I work in the industry and cannot stress enough how important a proper gun build is for safety reasons. Screw You Tube!

Bolshevik Communist Google ruins everything they touch. Anyone that still uses Google for ANYTHING needs a slap upside their empty head.

I may be wrong, but when I put a gas tube in a gas block, I just use a pair of channel locks and squeeze it in there, then tap it once or twice with a punch. When I put the gas block on, I put it on up-side-down first, because that front set screw hole mates exactly with the gas port. I use a feeler gage to determine precisely how far, if any, the gas block should be backed away from that lip on the barrel. Once I have that, I put the barrel on the receiver, match it up with my line (like you have), use the feeler gage to set it, then tighten her up with some thread locker. If you do a lot of those, there's a little jig you can buy to line you up correctly for dimpling your barrel.
