I have a ongoing problem with my op-rod guide coming loose. The original rool pin was cracked and I replaced it with a good quality pin and it still moved a lot. I took it apart and JB welded the pin in place and it's loose again after only a couple of hundered rounds. Any tips or who would you send it to?
 
It is supposed to be loose. You can tighten them up using the NM procedure, but you don't really have to. The idea is that the op rod can float around to take into account the movement of the other parts. If you have tried to lock it into place and it is breaking loose you may wish to take it to one of the clinics. I don't know about Hungry but that is one of the things we regularly do at the West Coast clinics.
 
Hungry preaches a roll pin with in a roll pin technique to solve this problem. Search the threads and I'm sure you will find a description. I'm sure it's described in the video as well. Better yet attend one of Hungry's clinics. I pinned mine at the SG clinic. The solution works!


Per a post from Hungry:

"Okay here's the situation.... I often replace the stupid cheesy roll pins that the Kommunists use to secure the op rod guide on the Norinco barrel. I employ a 1/8" diam x 3/4" long roll pin that slides in and out of the existing factory hole (that used to employ a metric pin).

Then I would flare open that pin while it's halfway INTO the op rod guide (hole), FLARE it wider/open with a very specialized 'flaring' tool that only the M14 clinic attendees from the SW Ontario (EESA hosted) session will know

After it's opened up a bit, I will drive in a 1/16" diam x 1/2" long roll pin INTO the 1/8" diameter roll pin. This combination will solve the loose oprod guide problematic to many of the Norinco M14."

I went to one of the first clinics years ago. I still get movement with a tight fitting roll pin. I was thinking of knurleing the barrel to slow the movement and the re JB welding it.
