i'm putting a rifle back togther. extracting a broken bolt

[vash]

when i fell, i sheared a fastener. i need to extract it.

are scope allen bolts hardened? this one was clearly loc tited..cuz despite that it is under zero tension i cant turn it.

it's making me worried about the health of the actual rifle. hope i didnt bend something in the fall.

try a reverse drill bit..


Rifles can take a hit, after all, they are designed to withstand repeated heavy pressures inside of them

The allen bolts are just regular hardness and can be drilled out with a regular bit or a left-handed bit. Since it looks like a ridge is on the top of the broken section I would recommend removing the bottom half of the mount and using a drill press with a sleeve around the bit as the bit will wobble. If you use a regular bit the broken piece will go all the way through. I am surprised a bolt, just one broke so maybe they are make of an annealed steel on purpose? Good luck.

I would just get new rings.

This right here, you'll be back in action in no time. Besides, you might be able to find a set cheap at the French Army Surplus (badum bish!)

I second the recommendation on the drill press. Once you get that off, I'd put a couple drops of PB Blaster or Kroil (or your favorite rusted bolt remover) and let that sit for a day, then repeat.

This. Rings aren't too $, and it removes an doubt about the condition of the rings.

this... but that looks like Leupold ring so about $25.00 the screws are soft and could be drilled out. However they are an 8-64 thread you won't find one of those at Lowes. Push to shove I'll look in my tool box junk at the shop if I have one i'll send it to you.

If it has blue loctite on it, wouldn't a bit of heat soften it up?

[John Rogers]

The point about locktite is true as many scope screws are fastened with it. I forgot to mention if you do not have a Weaver Scope Mounting Kit I would very strongly suggest buying on. It has ring alignment tools, bubble levels, inch pound torque wrench and the various sized allen wrenches you might need. At the same time I would order a "gun screw set" and you'll have the needed replacement BUT since you have a set you'll NEVER break another one!

This........ how do you know the ring is true? Do you bed your scopes?

The rings are steel, they won't twist or bend that easy.
There is enough meat on them to resist deformation.

They took a hit and wanted to slide apart, the weakest bit broke, the screw.
The rest is fine.

Easy enough to check, if you put the 2 halves together, they will still fit.
if not, replace em.

[Gretch]

Not enough........ the two rings have to be in alignment with each other. I won't go into the details, but this is exactly why bedding a scope is done, especially when the rings are separate pieces.

just my opinion........... treat your firearms as you see fit.

[svandamme]

I don't see how you would twist the base of the scope rings, and not damage the top half.
Either way, it would be very obvious

[targa911S]

the front ring has a foot on it that twists into the base so it does in fact turn left to right. the rear one has a screw on either side holding it in place on the base. These screws can also be used to adjust windage. Bedding a scope is essential on rimfire guns.

[vash]

That scope was installed by a smith. He did align everything and bedded it. That's why I was hesitant to get new rings. Which I've decided to do. I'll let a gunsmith do it.

Huh Never heard that one . I do bed the receiver and sometimes part of the barrel channel. Will often add a pillar for the take down screws as well.

[targa911S]

Whaaaaaat? Never heard of Leupold dove tail mounting system?

I mean, the ring itself would not be damanged, it could be loose from a hit, but i doubt it would be damaged itself.
It can be rebedded withou replacing, right?
