Rifle scope mount screws are arguably the most critical fasteners for firearm accuracy. They are instantly subjected to extreme recoil shock (a massive impulse load), continuous high-frequency vibration during transport, and the absolute necessity of maintaining perfect alignment (zero). A loosened screw means a dangerous loss of zero, compromised accuracy, and potential damage to expensive optics.
Don’t let recoil or vibration compromise your accuracy; secure your mounts with a proven chemical lock.
INCURE Re-Lok™ B43 Blue Standard Duty Threadlocking Adhesive
For securing scope mounting hardware—a critical application that still requires occasional adjustment—a balance between security and serviceability is required. The INCURE Re-Lok™ B43 Blue is the industry standard, providing superior shock and vibration resistance that ensures the mount holds zero, yet allows for easy disassembly with standard hand tools.
| Feature & Benefit | Technical Insight for Scope Mounts | Conversion Value |
| Medium Strength (Standard Duty) | Provides a secure lock for fasteners up to M20 (ideal for common optics hardware), neutralizing shock, while still allowing for removal with hand tools. | Precision & Service: Lock down the zero against recoil, but permit scope swaps and adjustments easily. |
| High Shock Resistance | Cures into a solid plastic that fills the microscopic gaps, effectively damping the massive, instantaneous impulse load generated by firing the weapon. | Maintain Zero: Eliminate rotational creep and thread play caused by recoil, ensuring consistent point-of-impact. |
| Temperature Stability | Maintains its strength and integrity across common shooting temperatures, ensuring reliability from cold ranges to hot environments. | All-Weather Accuracy: The lock remains robust regardless of external conditions. |
| Controlled Lubricity | Ensures consistent clamp loads during tightening, which is critical for maximizing grip without over-torquing and damaging the scope tube or receiver threads. | Protect the Investment: Torque your fasteners accurately for maximum security without damaging high-value components. |
Application Steps: Securing Scope Mounts for Maximum Accuracy
Preparation (Mandatory): Clean the threads of both the screws and the receiving threads (receiver or base) thoroughly. Use a degreasing solvent (like isopropanol or acetone) to remove all oil, ensuring surfaces are clean and dry. This is vital for accuracy.
Application: Apply a single, small drop of Re-Lok™ B43 Blue to the middle threads of the mounting screws (base-to-receiver and rings-to-base).
Assembly: Install the scope mount and rings. Torque all fasteners to the manufacturer’s specified value (typically very specific and critical for optics). Follow the recommended sequence (often crisscross for ring caps).
Curing Time (Critical): Allow a minimum of 24 hours for the adhesive to achieve its maximum strength and anti-shock resistance. Do not fire the weapon until the full cure time is complete.
Stop risking dangerous loss of zero and secure your critical optics components with dependable chemical integrity.
