Doing an ultra light build and I need to mark the center of the gas tube hole. How would you go about doing this? #14 drill bit already in hand.  don't want to send it to Adco ($50.00 + shipping)

If you don't have the tools and skills to make it exact, it's just a clearance hole anyway.  Use a milspec barrel nut and a center punch to mark it.  Drill away.  Unless you have zero patience and couldn't pass a background check for a hammer, it should be a 10 minute job.

wouldn't a transfer punch be better?

No. He has a 9mm upper (no FA, no deflector) that wants to use on a 556, is he needs to drill the gas tube port.

OP, I just sent mine to ADCO and it came out good. 50 bucks to make sure it's done right is worth it to me.
