I am fitting my Norinco M14 to a fiberglass stock. I have only the (presumably) USGI fiberglass stock and the Norinco hardware and upper guard.

1) The front of the stock rests with only slight tension pressing down on the metal plate of the gas mechanism. There is space between the botom edge of the top hand guard and the main stock. If you apply any tension downward on the handguard, there is play created between the tip of the lower stock and the metal plate of the gas mechanism.

2) Should I be using a USGI top handguard? (does it differ from the Norinco?)

3) Does the gap between the top handguard and main stock suggest a problem? It certainly allows play

4) How should the stock be tensioned or fitted for best accuracy?

Picture a gap running the full length along where the top handguard meets the stock. You can squeeze the gap closed, of course flexing something. Its larger gap on one side than the other, and tapers with more gap towards the muzzle.
 
It is better if the handguard doesn't touch the stock. I sanded my handguard down so it wouldn't. Not that it exerts much upwards pressure on the barrel away from the stock but every little bit helps.
 
I just recently put my Norc. in a U.S.G.I. stock with no problem hand guard has only slight gap which for what I have seen is desired. There seems to be a bit of a gap between the receiver and the stock but I am told this is normal.
 
Don't forget to put in a longer guide rod retaining pin or find some way to take up the space in the stock where the longer U.S. pin would be, otherwise your spring guide rod could come out!! The handguard should not touch the stock except at the rear and the front with the retaining bands. As you fire, the barrel "Whips", if the handguard is touching is will cause fliers!!

So this should work properly with the Norinco handguard, eh? Perhaps there is some fitment problem with the action dropping fully into the stock. I just didn't like the look of the gap, and the lack of tight fit, especially at the front end of the stock to the retaining band.
 
you guys really need to READ THE STICKIES on this forum- every question/comment HAS BEEN COVERED THERE
 
Sorry, but I can't find anything in the stickies of this forum that discusses pairing a Norinco handguard with a USGI stock, or mention of gaps between the handguard and stock, or correct amount of tension or play at the muzzle end of the stock.
 
Problem solved. The action sits on top of the top surface of the stock. It was too high on the right hand side. Also, I removed some of the epoxy from the area it was built up to prevent the rod pin from moving laterally, as the action sat on top of that high spot, and filed down some of the top right surface of the stock to even things up on both sides of the action in the stock and the gaps at the handguard. Looks good now. Now to decide on a paint scheme.
 
For anyone else following this thread here is what I have gathered regarding the fit of the receiver to the stock and tension between the ferule and the the barrel ring:

Most of us want the receiver heel to contact the wood for about 1 inch. There should be about an inch or 1.5 of "air" (no contact) forward of that, and then both side rails should mate fully and evenly with the wood on each side. It looks like you need to solve that first by seeing why it doesn't contact properly. Some receivers have a ridge on the right side that causes this.

The receiver should make contact with the stock except for the area from behind the stripper clip guide until about one and one half inches from the rear of the receiver.

The stock furrel and the handguard retainer need to have a firm contact with the bottom of the hanguard tab centered on the furrel. Usually the contact pressure should require both hands to move the stock furrel off the handguard tab.

There should be no gap at the heel, between the stock and the heel. There should be a gap ahead of the heel (as in foreward of) but the heel should have good contact.
I have a springfield that had a gap at the heel and had to refit the stock to the receiver. A gap at the heel does no good for accuracy.

The barrel should not properly contact the stock, but the bottom lip of the barrel band should be in tension with the stock ferrule. Via this contact point, the M14 barrel is in contact with the stock. Anyway, a firm one handed squeze of the barrel and stock towards each other should open a gap between the barrel band and stock ferule that permits you to slip the crocus cloth into the gap to polish the contact points. Then release your grasp and move crocus cloth back and forth under pressure of the barrel band and stock ferule. When done, be sure to squeze the gap open again and inject the same grease you use on the bolt ways into the gap. This process should enhance the match rifle's consistency of returning to the same position after recovery from recoil.

from all ive read you are correct, i think something like 40 pounds of tension is supposed to be on the band and ferrule to force the rifle parts to re-orient themselves to the same position quickly after every shot....the reason for polishing and lube.

how much of a gap is there between the handguard and stock up front?
should be about 1/8" tapering down towards the receiver.
if that looks good i think SER is right, as much as i would hate to pull the action out of the bedding its the only thing left to check....there may be a foreign object lodged under the oprod guide or gas cylinder or there was not any clearance to begin with.

I bought mine on the equipment exchange forum here. Getting one from the states might be a challenge, they are giving everyone grief about gun parts. Boyds can't ship unfinished stocks right now, and before that it was ok if it didn't exceed $100.
 
As a follow up, I used JB weld epoxy to bed the rear of the receiver and beneath the rails, positioning it to achieve some substantial tension between the barrel ring and stock ferule. Took the gun out and shot a couple of boxes of ammo through it and I am very impressed with the accuracy. These are good guns for sure.
