    What is the best way to find the center line of a round barrel when mounting a front sight?

    Totally round or octagon to round? With an O/R you can lay it on a flat surface with the top flat down and rub the muzzle end on some abrasive material to make a mark on the top center.

    Hi,
    EC121 has the right idea. I use a flat needle file instead of paper.

    What if the barrel is as he described...round?
    Bud, is there a rear sight installed, or is it bare for both sights?

    Hi,
    Easy, you do it with the breech plug installed and make sure the flat tang is flat on the surface.

    On my shotguns barrel I wanted to place a small front blade in the event I ever wanted to fire RB. After I mounted the barrel into the stock I took a thin sharpie and marked two spots on the centerline of the top flat(octagon to round bbl), then took a piece of string and taped it on the two marks then held the string straight to the end of the bore then marked accordingly. Worked well enough.

    I use the tang bolt slot and the blade as rudimentary sights.
