Type 81 SR Serious Quality Concern

View attachment 625201View attachment 625202

120 rounds of norinco copper washed white box ammo, wish I hadnt sold as much as I did - anyway
check out these photographs. the stock was tight to the receiver before firing.
after firing, at the end of the day, we noticed play in the stock, where you see the gap in the first picture
upon further inspection inside having removed the recoil spring , you can see there is a crack the width of the stock .
emailed TI saying I can provide said pictures, so. yah. what yall thing they gonna do/is gonna happen with this? rifle kinda not serviceable with stock as is now broken from shooty lol

Thanks for sharing, would like to know what TI will do. I believe there'll be more and more such a failure and rifle replacement doesn't address the root design issue.
 
One thing the bfiles mod doesn't take into account is expansion. If someone takes the rifle out in the summer vs winter, the wood screw just isn't going to cut it. Could potentially put undue bearing stress on the wood. The m6 sleeve is a way better solution imo. And the gnutz fix i think is bad as now you're crushing the receiver together so the geometry is changing slightly. They are pins for a reason. The correct solution without changing the stock in my opinion all of the following together:

1) the m6 sleeve with machine screw plus blue lock tight
2) leave the pins alone if your stock isn't cracked
3) this is the hard one because nobody has figured it out yet. Need an attachment point into the receiver through the Pistol grip.

Does your deck, fence or anything else with expansion not hold up during the cold/hot?

I know mine are fine, other then being out in the harsh conditions for years and years on end until they rot and then need to be replaced
 
A good mechanical connection of ones choosing located in the B-files fashion is a good start. I like who ever suggested removing an 1/8" of wood on both sides where the pins go through and gluing in some metal plates drilled to match the weak locations of the pin holes.

That's true, and someone pointed out another solution which to me it should work very well: "Drill a hole straight down into the reciever plate", "This screw would then go straight down into the pistol grip".

Better fixes probably mean harder to achieve. It'll be hard or no way to turn back and possibly void the warranty.
I tried to reinforce the stock by putting a screw to the back of the receiver where there is a hold in the recoil spring lock, but the brass screw head just broke off when I try to hand torque it. I then put some steel epoxy in the hole and there is no turning back. Link to the original post.

Think twice before doing any DIY fix.

Measure twice, cut once.....
I was the one that suggested you could fill it with expoxy if you didn't want to peen the brass.... :)

bonding and insetting some metal plates to the stock where it slides into the receiver, and getting the holes in the right place, is not within everyone's skill sets that's for sure.

I think I'm gonna talk to my millwright buddy and see if he can make something exactly like this

Should have come from the factory like this. I don't understand how the manufacturer thought that 2 mm of wood alone would be a good solution.

Thank you for the recommendation, I feel a lot better now. Last thing in my mind is how to remove the epoxy if TI provides a reinforced stock to be installed. Maybe I could hammer it out, or rotary with a copper brush.

I don't think it would be to hard to remove most of it with a drill and a bit of skill.
 
Quick question about the type 81 SR, would it be possible to replace the rear trunnion with another type 81 trunnion or an AK trunnion. I wanted to mount an SVD stock but yea not gonna ruin a good stock on a bad design.

With enough money anything is possible, you would likely be further ahead doing a barrel and gas system swap from a SR onto a regular T81 or LMG without the weird slant cuts at the back of the receiver.

you will need to cut a pretty chunk of wood to reshape it. i thought iwas pretty close to the chinese svd: ndm but not at all as svd and ndm are interchangeable ...
 
strange that a couple of dealers are selling these, usually TI sell to dealers towards the end when they have a handful left. could this fiasco kibosh sales?
 
Id be freezing the sale of them and retrofitting what stock is left. They say they've only observed a 1% failure rate, but i suspect a large percentage (double digits) of the purchasers are like me and havent even fired the gun yet. And many who have fired it only have a couple hundred rounds thru it. IMO its not a question of if they will break, but more so when?

TI already sold out of them in a Canadian specific Type 81 SR with the LMG barrel and a Dragonov style stock, despite a known issue with the stock pin sockets cracking and going to be needing a fix of some kind.

Tactical Imports said:
Factory investigation revealed it was due to improper alignment of stock during install, if the holes weren't lined up properly then the pins would crack the stock as they'd just be pressed into the wood when installed. However it is a very rare issue, less then 10 units affected
 
Lol ya i aint convinced by TIs statement at all.

And now we have winter and nobody will shoot them.

I have lost my faith in this company.

I will just find a solution myself, not with that screw thing, it has to look and feel right.

The reason we are getting that story is that he would have to provide a complete new end stock with associated hardware in order to fix the problem. Both upper and lower areas of the stock towards the receiver have to be modified.
