Got the new Norinco M14 from Ellwood Epps today & was so excited!
:runaway:
So I preceded to strip her down and get that cosmoline off and lube her up proper like until...
I noticed my Op Rod Guide wiggled so much that I could have been one of those DJ's in a night club. So I proceeded to tap the Op Rod Guide Pin out and slap in a new one. This only made the problem even worse. The pin is in there solid but it still wiggle's. I also tried a spare that I had kicking around and yet again still wiggling. So what do you guy's think is causing it to play like this? Should I take out this barrel and slap in my spare? Totally lost on this one...
:mad:
 
Too much tolerance in the splines. That can likely be corrected by peening or knurling to tighten it up.

On the other hand I have an old batch Norinco that is loose, even the barrel band rattles, and it shoots accurately.
 
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."
 
That's what they did to mine at the Halifax clinic. When they removed the old roll pin, it turned out that it had broken into multiple pieces. Though the op rod guide still wiggles a little, it is nowhere near as bad as it was before.
 
a mechanic's auto strike center punch to peen the barrel under the op rod guide, and some red loctite, and a new roll pin should fix your loose op rod guide.

When you are peening [ cratering ] the barrel, put a little extra effort into the edges of the half round hole/roll pin slot , to tighten up the slot
 
LAZ fixed my guide in his method as described above. Worked great. Have also watched him do it to other loose - or off centered - Op Rod Guides with same great result. If I might add (to illustrate LAZ's method) - first your remove the pin (as you have done). Next slide the guide down the barrel slightly away from it's mounting. Then you peen the mounting area on the barrel (formerly under the guide) with the auto strike punch. The punch impact will raise little shards of steel. These shards will then contact the Guide when you bring it back into position (after putting some Red Loctite on the worked area). Center the guide, reinsert the pin and let it set up in the loctite for 24 hours. LAZ does it all in a few minutes, but it takes the rest of us a little longer. Hope that helps.
