I noticed that the set side (the inside part) were not all uniform in their set depth. I then looked up the cherrymaj spec sheet:
I may have also found something else. But on page 18 is shows what they should look like. A lot of mine 25 % were not set completely so that the safety lock was engaged. I drill out and they were super simple to get out. I assume that if they had been set correctly, then the removal process would have been more difficult. I could be wrong.
I might have taken pics. If so I will post later.
I used a pneumatic puller to set. But not one made specifically for cherrymax.
