How can I fix this?

[lewdogg21]

A few years back I broke off the tip off my star head bit tightening down the rings on this sig scope. Is it reasonably possible to save the rings and get that bit out? If so how? I'm thinking of selling the rifle and keeping the glass so I'm asking. The scope is torqued down to whatever the mfgr specs are as I used a torque wrench, it just broke off the very last turn and I learned my lesson.

Drill it out.

Drill and tap. Or sacrifice the ring and cut it

I previously tried using a very small diameter drill bit and it just walked around on the surface is there a better technique to utilize?

Drill press or extractor? Last resort you could send it to a shop

Cordless drill. I don't have a drill press. I'll cut the ring as it's cheaper than a shop if necessary.

You got a extractor set or screw that size? Cutting fluid? It might take you a lot more force.

Try to drill it out with a left hand drill bit. Dont forget to put the drill motor in reverse. Usually the twisting movement and the heat generated will spin the screws out. If that doesn't work then try an ez out. Be sure to use a slightly smaller bit so you don't damage the threads. Good luck

Or if you have a Dremel and it?s enough space, you can cut it or file it to be a flat head and do it that way

So... I am no scope guru but I have some space between the top and bottom ring halves on my rifles. In some cases there might be enough space to get a hacksaw (or better thin cutting tool) into that space and just carefully cut the bolt? I see there is not really any space to get a whole hacksaw blade in there but... there might be some way to get some cutting implement into that gap between the ring halves, if there is one.

MIGHT leave enough of a nub to grab the remnant sticking out of the lower ring with pliers and twist off?

Tiny size for sure...

I've used something like this. I think the brand I have is Milwaukee. It worked surprisingly well on deck screws. Dont know if they have a small enough one for your application.

"Don't drill it out". Use a brass drift or punch the same size as the fastener, give it a few light to moderate blows with a hammer and it more then likely fall out on its own. You can move to a steel punch if necessary.

Reverse drill bit extractor and be prepared to tap if needed. I recently removed a broken hardened screw from a ruger hand guard ring.
I got lucky when using reverse drill bit extractor that little tiny screw came right out.
Prior to removing mask area real good (duct tape) use a good penetrating solution and and have at it.

I used duct tape rather than masking tape because drill bit will wonder.

Good luck ��
