle visible in low light.
• Store in dry conditions: Argon-filled and fogproof, but prolonged moisture exposure can still impact seals over time.
• Wipe exterior after use: Clean aluminum body to remove dirt, oil, and moisture for long-term durability.
• Check parallax & focus: Side parallax (20 yards to infinity) should be adjusted regularly for sharp long-range performance.
• Avoid extreme environments: Excessive heat, shock, or prolonged sun exposure can affect internal components and precision.
