I took my brother with me to the range the other day. I brought out the M-14 and was letting him have a go with it. He was babying the op-rod and when he pulled it back to load a round into the chamber he was riding it forward. Anyway, the damn thing jammed! it bound up with a round pretty much still in the mag and somehow managed to get the operating rod track to jump off the cam on the bolt! :eek: So the op-rod was all the way forward and the bolt was kinda Proped up out of it's track bound up against the back of the round it was trying to load....

Any one experienced this before? I was pretty supprised to see what he had done. Had to field strip it to rectify the problem.
 
I rode the bolt when I first got it and had a failure to fire, thought it was a misfire and waited 60 seconds, yadda yadda, turned out the pin had never hit the primer, it was stuck or something. Not sure what the heck happened, but I looked it over and this time let the bolt ahead on its own and good to go.

Yep, battle rifles don't need to be babied :D
 
Yea that happen to me before but it wasnt when I was loading the rifle. It happen on the third round fired. The op rod had disconnected itself from the bolt cam. I put it back in, fired a few more rounds and same thing. I took it in to Dlask Arms to work their magic and got it back to me a couple days later. Never happen no more. Never figured out what it was. I didnt see any relief or welding spots anywhere on reciever or op rod. Op rod is still original.
 
Just rip it back and let it fly forward. Never, ever baby it.

Taken from the M1A manual:

LOADING AND UNLOADING
CAUTION: WHEN LOADING AND UNLOADING ALWAYS PREPARE THE RIFLE
BY HAVING THE SAFETY ON AND THE RIFLE POINTED IN A SAFE DIRECTION.​
1. Load the magazine by inserting the cartridges one at a time into
the magazine [see figure 3].​
​
​
Place the rifle on safety and point it
in a safe direction.​

2. Insert the magazine into the magazine well with the rear of the
magazine slightly lower than the front. When the front of the
magazine is fully inserted, firmly rock the magazine up and to the
rear until it locks [see figure 4]. You may have to push hard
to accomplish this. When the magazine is properly in place it
cannot be removed without pressing the magazine release.

3. Pull the operating rod handle and thus the bolt, fully to the rear
and release it smartly. If done properly a cartridge should be in
the chamber and the rifle ready to fire after the safety is moved to
the off position. Do not touch the operating rod while it moves
forward, as it needs the fast forward movement to strip a cartridge
from the magazine, push it into the chamber and lock up.​

What probably happened was when he was riding it forward he managed to pull the op-rod lug out of the take down slot (the same way you dissasemble except there is a spring this time).

I have had it happen to me just working the action slowing (no live rounds though) and it is pretty easy to reproduce (not that you would want to).
 
It has happened to me twice. Now I always think of NOT moving the op-rod handle up before I let it go. The first time my gun jammed liked this I had a hard time to assemble it again. Nothing was brokend though :)
