    Hello everybody,
    I have a Colt 6601, and I have a question about the sights. I have it adjusted to the 3/8 setting (its an a2 rear sight base), which i reckon refers to 300/800 yards?
    Also, For left/right adjustments, when i flip the sights to the smaller aperture, there is a notch in the larger sight aperture which aligns with some notches on the base. If the notch on the aperture is centered with the center notch on the base, does that mean it is aligned left/right?

    Thanks,

    That just shows mechanical zero. actual zero may be left or right of that but it is the zero you base all others from.

    The notch on the aperture that matches the lines on the base is for reference for windage adjustment. I do recommend that once you get the windage set, that you take something and make witness marks for the windage adjustment knob and sight body, like a paint pen or something. That way, if it gets bumped off, you'll know it.

    As for the 3/8 setting...hopefully someone will come along soon to explain it far better than I ever could.

    The elevation adjustment (the 8/3 you see on the dial) is setup so that when it's dialed down your elevation is set for 300 yards, and dialed up its set for 800 yards.

    For sighting in, it should be set to 8/3 and then dialed down 2 clicks (referred to as 8/3 minus 2).

    For your windage, I recommend nail polish applied with a fine paint brush like those used for model ship building.
