Installed my front trunnion today after I installed it I noticed that one side isn’t flush with the receiver and is sticking out. Is this bad? should I remove the rivets and some how drill new holes or should I start with a whole new receiver? Also how do this rivets look?

It depends. If everything mocks up and fits, then it is probably not a problem. How does your handguard look? It looks like you build like me. I install the trunnion and then headslace the barrel. I hate pressing out a headspaced barrel if I don't have to.

The rivets look fine. The thing to check is if there is a gap between the rivet head and receiver. That means you didn't get the rivet pushed all of the way in flush. That could be a problem and if any are not flush with the receiver, I would redo them.

Front four are flush rear two are not

Here it is with the hand guard mocked up. Right side is the one that isn’t flush

Unfortunately your picture isn't showing for me.
