You can align the holes using a guide (for lack of a better word) and then tap the pin in a little at a time with a small hammer/mallet. Do you have a gunsmiths block? Those are handy to have around. I think a little gun oil can help but also might make it slippery to handle.

PS: Make sure the tube is oriented correctly before you pin it. The block sits lower than the upper receiver , therefor the tube steps down into the block from the receiver.
