Stuck rail mounting screws help 20 MOA install

Two screws came out they were darn tight for sure and had a white thread lock residue on them. I broke off a T15 torques bit trying to get out the other 2 screws at that point. I was afraid to go further.
The rail has 4 screws and 2 Dow pins holding it in place.
Suggestions please…
Thanks all

Heat the screw heads a bit with a heat gun. That should help break them loose.

I've pulled a couple rails off of original CTRs that were epoxied on to boot. They were a pain in the ***.

Soldering Iron in the screw head until you see a little smoke from the locker

I will reply back when I get it off and what worked!
I was a r&d job shop machinist for years before bcc's.
The two things I learned quick was.
Ask for help.
Know when to stop and re-evaluate a situation.

I wish you luck with that because my tac A1 rail is also glued on to the receiver so I bought a spur 20moa mount instead I figured it was great foundation

I just finished drilling out some screws on a set of rings attached to a pic rail. One of the screws just would not release and was completely fused. It's a frustrating thing to happen for sure and expensive to boot. At least this was on the the rings instead of the rail into the receiver.

Clean the locktite off and put the other screws back in, MAKE THEM TIGHT!!! this will make it easier to get the last 2 screws out

If the rail is also glued, set a hot clothes iron on the top for a bit. The glue will give up.

Most types of thread locker break down at 140℉. A strong heat gun, soldering gun should break it down and make for easier removal.
Loktite 243 works well, and uses the same force to remove as was used when installed. So far I have not had any loosen that I did not take out on my own.
If you know a machinist, the machinist can grind a drill bit that will chip the hardened screws out. Be sure to use a safe vice and precision drill press for the job.
