IAI carbine rear sight stake?

[Rick the Librarian]

One of my relatives (and my shooting buddy) has a IAI-made M1 carbine (one of those commemorative models they sold a few years ago). He is having trouble getting the rear sight to stay "fastened". He wanted to find out:

1) How was the rear sight on this model fastened?

2) Any suggested "fix" if it won't stay tight?

Also, ballpark idea of worth/value if in ex. condition?

TIA!!

I assume that you mean that you're dealing with an oversized dovetail; the entire sight body moves from side to side? The first thing I'd do is to see if there's any warranty fix available as such a repair can get a bit problematic.
Understand that the dovetail is hardened metal. The GI fix of peening the upper lip downward a bit (to slightly close up the dovetail) and/or staking the sight can result in a chipped or broken lip if you don't know what you're doing.
Then too you have the matter of pressing (or driving) the sight assy. back into a repaired dovetail slot. Without the GI tool you need to chuck the receiver up in a padded vise and drive the sight (from right to left) into the dovetail with a brass drift to it's proper position. One slip and the sight or dovetail may be damaged.
A possible "bubba" type fix might be to affix the the sight with some sort of epoxy.

I have followed the staking procedure in TM9-1276 Cal. .30 Carbines M1, M1A1, M2, and M3 both to decrease the size of the dovetail and to stake in place on multiple carbines with no trouble or chips.

Unless IMI receivers are more brittle than US GI ones, there should be no problem.

Disclaimer: If your nickname is Bubba and you approach everything with a 9 lb. hammer swung with all the force you can muster do not attempt any gunsmithing.

Sight pushers are very nice, but a brass drift also works, especially if you are careful how tight you make the dovetail.

I wonder how well just a drop of locktite would work. Later a little laquer thinner should remove it if it needs to be changed. No staking or "Bubba" involved.

I had to swap out rear sights on my IAI carbine. The type 2 broke, so I put on a type 3. It was a little tighter than a GI base, so the sight was nice and tight. If it's too loose, I'd try some Loctite Guntite glue to keep it in place. My IAI carbine was one of the early ones that had all GI parts except the barrel and receiver.

Thanks for the suggestions, guys. My friend was very impressed!

Rick,
There was a seller in Texas who had several on his table at many different shows. He was asking $450 each but they didn't seem to be moving very well.
I guess the value would be higher by the quantity of, and maker of the USGI parts it's assembled from (?)

How's the new CSP job working out? Are they matching stock in your 401K?
