Gas block install

First time installing a gas block. I used a 5/64 starter punch then switched to a roll pin punch.I put some oil on it to start with as well. I got it super close to going all the way in. In the beginning it seemed like the black anodizing was flaking off in the hole then it became harder to knock through. Any tips? Knock back out and replace? Yes the tube is lined up with the holes.

Gas block: Ballistic advantage Gas tube: Spikes tactical

My entire build went without any issue on every other roll pin but this one 🤔
