I stumbled across these gas port alignment pins while reading on another site (https://www.frfrogspad.com/index.htm). After watching the video, I was asked myself 'why haven't I heard of these before?'
One downside is that at $6.95 a set, they are essentially $6.95 per use if all your gas ports are the same size.
Thoughts and comments?

They work but most people use tooth picks.

Conceivably I guess those would work.
Personally I think you’re better off with an actual tool.

I have the above jig and it it’s set up for whatever GB spacing you need and indexes off of the gas port.

Our barrels come standard with a CNC machined dimple opposite the gas port for guess free installation of the gas block.

I have an SLR dimpling jig. Mine is from .750 and is grey, doesn't have the spacings indicated on the edges, and isn't for 5 different spacings either, did they improve the jig recently?
Just thought that it was a clever idea and was surprised I hadn't seen it.

Ah, yea. Each side of the jig has a different spacing spec.
I ordered mine probably 6 months ago I’d guess so it changed atleast some time before that.

That dimpling jig is nice.

I use the Kaw Valley Precision AR-15 Gas Block Dimpling Jig .750 barrels.........I got it because it was the lowest price, best features at the time, and was in stock. Some other brands didn't meet my price or in- stock needs, and I have no complaints with the Kaw Valley after several uses.

Complete waste of money. This is what I posted on TOS:
"On an M4 barrel (.062" gas port), the gas block can be off 4.8° and the gas port will still be aligned. On an M16A2 barrel (.092" gas port), the gas block can be off 2.5° and the gas port will still be aligned. That is all those alignment pins will guarantee. You're telling me you can't line the gas block up by eye better than 2.5°? That far off and it would be leaning nearly 1/16" closer to one side of the handguard than the other. 4.8° off and the gas tube would be binding (if it even fit under the rail that far off).
The only way this could possibly be an issue is if you have a 16" barrel with rifle length gas system with a huge gas port. Even then, it is still off more than 1° and is nearly 1/32" closer to one side of the hand guard than the other. That alignment set probably doesn't have pins that large anyway."
