The co-witnessing sights thread got me thinking...

The only time I have ever used Loctite on optics is when I have used cheap mounts. When I used quality mounts, proper torque was all that was used. I was taught this when working at a gun counter many years ago. The Leupold rep taught us how to properly install their scopes and mounts.

What say you? Loctite or no?

I don't use it on sights even the cheap mount I got with my Primary Arms Micro Dot. If I found that screws were working themselves out I would not hesitate to use it but have not had the need.

I do use it often on grip screws and set screws on handgun sights. There I often use purple because of the size of the threads. It is enough to hold but still break without too much torque.

I never ever use the red type but have used a small dab of blue on some small hex head or torque screws

Bigger screws would get lock washers if needed.

If there's a screw I use it. I'd rather be safe then sorry, different colors for different applications of course.

This. I use the blue loctite stick (not the fluid, the stick is thicker) on almost everything, because why not? Combine it with a Wheeler FAT torque wrench screwdriver and you're never going to go wrong.

Fat Wrench is your friend with quality hardware and manufacture's torque specs. Not too worried about my Badger Ordnance hardware flying off the rifle absent Loctite. Poor quality hardware can be a mixed bag. Sometimes it's safer to use Loctite rather than for some folks to shear off a screw with little effort or suffer chronic loosening.

Then there's the enigma of a steel rear sight on one of my ARs. It will work loose no matter what absent Loctite.

My Model 632-1 has such a sharp little kick that it would loosen the front mounting screw on the rear sight after about 25 or 30 rounds. A tiny drop of blue loctite seems to have cured the problem.

That happens to me on this gun.

Never seen the stick. Might have to pick one up.

I keep a bottle of red, blue, and the low strength some say is purple and others call pink. They all have a purpose. I don't like the stick type as I feel the liquid works much better. All the scope mounts I've ever installed got just a tiny dab of blue to be positive they never vibrate loose but are still easily removed if the need arises. One thing to keep in mind is that Loctite can damage some plastics so I never use it on anything that screws into plastic.

Kinda like a tube of chapstick.
