I'm gonna wade in here. Last year I was invited to a particular Amorer's workshop (I cannot mention which agency) to deliver an M14 clinic. Don't even ask who belongs to the Norinco M14's!! I'm not at liberty to say anything except that with Box STOCK Norinco M14's that are hand tuned inside their chu wood stocks, these rifles shot INSIDE 3/4" and many 1/2". I peered through their 'binders' of targets. I was impressed. The techniques they used are all from my clinic which are all from NRA publications since I did not invent them. I just pass them on with my brand of stale jokes. 
We did carry out unitizing / welding of the gas cylinders (because all of them can weld) and I happen to be there standing over them with the 'finger of authority' pointing away. We shimmed their gas cylinder assemblies and re-assembled then test fired. Still hovering around 1/2" groups....
I was freaking amazed. Yes, they were shooting iron sights & sandbagged benched rifles. I had a tough time believing this until I saw it myself. I was amazed. 
I showed them how to smooooothe their trigger (read: NOT reduce the weight) sear engagements. Those of you who have been to my clinics know this means, it ain't rocket science nor a state secret. They already had my DVD of the 2004 Abbotsford Clinic downloaded.
We pulled off (read: Whack the fzck out of it) the flash suppressors so that they can get at their gas cylinder assemblies. I did pass on the NavyShooter method that I just learned from the Halifax M14 Clinic the previous Sep 26, 2009. Thanks, Atlantic Marksmen Club! Thanks, NavyShooter... you made me look like a pro.
I cannot forget to mention that these master-craftsmen shot factory loaded match ammo (read: 168 gr Sierra MK's). The whole day was in a fog and vacuum and sometimes I shake my head to see if I was awake the entire time in this location. These dudes are fantastic. They know how to make the M14 Norc shoot!
I cannot say anymore due to confidentiality agreements/expectations.
I will close off by saying that these folks did everything using the "Hungry Welfare Methods" (keep it cheap, that's my plan) and certainly did not pump a great deal of money into their M14 platform(s). I keep reinforcing (around this forum) for all of you to save yer money! Buy practice ammo/reloading components and shoot your M14 (fzcking lots & lots) !!
Hope this clears up any confusion flying around this thread!
