Sorry about not having pics right this second, but I'm having trouble seating the trigger guard back into place after disassembly. The stock seems a bit oversized and pulling back on the trigger guard to seat it back into place, the rear of the trigger guard is up against the plastic of the stock and I can't seat that little tab into the rest of the assembly. It took using one of the rods from the GI tool to get it out in the first place, and it won't go back in. I'm not exactly a lightweight but even with two people we couldn't get it in... it seats (with some force, obviously) well enough when not in the stock/receiver.

Would it be sensible to remove a bit of the material of the stock to make this easier? I was just going to file it down back behind the tab a bit, but figured I'd come to you guys first before I did anything.

Picture relevant. The whole trigger assembly seems to seat really deep in the stock and it's the back cutout in the stock (down at the bottom right of the assembly) that I want to file down. Obviously... after disassembly, not with all the bits in.

there looks to be enough space. Just smack it in hard (slightly rearwards). It should seat

Tried that... several times. A couple times with a mallet. Just have a sore hand now... I think it's a no go, sadly. =(

Here's a pic to illustrate, applying downward and rearward pressure. Not even that much, much as my grip strength can go. The back of the guard is basically flush with the plastic of the stock there, and it's nowhere near seating. Aside from stray bits of plastic I'll have to keep clean, if I disassemble and have at the stock with a file, shouldn't really affect much should it? Besides the stock resale value, I guess? If anyone wants a Norc stock?

Is the hammer locked back?

Mine look like that and they seat well with a good smack of my hand.
(smack it when it starts to tighten up, when the tab is still near the bottom tip of the trigger)

Hammer's locked back. It ought to be, right? I tried smacking it from that position just now a few times as hard as I could, got nothing. =( I did earlier recruit a family member to pull back on the guard with the GI tool rod, and try smacking it while they were pulling back... also got nothing.
 
The only other thing I can think of is that the receiver or trigger group is not seated all the way in before you are trying to lock it into place.

It had to lock in at one time. I use a 2' length of 2x4 to seat stubborn Garand trigger assemblies. The trigger guard can be tweaked (bent) a little to get an easier lockup.

What'd you tweak it with? And did you have to disassemble the whole trigger group to tweak it? I'm giving up for the night. This is how beaten up the steel has gotten over the last little while with my repeated banging and cursing. First disassembly too... it was all going so well until the very last step.

That said, as someone who's usually mechanically and electrically inclined, I can see why M14 owners get addicted. I just want to fix it dammit.
 
I lied. I stayed up a lot later than intended trying to fix it. Broke out all the tools I had short of filing down that stock, which I may do if nothing else occurs to me. It's tight as it is on its own but it's flipping impossible in the stock. My wrists are tired, I'm tired, I'm going to bed so I can make it up in the morning.

I checked how the receiver was fitting and it's flush against the top of the stock. The trigger group looks flush against the receiver with the guard down (after it tightens up). Storing it till I've more time to play with it... so... probably tomorrow, hah.
 
Had the same problem with my Norinco. Couldn't get it back in the original stock.
Don't know if they are assembled with 2-ton presses. ;)

I put it into another stock and ended up doing a bit of filing before it would fit.

Good to know. Gonna try filing then.
 
With the trigger assy out of the stock, that trigger guard tab should SNAP (audiable) into the trigger base frame notch with out much force at all. If not I would say that your trigger guard is warped (or out of spec) and needs to be tweaked. Either bend the trigger guard (not sure this is feasible) or file the tab and notch (just a little at a time, until it engages without having to beat on it).

Did you tear down your trigger group and re-assy prior to this happening? Could be something is not installed quite right. Just a WAG.

If the trigger assy out of the stock closes fine, then you have a stock (trigger assy seating) issue. Are you sure you are seating the trigger assy into the stock properly? Some times I mess that up the first go when assembling. To me your trigger assy looks to be seating way too deep and forward into the stock (could just be the stock I guess or the photos? I run USGI wood).

I'm seeing more than a few Norc trigger assy and stocks being offered up on the EE these days. Maybe something to consider.

As someone mentioned already, trying a different stock will sometimes point to the real issue.

Take my advise with a grain of salt, I'm not a gunsmith, but I have been putzing with these things for more than a few years now.

I had this problem as well with one of my M305 rifles, and the solution had nothing whatsoever to do with the plastic on the stock: it was the metal stock liner that was the issue. The metal stock liner was actually incorrectly shaped, preventing the trigger group assembly from being pushed down far enough to lock in. After I corrected the angle of the liner with a Dremel the problem was resolved.

Interesting. The stock liner did cross my mind as a potential problem source. I have owned nothing but the original Chu wood stock and numerous USGI stocks. Never had a liner problem with any of them. What part of the liner wasn't the correct shape?

The angle of the channel between the two receiver tabs on one side wasn't cut right and had to be ground to correct specifications. I also shortened the ends of the tabs a millimetre or two to ensure they weren't too long.

It was clearly evident once I was looking right at it that hard contact was being made by the receiver lugs in a specific area of the stock liner. How the hell they managed to assemble the rifle at the factory escapes me, but I couldn't use the stock with any receiver until I fixed it.

The primary symptom of this issue for me was an inability to seat the barreled action into the stock so the rear of the receiver seated fully against the stock.
 
Interesting. I'll have to have a look at my liner. From what I remember the rear of the receiver was seated properly, but I'll have a look when I'm home tonight. I'll likely take a file to slowly adjust the stock slightly as well just to see if that fixes it.

With the assembly out of the stock it is fairly tight and doesn't snap in without pulling back on it first, but it is definitely doable. I shall see what adjustments I can make.

The original plan for this rifle was to put it into a Blackfeather chassis eventually, but that was a long term plan in the build... I may have to step that bit up, but I'll see if I can't fix it in the Norc stock first cause I'd like to go shoot it, haha.
