SKS receiver moves front to back in stock?

I have a Russian refurb Tula. After putting a few hundred rounds through it and taking it apart twice (once after delivery and once to clean after a few hundred shots). I noticed that now the entire receiver seems to slide back and forth in the stock... It is not much movement, maybe a millimetre... But it's noticable If I grab it by the top of the receiver or by the trigger guard and push front or back. Stock is laminate.

Is this common? I tried tearing it down and putting it back together to make sure it wasn't a problem with my assembly... Still does it.

Anyone have it and know a fix?
 
Check to see if the tip of fore end has a gap between the laminate and the cup attached to the barrel.

I could see mine freely moving there about 3/16" back and forth, so I built up the area with a bit of epoxy putty. There's no movement any more, and the stock is a tight fit to get back together after detail stripping.
 
^^^ did you notice any accuracy improvement after you stopped the receiver moving in the stock and did you build up the stock or the metal cup on the barrel?
 
You can try first to use some cardboard for shims. Paper will not compress, cut a shim from ammo box, wet it with oil. Try and check. After it could be replaced with brass shims.
 
Someone can correct me, but the design is such that for the stock to rotate on and off, there would need to be a small amount of fore and aft clearance, no? Too snug and it would be very hard to remove... Mine is nice and tight top to bottom and so the trigger group holds it snug from moving...
 
Very amateur advice lol. The recoil lug needs bedding. This is the protrusion from the bottom rear of the reciever. You'll see where it sits against the stock. When properly bedded, the front of the reciever should fit tight against the stock crossbolt and the recoil lug should fit snugly against the stock. Bedding compound is your friend. Make sure the area being bedded is free of oil and grease, remove any finish and rough it up. Apply release agent to the reciever. Mix up some bedding compound and apply it to the stock. Assemble the rifle. Hang it from the front of the barreled action and attach some weight to the stocks sling swivel. This will pull the reciever tight to the crossbolt so the bedding compound will set up with a tight fit around the recoil lug. Make sure you lock the trigger group in for this. Once done, your stock will fit nice and tight and the rifle will shoot better.

I added it to the laminate, as I didn't want to be chiseling out the metal if I were to ever change out my stock. Yes, it stopped the fore and aft movement. I did find my groups improved slightly.
 
Whoever told you paper doesn't compress is very confused. Polyurethane doesn't add even close to an mm. Epoxy bedding does.
 
This issue will affect accuracy in any rifle.
SKS' are prone to this, which is why I always recommend pulling in the barrel and stock at time of purchase to check for movement. I've bypassed purchasing rifles that have this issue in the past.

Very true but even a tight fitting rifle can wear and become loose with time and use.

Brass shims people. Brass shims.

This. So simple. Cut apart some pop cans if you can't get brass shimstock. Keep adding behind the trigger until you can't fit any more and the rifle is pushed up snug against the stock crossbolt.

I believe most if not all SKSs out there could benefit from some amount of shimming. IMO this is the easiest and best mod to do if you are trying to get the most out of your SKS.
 
Bedding is a simple, easy task and when done correctly is a permanent solution ljones. If that was too much attitude for you, give midol a try but I won't be piping anything down.
 
I believe we're all amateur shooters here by definition. Unless you're getting paid to shoot in gravel pits that is...
