    I committed the cardinal sin of over-torquing my scope ring screws and breaking BOTH of them on one mount. The irony is that I've put scopes on 5-6 rifles in the past few years and switched scopes, etc., all by feel and never had a torque wrench. So, I buy a new one, use it, and come away with a mess. So, I'm taking it to a gunsmith, but he's backed up for a month. So.....do you guys have any suggestions about how to remove the broken screw stumps that are now stuck in my rifle? Oh and I'll gladly bend over for a well deserved swift kick.

    What size screws? Ezy-outs?

    If the screws go all the way thru, maybe use smaller bit on opposite side into the screw may back them out.

    Nope, no ezy-outs. Only good news, I did not use lock-tite

    Ouch

    Could have been worse.
    Did you put blue locktite on them?

    Drill from bottom MIGHT work, if you have a way yo hold securely and a drill press. Otherwise, bit will slip off screw and go through the softer aluminum of the rings.

    A small EZ-Out should do it.

    I would just buy new rings.

    If you post a pic we could see what the situation is better. I am picturing no good access from the other side.

    My first thought is reverse twist drill bits.

    EZ-outs are never EZ.

    Use a TIG welder to weld a lump on top of the stub & unscrew it.

    EZouts work but there are better ways. Assuming that the selection of tools is pretty basic I would say to try a reverse drill bit. It will either back the broken piece out, or it will drill a hole in which to use the EZout. Harbor freight is your friend, their screw extractors as a set cost what a single name brand piece would cost. I have a set from HF and a couple Irwin extractors from work and they all work about the same. Just don’t be afraid to put some weight on the extractor to get it to bite. Once it bites into the broken bolt your done, but if it slips very much it can booger up the extractor.

    If the screws are through holes a standard drill bit will generally grab and screw them all the way through. If they are blind I would start with a left handed drill bit and peck a bit evaluating progress. Maybe you'll get lucky.if things go sideways you may end up cutting a new hole with an end mill and rethreading one size larger.

    Thanks for the thoughts guys. It convinces me to wait the month and let the gunsmith do it.

    Most auto parts stores sell left twist drill bits. Thats what I would suggest.

    I’d start with a left handed drill bit. If the head is broken off, the torque value is lost, so I bet they turn right out

    Sometimes you can spin them out with a pic if the break is not flat to try a left hand bit. It's not hard to grind your own left hand/ easy out bit, even with a file. I'd have to see the screws to see what id do.

    These Grabit Micro-bits are the best! I have used them for gunsmith sized fasteners (most hardware stores don't have these small sizes), sight set screws, optic mounting etc.
    Easy to use with cordless drill at slow speed; mount the object of interest firmly in a vise, blue tape off the fastener and away you go. You can spend a lot more on specialty micro drill
    bits then use extractors, but no need to. Remember set your drill to REVERSE for both drill / extraction with the double ended bits.

    You're missing a picture.

    If you broke the screws off. . . they should be loose now that they have no heads, right?

    Without a picture, you're the only one who knows what's going on.

    If I understand your problem, the top half of the scope ring is off leaving the broken screws in the lower? I have removed numerous such screws by slotting them with a thin cut-off disc in my Dremel. I keep a thin bladed screwdriver that fits the slot just for this purpose. The cut-off wheel will heat the screw and soften any thread locker if present. If the screws are flush with the top of the ring, the slot may extend into the base metal but if carefully done, it will be covered by the top ring when completed.

    Sorry to confuse you guys. The ring/mount is a one piece Talley, see link. I twisted off both; clearly a dumba** move. So, my rifle now has two plugged mounting holes, which are plugged with the screw stumps, the slotted head having been twisted off. Clear?

    Find a jeweler or a clock repair that will work on firearms. I have read that a clay or wax dam built up around the screw holes and a mild acid will loosen broken off screws. Even Coca Cola has been known to work. I have used a carbide bit and a Dremel in your situation. Get a good steady rest and a good night rest.

    Good thread guys. The only cautionary addition I have is not use a power tool to install things.

    All you have to do is post a picture and it would prevent all this confusion.

    I think I know what you are talking about. You effectively plugged the mounting holes in the rifle, right? So there are tiny little plugs that need to be removed which I have no idea how to do without buggering the rifle.

    OP's decision to wait for a gunsmith seems wise.

    Great thread guys! I hope I can remember where to find it the next time I over torque a screw and remove the head.

    Let he who has not torn the head from the screw body, throw the first easy out!

    Why? Copy and paste the specific posts you want to remember into a power point slide or word .doc and save. Be sure to copy the url, then you can access the whole thread

    I am in the TIG group. All sorts of tiny things can be removed if you are careful.

    Just build the bead up backwards, until you can get ahold of it with something.
