No cutting on my Russian.
I even managed to save the takedown lever from its date with a dremel.
I used vise grips and grabbed the pin and rotated it... titty-twister style. That loosened it up a lot, and helped me see where the pin was located from the backside. Was able to easily punch it out after that. A bit of marring from the grips, but no biggy.
I also installed a thin front post. I was a little bit miffed that I had to file the flats down for my front sight tool to work on it. Was a little thicker on the flats than the original Russian front post.
