Re: Ivey 50 moa adjustable rings

Those definately look more precise than the Barrett rings... The Barrett rings are adjustable by trial and error, when compared to the Ivey rings.... a price to pay.

    That front ring looks like it's happy to see me. [img]images/icons/grin.gif[/img] LOL

    Randy

    Do you know what the approximate height of the rings are? measured from the top of the scope base to the middle of the scope tube?

    Randy,

    Assuming they must calibrated for a certain spacing apart to be accurate, what distance is it and is it measured on center of at their maximum width apart? This would dictate what tubes would fit and what wouldn't. These are made to be used in conjunction with internal vertical scope adjustment or as a stand alone that would be more accurate?

    Do they offer one that's all steel?

    Brent and SR90,

    distance from center of 30 mm tube to top of mount is .7 inches.

    Spacing of feet is set at 4 inches for short action and 4.75 for long. A different cam goes into each one to give it a 50 MOA maximum.

    As to the question as to whether these were meant to be more precise than internal scope measurements.....
    They may just be, but that is not the intended use. They are meant to supplement internal use for those that need major elevation changes with finer adjustments made with the scope.

    This allows you to keep near the center of an internal scope no mattter what the need. Could you make a 3 moa adjustment with the micrometer, absolutely. Keep a notepad handy, though!!!!

    I will post a cross section drawing of the mount in a few minutes.
