Old school norc

[Blkhrt13]

I recently bought an old norinco sks in an early made side folding synthetic stock. I got a pretty fair deal on it. But bought it without putting my hands on it. Now that I’m holding it. I realize the action and barrel are rocking in the stock. I have two ideas. One is build up the stock just a hair with jb weld and file it till it fits tight as I can. The other is basically the same idea but using a brass washer and an 82 degree brass screw. I think first I will stack shim stock till I figure out how much I need. Am I being lazy or is there a better way?

Acraglass.

Acraglass.

Yep. That or something similar like DEVCON is what I would use. But a plastic stock is not like wood and requires a bit more work to get it to lock/stay in place.

Yep, you need to bed it with Acraglass or equivalent. I've owned two SKS's, a Norinco and a Yugo, and both needed bedding. Both had perceptible (i.e. I could feel it) back-and-forth movement of the action in the military stock. Both would shoot two groups, separated by several inches, at 100 yards. Which group the next bullet went into depended on where the stock settled after the previous shot.

Glass bedding fixed it both times. I got rid of the Norc but still have the Yugo, and after having been bedded it stays in the 9 ring all day long.

Buy an issue stock and put it back the way it should be.

I’m woefully unsure about acraglass but I have done some work with devcon putty. It seems to be the same I may give it a go. I’m not opposed to putting it back in a woody when I can find one loose for the right price. It’s hard not to love the old school look. Especially if it’s got a lil red tint to the stain.

With a plastic stock you will need to put in some undercuts to mechanically lock in the bedding to the stock. It doesn't bond to the plastic the way it does to wood.

I’m woefully unsure about acraglass....

Why?

 

[Blkhrt13]

Why?

I’m seeing some posts where acraglass is not as stable as devcon. It was probably a side effect of poor prep work. I’ve never used it as a product. But I have used devcon in the line of doing my job. So it makes me feel more at ease. I’ve seen how tough and durable it can be.

I have used both Acraglas and Brownells Steel Bed for stock bedding.Steel Bed appears to be Devcon Steel Putty.They all work well but Steel Bed/Devcon is thicker and easier to work with.I use Acraglas mostly for repairing cracked stocks now.Acraglas is stable in my experience.It can set up very quickly in higher altitude areas though.

I would be tempted to put it in a wooden as-issued military stock, but there could still be bedding problems with the as-issued stock.
If you want the gun as a utility gun and not as a collectible, bedding the plastic stock would be the economical solution.

I fixed a broken Nylon 66 stock with epoxy but it took two tries and prep with degreaser (both times) to finally get a bond to the plastic.

A correct issue stock will be tight. After markets lack the front stock bolt/pin. It should be directly under the chamber at the rear sight. The rifle sits on the pin and rocks tight against the forearm cap when the trigger group clasp is closed.

I suspect the reason aftermarket stocks forego the pin is due to the large variations in sks's when they were imported years ago. Stocks needed to work for both pinned and screwed receivers, along with older surplus and newer commercial. (This is why you may encounter sloppy fitted wood stocks as well if they weren't paired correctly.) So we ended up with the loosey-goosey no pins instead.

The simplest fix is measure exactly where that stock bolt belongs and install one. There aren't expensive and look ok when countersunk. Or if the stock is plastic you could heat or expoxy a flush steel pin.

Just thought you might find the following interesting if not useful:

In the first link he describes making a lug of sorts for the SKS ramline stock. His SKS uses a removable magazine so the space available in a box mag version may differ but it might still suggest some ideas...
The two videos discuss before and after bedding....
