Default m1 Carbine post WWII rear sight question

The dovetail portion of the rear sight of my carbine has fallen off the rifle.
First it started to move to the right with use and then came completely off its mount. I took it to a gunsmith twice for re staking but it didn't hold. Any ideas to reattach it to its base.

Try a different site. Or have base of site welded and hand fit it with a tight taper with file and stone.

I’ve used a shim made out of a soda can for one of my rear sights that fell off. So far no issues. I’ve also heard of peening the receiver dovetail to make it tighter.

I think if all the smith is doing is staking, he is just ruining the dove-tail slot beating it all to he!! and back. I’d rather destroy a relatively cheap sight than a very expensive receiver.

If it's just loose in the dovetail clean both the sight base and dovetail well, apply Loctite 620 Retaining Compound (made for gaps between materials) to the dovetail, align and let cure. It won't come loose.

Default Carbine rear sight prob

Thanks guys for your suggestions.
Welding is beyond my skills.
The JB Weld or Loctite 620 sound doable. My only concern would be whether
the the stuff will move as the upper portion is tapped into place.
Certaintly worth a try.

I used Loctite to tighten up an adjustable rear sight that had some play in the dovetail. Mine was not to the point where the sight was coming out of the dovetail so I just cleaned all around the dovetail and sight base then applied the Loctite allowing it to "wick" in and around the seam where the dovetail meets the base of the sight. Been over two years now and still holding tight. I had re-staked this sight and thought I had the problem resolved but it began to have a little wobble again. Not wanting to risk damaging the dovetail/receiver I went with the Loctite and as stated it is holding fine.

Get some Green Loctite. Most all parts stores have it. It is used for preassembled components. It it the "weeping" kind and will wick into the crevices. You may have to apply it twice but it will hold fast if you apply it from both sides, let it sit in an upright position and then do it again after a few hours, wiping off the excess.
