07 pmr stripped plastic bolt cap need help ASAP

Don’t know what to do to get it out wonder if there is any safe way of doing it to not damage the actual bolt and gun itself planning on getting aluminum back cap but need to remove the stripped Oem plastic one first.

Two goals here...
- get purchase on it so you can unscrew it, and perhaps
- reduce how tight it is so it unscrews easier

I've usually been able to get a flathead screwdriver or some other tool jammed into one to turn it, knowing the back cap may be destroyed. I've literally tapped a tool in with a hammer (softly) My backup plan which I've not had to do yet, was cut across the cap and force a coin into the cut.

As for loosening --- 2 possible options:
- in theory freezing will shrink everything. You can throw it in freezer for a day
- a penetrating oil can help. PB blast or such. Give it time. Waiting a day here, really does help.
