A little help needed removing a very difficult to remove O Ring

Hi everyone! A report on how I tackled the very stiff O-ring inside the receiver bore. I blew with high air pressure inside the bore first, but since the O-ring was very stiff, it did not budge. I dropped some acetone on one side of the O-ring a number of times and break cleaner on another section. Neither made a great difference. Eventually, as Stubbers had suggested, I used a needle to melt away part of the O-ring. The needle was not doing a lot of melting as as soon as it touched the O-ring, it started cooling quickly. Then I took a very simple soldering iron with a needle nose tip, made the tip more slender and then heated and bent the tip and then using the sustained heat I managed to melt the O-ring on one section and melted a second section a quarter of the way on the O-ring and eventually that section came off and then using a plastic pick I had made with the body of a pen with a bent tip, I scraped the O-ring off completely.

Can get the same o-ring out. It's looks particularly deterated, is there something you can apply to melt the o--ring with out hurting the aluminum

No no no no no and.......NO. Dental pick, a SHARP brass pick or a needle, you're just trying to get it started out of that Y^%$ groove, then use some long self closing tweezers. https://www.amazon.com/gp/product/B073SJD7L5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 to pull it out. The key is patience, lots of it.

A large needle is a much better tool. As described above, stab the o-ring, and pry/roll it out of the groove.
