    Ok, how the :cuss: do you keep a Leupold mount secure? This is the sporterized M1903A3 I inherited from my father-in-law when he passed away, and I have it drilled and tap for a Leupold mount.

    This is my third attempt to keep that rear mount secure, and it worked for the first twenty rounds, enough to get it sighted in out to 200 yards and then it let go. Again. For the third time.

    :banghead::banghead::banghead::banghead::banghead::cuss::banghead::banghead:

    Any suggestions? Red Loctite? Silver solder? Duct tape? Arc welding?

    Any help at all would be MUCHLY appreciated.

    Thanks.

    I have never heard of one failing.

    It appears to me you have a defective ring.
    Or a ring Leupold didn't make in the first place.

    There should be a sort of reverse dovetail taper on the ring post where the windage screws clamp it down.

    Once clamped down, it should never come loose again by itself.

    The only other possibility I can come up with is, your 0303 rear receiver ring was ground off too much, or crooked, before drilling & tapping.
    And the ring isn't seating all the way down in the base without springing the scope tube.

    The photo seems to show the ring isn't even where it belongs to line up with the screws in the base.

    I'd take the scope out of the rings.
    Then mount the rings in the base.
    Then mount the scope in the rings.

    That will insure the rings and base line up where they have to line up to stay put.

    it looks to me that the ring is cracked or chipped where it meets up with the screw for the base. if there is not a dovetail there, there is nothing for on the ring for the screw to attach to.

    You are using the wrong rear ring. I checked my 03-A4, it uses a narrow rear ring and the windage adjustment large head screw locks into it. Try contacting Val Forgett Jr. at Gibbs Rifle in Va. He was having some repro 03-A4 rifles made up, and may have spare rings. You may also try Gun Parts in West Hurley, N.Y. Good luck! Bob

    One of the worst mounts money can buy. They are designed for guns that had to be tapped after purchase and often had holes not drilled correctly. Unless you need to use them to get enough windage adjustment I'd trash them and use anything else.
