Green threadlocker on a dovetail front sight?

[gunsrfun1]

I just installed a Williams Firesight front sight in my Marlin 1894. It's a dovetail fit. It seems pretty tight, but I thought I would put some green threadlocker/Loctite on each side of the dovetail and let it seep in. It's considered a "wicking" threadlocker by the various manufacturers.
My question is, should I ever want to remove the front sight, will I be able to drift it out without heating it up?
All the info on the green threadlocker (regardless of brand) classifies it as "medium to high" strength, and removable "by hand tools or heat." So I am a bit confused.
Granted, the amount that seeps in will probably be tiny anyway. But I don't want a "permanent" bond where I have to heat everything up to drift it out. I just want to be able to use the same sight pusher to remove it as I did to install it, should the need arise.
Would you say I am OK in using the green threadlocker, or should I leave well enough alone? Or maybe use some blue and hope that enough seeps in to do the job?
Thanks

Well, is the sight okay and positioned where you want it? If so, what’s done is done. I wouldn’t worry about it.

Supposedly one could use Loctite Cleanup Solvent. I also read that several applications of boiling water would work as well as using a heat gun. I have no experience with Loctite Green so I really do not know the best solution.

LOCTITE® Green Threadlocker is recommended for locking preassembled fasteners, e.g. electrical connectors and set screws. The product is categorized as medium-to-high-strength for wicking. It is also available in a liquid form, cures in 24 hours and can be removed with heat and hand tools.

The hot tip of a soldering iron is enough heat. Just takes a while.

leave well enough alone

To make tighter, if needed, i put a shim under the sight. I use aluminum foil. If it moves first.

Nail polish works also.

I just used blue loctite on a 1911 rear sight, and then needed to adjust it. Took a few good taps with a brass punch, but it came free. I think you'd be fine with green

With different brands color means different things, with some it doesn’t mean much at all (more than one formula with the same color, 82 different versions of loctite for example https://www.henkel-adhesives.com/us...2798e36db1f3ab7b21e7333ef79339689f7895.page=9). “Wicking” is for parts already assembled but if you have oiled the rifle since installation, it is also “wicking” and will make the thread locker less useful.

I am the type that if it felt good when I installed it, would let it go. Even with pistol sights, I have had more that didn’t move without thread locker than ones the owner couldn’t move when they used thread locker and subsequently needed to move them.

If I were so inclined to use something, I would start at the lowest strength I could find.

This might be worth looking at.

Thank you all. This was very helpful. I did forget that I did put some grease in the dovetail before I installed the sight. So as jmorris has pointed out, that will reduce the effectiveness of the loctite.
I also remembered that in the past, I did put some nail polish on the edges of a sight, just as insurance, as 243win has pointed out. So I think I am going to start with that; just put some nail polish on both sides of the sight and let it "wick" into the edge of the dovetail a bit. I don't want to be in the position of not being able to remove the sight if need be.
Obviously if I notice that it is loose or moves after shooting it, I'll reconsider.
Thanks again.

Yup. There is a thin shim under the rear sight of my Henry.

Shin under, peen the dovetail or the slot, or add a set screw. I would not add threadlocker.

Something else to consider is Dykem Cross Check. It's not a super-glue or anaerobic adhesive, but more of an indicator like nail polish. It won't secure the part any better, but it will make it obvious when the part has been bumped or loosened. I would be more inclined to put it on the heads of sight screws than on a dovetail, but it would work there too. A contrasting (silver or black) Sharpie mark can work too, but those marks rub off more easily. Again, the idea is not to lock the part in place, but to make it obvious at a glance if the part has moved at all.
