Drilling an AR barrel for a shight block.

I'm building an AR with a Faxon on barrel. I want a sight block on it. The barrel did not come predrilled.

Anyone drilled and reamed an AR barrel before? How did you manage to not mess it up? Did you create/buy a jig.

I've found a video on YouTube, and the way the guy did the work included a bunch blue painters tape to align the parts. Looked risky to me.

Jig only.... or you can do it the Dirty Harry way....
“ you’ve got to ask yourself one question...do I feel lucky?”

$250 for a jig! I guess it is off to a gun store.
