The only thing I could add to Denny's post is at step 4, the point you're checking alignment of the gas tube, I've found it easier to check for proper alignment by using just the bolt carrier, no bolt or charging handle. Insert the carrier into the upper, tip the upper slightly and if the gas tube is correctly aligned, the carrier will slide completely home under its own weight. Any misalignment will stop the carrier.

That's what I did when I worked for brand X. The hole needn't be deep or centered just somewhat concentric with the outside of the punch. I used a broken 1/16" pin punch (cheapies they supplied us with there) that I ground the end flat on. Chucked up in a vice on standard drill press (too much trouble to set up a mill or lathe) and drilled it. The gas tube roll pin is the only one I feel the need to use it with. The rest start fine by hand or needle nose. The raised edges of the FSB always interfered with the needle nose before.
