    :

    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.
