carbine late rear sights

[imntxs554]

Is this possible...When you use that Black Box like Tool to remove a Rear Sight and the Sight is Not budging even when you oiled it overnight can the Receiver start to bend inwards from the bottom when your applying more strength ? I have a friend who insists on Breaking down his Carbine and trying to fix something when he doesn't know much about it, but can Shoot and hold his own against us old Grunts (at Short distances) brought it over and ask me to pull back the Slide and Cycle it and that's when he told me he was changing out his Rear Sight and felt something different. Well right when the Bolt was starting to move towards the dovetail it felt Tight nothing like I've felt before. That's what I was looking through my Books just to see if there was something about that happening. Now that I exhausted what and where I would look to find Answers I didn't, so now I'm asking if anyone thinks it can happen and what can you do about it. One thing I know for Sure now is that I will not loan him any of my Carbines anymore when he goes Shooting with his friends.

That's exactly like the one he bought over.

Frank,
I find it hard to believe he was able to torque on that allen wrench hard enough to bend the receiver, IF he did it all by hand.
Both USGI Bob and I have one like pictured.

Do you think he might have stuck the receiver in a vice ?
Look for any damage/crush on the Op Slide spring housing.
Just to double check, see if the Op slide arm is still straight.
Most importantly: I'd also measure the receiver width across the top and bottom at the rear, middle and front.

I'd also like to add, Check to be SURE that both bolt lugs and tracks are lubed.

A fellow member shared this on another forum:

"I must mention an experience I had recently. After a thorough cleaning and before oiling, the slide and bolt refused to move rearward to test function,
but after oiling the lugs, it cycled smooth as silk."

Please keep us posted,
I'll check back in tomorrow morning

Oh Yeah Charlie I had Plenty of questions and doubts also, but I've Shot that Carbine Several Times when I overhauled it or he would say something was wrong and we meet at the P&,R Club and I would Shoot it then to feel how tight it felt when pulling the Slide back it was Tight. I grabbed 3 of my Carbines and we both cycle them and it was like night and day. He didn't want to leave it but I told him that we had to take measurements, so that's the next Step. I've had a bottom lug Crack on me a long time ago and I never knew why. That's why I'm wanting find out what happened. I had to accept what he said he did. I even told him that if it was that tight I was surprised that he didn't chip off a chunk of metal on the Dovetail.

I also have that set of Tools to Remove and Install the Rear Sight and the tool for the Front Sight as well and I have Never had to use so much strength to remove a Rear Sight

Here are a few Rear Sights that I Hope the Price has climbed so I can get some of that Cash..

Jeez, I go do other things most of the day including taking notes to share on (3) of my carbine's rear sights. Got too late, so come back to turn off this computer and find that I'm a couple pages behind on what's going on! Need to get back on here tomorrow before I'm totally behind! I was wrong about none of them having a marked leaf - the S'G' sight does. Also, my rear sight tool came from Nick Daily, but I do have some other tools from Matrix. See you guys tomorrow, but I'll be getting a late start.

@ Frank - Too late to type up my notes and PM you tonight. Maybe I can get them polished up a bit and post them here instead.

One of those flips is very suspect even from the distance shown. Several have features begging for closer inspection.

Here's the information I put together after checking out the Type 1 rear sights on (3) of my Carbines. I have (2) 6 digit Inlands, but only looked at one of them, figuring there probably wouldn't be much difference between the two. - Bob

Sight #1 - Winchester 5.6M

Marking: Base, square "S" only (Lyman)

- There's a tendency for the leaf to stop at the halfway point, but just barely wants to stay there.
- The leaf can be placed very close to the halfway point and will stay put, without moving to it.
- With the short leaf "up" there's a bit of play, and it can stay slightly forward of vertical.
- The spring has very little room for "fore and aft' movement as the leaf position is changed.
- The pin is centered on the short leaf and is off-center slightly on the tall one.

Sight #2 - Saginaw S'G' 1.8M

Marking: Base, "B-IP" (Blackburn), "S"
Leaf, "RG-S'G' (Redfield)

- There's a definite "stop" at the halfway point, but doesn't return there if relocated a bit.
- The leaf locks firmly in both sighting positions with no felt play at either.
- The spring has more room for "fore and aft" movement, and uses it all as the leaf position is changed.
- The pin is centered more closely on the tall leaf than it is on the short one.

Sight #3 - Inland 476K

Marking: Base, "S -" only (Hemphill?)

- There's absolutely no felt tendency of the leaf wanting to stop at the halfway point. NONE.
- The leaf locks firmly in both sighting positions with no felt play at either.
- The spring has more room for "for and aft" movement, very similar to that on the S'G' sight.
- The pin is very close to being centered on both the short and tall parts of the leaf, but
there is a slight difference depending on which side you are viewing from.

The 4th from the left looks kind of "skinny." - Bob
