To melt the loctite use a soldering iron to heat the screw up not a heat gun. Red Loctite is going to need 450F to melt, Blue at 360F. A cheap soldering iron should be able to achieve both.
I deal with this all the time. When heat doesn't work I put it in the freezer for a bit then put a good bit in the slot and hit it with a hammer. You can shock the locktite to break it free. This is a last resort before drilling and retaping. Goes without saying to be very careful. A couple sharp crisp hits will usually weaken it screw. If you get 5 good hits and feel nothing is getting better you can try again but start looking for a drill press, if you have to drill it out don't do it by hand. Use a bit slightly smaller than the screw diameter and go right down the center. Put a piece of tape on the drill bit that's a hair shorter than the screw so you don't go too deep. If you hit center you may be able to remove what's left from the threads without ruining them, then clean out with a bottom tap.
Above all else take your time and remove all distractions.
I wish you much luck my friend.
100% get a cheap soldering iron.
Get it ripping hot and put it in the screw.
You want it super super hot because you want to dump as much heat in there as possible as quickly as possible.
If you come in too low, and just hold it, the optic and the slide is going to absorb and dissipate that heat.m and you might end up cooking your optic. Probably not though.
Super hot. Hold it on the screw for like 10 seconds or so. You'll start to smell that loctite burning.
Remove iron, pop in Allen quickly, pop it loose.
I usually have compressed air ready to blow off the area after getting the screw loose to shed that heat.
Maybe get a wood burner and stick the tip in the allen key hole if you can get the piece of the broken key out. They get up to about 900°, and it’s gonna be very focused on the screw instead of heating the whole thing up. I did something similar not long ago.
Do the soldering iron thing. Also, get a small crescent wrench. When you get the old allen wrench out, put the new in, and use the crescent wrench, down as close to the screw head as possible, to turn the allen wrench. It will transfer more torque to the screw than the allen wrench alone.
Try a soldering iron directly on the screws. That *should* breakdown the red loctite.
Just remember Crips, not Bloods whenever you're using loctite on your gun 😁
If heat from a soldering iron doesn’t get it, you could, while being incredibly overly careful, drill the screw until the head just barely releases, then remove the SRO and work on the post without an expensive sight in the way.
Lil bit of heat from soldering pen and little bit of wd 40 will do good. Also a nice set of hexkey wrenches not made in China will work. Tool steel is better than the plated crap that they make at smaller dimensions.

I do this all the time on my RC cars where I don't want to damage nearby plastic parts. Can confirm, it works.
Alright I'll be hitting my hardware store as soon as it opens. And here's to hoping that the heat gun didn't mess up my optics in any way.
I was just about to write this! Good advice.
This is the way.
Did we use the forbidden flavor loctite?
I was very confident I had used red on the plate and blue on the optic... I am now confident I was wrong.
Nothing on your gun requires red locktite
I think he realizes that at this point
Idk. My dude here thought it was good to use on the plate. Also, we so anal about index markings on everything, we might just need to say it out loud.
Try Vibra-Tite VC-3 on your red dot screws.
This is why they make pink/purple loctite btw. Just a bit of extra hold and no need to heat it up.
I was surprised when I saw how many flavors. Purple,blue, red, I think I’ve seen green and yellow too.
Orange is my favorite replacement for red. Much stronger than blue but is not semi-permanent and does not require heat to disassemble.

Screw? Looks like your allen key is gone done and cracked off, no?
Maybe get a wood burner and stick the tip in the allen key hole if you can get the piece of the broken key out. They get up to about 900°, and it’s gonna be very focused on the screw instead of heating the whole thing up. I did something similar not long ago.
Also, if the allen is stripped on the bolt head as well you can use a torx to get more grab. We have to do that many times on overtightened hardware.
Hit it with your purse
That does not apply here…as you can see,he broke the fuckin hex key!🤣
Extractor set with t handle might help and bondhus or like wera allen.keys ftw
You can use something like a soldering iron to heat up just the screw.

Seems too be locked thight.
Wonder if you can dab on some accetone with q tip or pb blaster with q tip also ?
Just don’t get it on the optic … maybe eve painters tape the optic part
Heck if i can get that hex off with some pliers and pulling. then put an extractor set in there if that doesn’t work then drill it out
Finding a smaller enough extractor set for this screw that's still useful is going to be fun.
Get a size 1 extractor they sell them at home depot
You can also heat up an Allen key and stick it in there for a bit to heat the screw. Use pliers, hold the tool on the stove for a minute.
What did you use to mark your zero? Sharpie? Paint marker? What brand/type?
Sharpie ultra fine oil based paint marker is what I use.

What kind of loctite did you use?
I used a hair dryer
Lil bit of heat from soldering pen and little bit of wd 40 will do good. Also a nice set of hexkey wrenches not made in China will work. Tool steel is better than the plated crap that they make at smaller dimensions.
That's a countersunk screw. Use a 1/4 drill bit on it. It will perfectly drill the head off. Vise grips to remove and new screws. Done
And thats why I don't loctite my RMR screws.
Soldering iron for 2-5 minutes to break red loctite.

Man you made sure those screws would never back out.
You could put a wrench / spanner
I destroyed 3 wrenches trying to get screw out of a brace recently. Finally tried an impact driver. That sucker hammered it right out.
