I have a Noveske Lower and a Daniels Defense Forged Upper. They pair together nicely, minus the somewhat shiny Noveske Finish.

But when I actually go to snap my Pivot Pin in, it is waaaay tight. Even with oil it have to force it through the Upper Hole. And once its through, getting it back out requires a punch and a hammer.


I imagine I'm going to have to make the hole a little bigger on the DD Upper. Has anyone done this? Any 'fantastic tool' that could make it easier? I've never had an issue with a Pin not fitting good, so this is all new to me.
