Don’t Get Caught Without It!
If your firearm has any type of screw that can be removed (on grips, backup iron sights, optics & mounts, weapons lights, etc.) then you must use Loctite threadlocker.
Over the years I have witnessed shooters at the range suffer as their shot groups got bigger and bigger, and only after many expensive and frustrating rounds later realize that their optics was no longer firmly mounted on the weapon. Over time the weapon’s recoil had loosened the screws of the mounts to the point that the scope could no longer hold zero. I have also seen many accessories such as backup iron sights (BUIS), grips, rails, light, and lasers start to wiggle loose. There is a simple and inexpensive solution to this problem. Loctite Threadlocker.
Whenever you add accessories to a firearm that involve screws you should always be sure to use a dot of Loctite “Blue 242” threadlocker on the threads of the screws. If you don’t then the screws will eventually start to wiggle loose over time. Don’t even bother mounting an item on a firearm if you aren’t going to Loctite the threads. It won’t stay on.
