I have not used this but I have some virgin barrels with undrilled front sight posts I will be using these on.
I could use toothpicks but by the time I sanded them down to size and oiled them up I would have to notch them just right.
Rather just pay the $7.00.
So fricken glad somebody put the money and connections into this. I’m sure millions have been wondeing why somebody hasn’t made them. I don’t know if you could sell these to big industries unless you found out how big the gas holes were and made a bunch of them the same size but for a guy that got a few $80.00 barrels and wants to put new front sight bases its a heck of a lot better than a jig. I will be setting my fsb with a set screw before I drill them out.

Great little product. I ordered two of these a while ago for two builds I was doing. They worked as you show in your video, and were extremely helpful with the clamp-on style gas blocks, since you don’t have a screw to mate up with the dimple some barrels provide. Thank you for a great and helpful tool!

Super Quick and easy to use. I use these every time now knowing that my gas block is always 100% aligned and takes one more little thing out of the equation if you’re troubleshooting your upper.
