Full auto fun or near miss?

As I have fixed the problem there is no way to find out if it would have been full auto or the other two options and I am not going to attempt to replicate the problem to find out.

Regarding the RCMP point, I don't think a weapon's malfunction that results in Full-Auto fire would result in a banning/prohib classification as the factory M14S/M305 is semi-only and can't be made to fire full-auto without significant modifications. I think if swapping stocks resulted in a full auto weapon the RCMP would either charge the individual with creating a prohib weapon (similar to cutting a barrel below 18"), seize the weapon, or whatever it is the RCMP does with illegal firearms.

I am not so sure that the hammer would have ridden forward as the cycling of the action is pretty fast and I am not certain that the tension of the main trigger spring would have kept up with the cycling of the action but like I said earlier I am not sure and I don't want to find out. As well, even if the hammer is riding the bolt forward when the round seats into the chamber wouldn't the hammer strike with enough force to fire off the primer?

It is very hypothetical and pretty damn unsafe. I watched the youtube video and the way it shows the action firing in last portion with the large scale model looks very much like what is happening with the M14 in an M1A stock - the rear trigger catch is not engaging the sear and the hammer is going forward with the bolt. Anyway, it has been 3 days and I haven't been able to get the hammer to drop from the reset position so all is good again in the Norinco M14 world....

No....for a couple of design reasons. The hammer can only strike the firing pin when the bolt is in battery, and the firing pin can only strike the primer when the bolt is in battery. Hammer riding bolt is pretty safe.
On real select fire gas guns, the functon of the auto sear is to release the hammer ONLY once the bolt is in battery.....

I promise you the only thing that would have happened is the hammer would have rode the bolt home and nine chances out of eight it wouldn't even have the force left to fire the primer of the second round. You'd be left with a live round in the chamber and an uncocked hammer. That's it.

I wouldn't say that too hastily. I have an SKS that the previous owner had tinkered with, and let's just say the sear was "slippery". You pulled the charging handle back, let go, and it would spit out a rainbow of all 5 shells. Pretty cool looking, but I only did it once. After the new sear had been installed, it hasn't done it since.

The SKS has a tertiary sear that holds the hammer back until the bolt is safely locked and ready to fire, the M14 does not. The behaviour of one is no indication of the behaviour of the other.

This is correct. The SKS is a different design altogether and "tinkering" with it will give you different results than with the M14.

The tertiary sear prevents hammer release until the bolt carrier is in it's full forward position. What is more likely to have been happening is that with the damaged (or tinkered) sear not holding the hammer as it should, the tertiary sear would hold the hammer until lock up at which point if the worn/tinkered sear slipped the hammer would fall on the pin and detonate the cartridge and all others in the mag in sequence as long as the sear continued to fail. All without the trigger being pulled too I might add...not a good thing.
