RedDot Torque

[Dog214]

I’m trying to see what everybody else may be using regarding a red dot on a heavy magnum revolver specifically a 500 Smith & Wesson. I’ve tried to follow the torque recommendations for fastening it to the Picatinny rail. Following the manufacturer recommendations puts me between 15 and 25 pounds of torque depending on which brand. I have done that and even included blue Loctite each time within six or seven rounds the red dot site loosens any suggestions?

Did you use Loctite primer? {Toluene can substitute} really increases the “grab” factor and the next step up from the blue is the red for a nearly un-removable lockdown..
I even have some of their Sleeve Retainer {part # 27-26} that also makes for a nearly impossible to break loose retention.

I would highly recommend NOT using the red Loctite!!

If you ever want to take it off, you need heat. 500°f or higher.

Also, you don't really need a "primer" for Loctite.
And I really wouldn't use Toluene!
Toluene is an adhesive remover/paint stripper.

Essentially, you need to remove any dirt and oils before applying Loctite. Denatured alcohol will work fine and you don't have to worry about it taking off the finish.

In a pinch, spray some starting fluid in a paper towel.
OUTSIDE!!! Lol

You just need a cleaner that doesn't have any oils in it.

So I think my problem has been the fact that the red dot(s) have been mounted with see through mounts so I could still use the iron sights. I did use loctite and it was definitely tight. I was gonna move it forward after installing it and broke the T-10 tip off trying. Unfortunately after shooting it loosened. The only other variable now is the height. I am now mounted with a flat plate to the rail no more see through mount. I will be heading back to the range Tuesday to give it a whirl. .
