🔵 Opticlocker 243 Blue Thread Locker – 10ML Bottle

Keep your red dot sight screws locked down and mission-ready — no stripping, no loosening, no failures.

If you've ever had an optic shift zero because the screws backed out under recoil, you already know why thread locker matters. The Opticlocker 243 by C&H Precision is a medium-strength blue threadlocker designed specifically for firearms and optics mounting.

This is your Loctite 243 alternative — optimized for mounting red dots, plates, and other pistol or rifle accessories. It's strong enough to resist vibration and recoil, yet removable with standard tools when you need to swap optics or adjust your setup.
