So, I've determined that my Norc M14 is over-indexed. When looking down the iron sights, the front sight blade is canted to the left, indicating an over-tightened barrel.

I've checked the stickies extensively, but a lot of the photo-links are broken. As such, there seems to be limited guidance/information available.

Is it as simple as, vise the barrel down, remove the barrel retaining screw, unscrew the barrel from the reciever until it's in correct alignment? Or should I just look for a gunsmith?

Help a guy out?
 
Barrel vice, receiver wrench , remove barrel screw, index.
Your headspace will increase very little. Reassemble.
Shoot shoot shoot :)
 
With the right tools its an easy fix and its basically as you described. No need to remove the barrel set screw .
If you are stuck I can do it for you for the price of some liquid refreshment while doing it. . I live about 2.5 hrs NW of you.
Ensure the sight base is actually straight as I had one that was made at an angle .


Here a couple pics from 2 different clinics Hungry put on a couple years ago

Those pictures help a lot actually. Thanks kindly chalk, I may make the drive. Petawawa area?
 
Next town west in Chalkriver . It takes longer getting the thing set up then to do the job .
Have you taken the flashider off yet ? Does the op rod guide have any play in it at all ?
Does the gas cylinder lock get nice and tight at the 6:00 position ?
We can fix that pretty easily as well. :)

I thought my index was out to but it turned out to be the norinco flash hider was not machined true. Just something to check.

I had both problems. Replacing the Norinco flash hider with a Springfield MB nearly corrected the front sight issue, but it's still out by a degree or two. It went from unusable to acceptable. (There was no more room left to drift the sights with the factory FH... LOL)

One of these days, I'll make it to a clinic to finish the job...

At my last m14 clinic this was true with many of the rifles present. With levelling bars on the receiver and norinco flash hider the indication was out of index. Slipping on the usgi flash hider and on most the bars were level, indicating that the chinese flash hider was the problem.
We only had to reindex 3 rifles out of the 15 present. I think we got lucky tho as barrel indexing has always been hit n miss on these rifles, some worse than others.
 
For leveling bars, does a guy just use a couple thin, flat bar, steel pieces? They just need to be straight and true correct? Or do you guys use something special for leveling?

Cheers! :)
 
Those will work...anything that is straight like in the pics I put up earlier .
I use 3 sections of m-305 cleaning rods screwed together so 6 in total...about the only thing they are good for .
I saw a thread where a guy used carbon arrows .

And that's what I've been noticing at our clinics, once we get that flash hider off and replace it with an American flash suppressor, we discover that the chinese unit is a bit on the canted side or machined off angle / crooked/slanted/ goofy.

Cheers and keep helping them nooobies out there! :wave:
