M1 Rear Sight Problem
I Purchased another M1 and this is the second time while shooting it the Rear Sight keeps walking to the Right. Before doing any Punching or Staking, is there anything i can do to keep this from happening.I have never done this and I would hate to ruin the Dovetail. Thanks OBTW I took it to 2 different places and neither place said they do that type of work.

Try a few drops of blue Loctite in the dovetail. Painte777 (Charlie) recommended that to me for a rear sight and it seems to have worked well.

Thanks, Will it hold it permanent ? I have that Water Activated Gorilla Glue will that work just as good ?

Frank: Use the loctite. Clean the metal as best you can with a good solvent like brake cleaner or gun scrubber to remove all the oil, otherwise the loctite won't hold. I did one on an Inland about 10 years ago with red loctite and it's never come loose. The red is higher strength than the blue. I used the red (#271) just because I had some on hand and knew I could remove the sight if ever needed by using a heat gun and a little extra force. - Bob

From what I understand and have read on other boards, the blue Loctite is what I might call semi permanent. It can be broken loose easier than the red if needed, but still very secure.

Do you know why they call it 'Gorilla' glue? It takes a gorilla to remove it! GK

You can also make a shim to put under the sight to take up the space and force the sight into the groves that hold it in the dove tail. It also depends on what type of rear sight you have. A flip sight or an adjustable rear sight.

You would fire the carbine and mark the correct drift before Loctiting it. In the case of the adjustable sight, center the aperture before firing.

Thanks Guys....I cleaned the surface in the Dovetail and the Rear Sight. I went ahead and bought the Red Loctite and applied it last night. Now im going to let it set before i shoot it this weekend and hoping it Sits. Thanks

I used a shim. One "aluminium can thickness" required about 20 in-lbs of torque to replace the sight. From the adjustment for windage at the range, I knew how much the rear sight needed to be shifted left to get the aperture centered for the zero windage setting. This, and knowledge of the thread pitch for the sight installation tool's ram, told me the number degrees "extra" I needed to apply with the sight tool to get the sight centered. So far, the sight seems to be holding up.
