I'm at a loss here.. Anyone else had this problem??
I just did my friends and I got lucky they punched right out. I grinded them down flat to the same level as the sight base, and got the right size punch, and it worked. Did not put a nick on the barrel.

I just grinded of one side and I can barely make out where the stem of the rivet was. I used a punch half the diameter of the rivet head, hoping it would fit. I got lucky and it popped out. I have never broken down a front sight base like that, I can't believe they drill out the barrel for the rivets. That's why I think they are garbage. I have only built with free float quad rails and rail mounted sights. Can you even make out where the grinded of stems are?

No. It's the damnedest thing. I even tried a titanium bit on a high speed dremel and it would just spin on the dimple I made, didn't even bite into it.

I'm at a complete loss for what to do...

You really need a hydraulic or pneumatic press, but since you don't have access to one... If you are going to try to drill them out, you could try a diamond coated, glass and tile bit.

I couldn't change out the gas block on my Bushmaster AR-15 for the same reason. I took it to a gunsmith and he couldn't do it without a press. He said the barrel was coated after the block was installed and that coating is super strong. You have to break the seal of that coating around the rivet and it takes a lot of pressure to do it. I think it is manganese phosphate.
