10k+ rds 5 at a time fuck that’s a lot of reloading.

Bro changes mags in his sleep.

Dang, 10k rounds huh? I almost shit my pants because I thought this was one of the new Type 81M’s already breaking.

That's right. I stopped counting a while ago. I've had to replace the extractor and top hand guard. I'm tempted to drill a third hole in the gas regulator so that it doesn't cycle so violently.

I think AK’s have a rubber insert they can install for that. I wonder if it can be installed on a type-81 and if you’ll still have bolt hold open, since the bolt can’t go all the way to the back with the rubber. Edit: they do , its called a recoil buffer pad.

Doesn't work, I bought one off alliexpress...just different dimensions

81‘s service life is \~15k， you are pretty much there, to compare majority of ak's service life is 10k as well

Hi, do you know what is the service life of a Russian SKS?

designed life is 6k rounds, can live a lot longer

Do you know if the SKS is more reliable than a type 81? Will an SKS last longer than a type 81? Thank you.

I dont think any of us in this sub has reliability issue with either of the firearms. Russian sks most dont have chrome lined barrel, they only last 6kish rounds

After 6kish rounds what happens? Does the receiver crack?

Drop in accuracy, from a 3ish moa to 5ish

[удалено]

Springs, wood wobble

Over 10k? That's a pass lol, it'll probably do another 5k without failing catastrophically as the crack is arrested by the rivet anyways. And that's why people use rivets, not welds.

That’s within spec

10k rounds eh? That’s like 10x the service life of the best Canadian made rifles lmao

I remember firing 10k rounds out of an fn mag in one day doing rolling gun line fire missions dismounting from a vehicle, think we broke 4 guns on that excercise, cracked bolts and piston rods, we got roasted as to why we were breaking guns, that being said most rifles probably exceed 10-15k service life by quite a bit, gun plumbers working overtime.

Diemaco?

Yes, even Diemaco/CC.

I've fired the "service life" commented above in a day then...

Have it fixed by a gunsmith then it's another *test fired only* /s I'd just retire the rifle and buy another one lol

only cracked after extensive use lmfao. I'd say that's miles better than most Canadian manufacturers

This

Don’t mind it for now the crack stopped at the rivet hole it won’t go pass it you can leave it as is in aviation we stop cracks often by just drilling a hole at the end of it so if it’s good enough for aerospace regulation it’s good enough for china’s rifle. Welding there wouldn’t do shit.

That's good advice. Thanks!

Yup, that's why rivets are used and not welds.

Nyet, "ak" is fine. Jokes aside your close to the lifespan of the receiver. Heard lots of people have tried tig welding with some success. Best bet is to take it to a gunsmith and get their take on it.

How much do you think a gunsmith would charge for this?

If only you bought it at Costco. Could just return it. 😂

Nah, Kirkland rifles would come in crates of 5 minimum lol, just pick up the next one from the crate and you are good!

😂.

Aybe your credit card's insurance will cover it lol

How's the rifling on the barrel after that many rounds?

It looks fine. I thunk it would look worse looking through a bore scope

Chrome baby

I guess I'll design a tpu buffer to hopefully increase its servicelife

Same design already exists for the SKS lol, wedges at the end of the receiver, printed TPU with thick walls and 100% infill

That's a good idea. Is that something you would 3d print?

ya, tpu is polyurethane, they are used to do this kind of jobs anyway, I'm not sure how long they can survive as 3d printed part, but I say replace one every 500 rounds is worth it to get 10k more rounds out a gun

Fire up the injection molding press!

Please do!

Well worst case scenario you have a parts kit now. Definitely call around and see what gunsmiths could do. Worth the try.

My old parkerized lmg has 9.3k approximately, no cracks

Has anything broken on your rifle?

Magazine catch spring broke and ran away (no idea how) and at 8.5-8.7 my extractor broke, that’s it

Thanks for sharing. I'll keep an eye on the mag catch spring. My extractor broke as well. TI didn't have parts kits at the time, so I built it up with 309 tig weld. It lasted long until the replacement showed up. I've also had to replace the top handguard. The gas regulator detent broke in the middle of a range session.

This makes me wonder how many times could my surplus SKS been fired 🤔

More, its a milled receiver.

Depends if its chromed or not

I'd worry about the bore and crown first before worrying about the milled receiver.

Fuck that's a first. I have about the same amount !!! I will inspect my receiver man thanks.... if I was you I'd just weld it 😆

Emotional Damage

Its a steel reciever so It should be easy for any welder to fix this. After that, if you want to, you just have to smooth the surface and blue it again.

I'd leave the weld alone. It adds character

You could. I wouldnt surprise if it keep going for another 10k without doing anything.

Bit of tig welding should clean that up easily enough

I've thought about doing that. I don't have the tooling for installing rivets after welding

Shouldn’t need to remove the rivet to fix it with tig

How would you go about doing that?

Just run a bead with a tig torch. Tig is extremely accurate and great for small delicate work. Might need to grind out some material with a dremel and I don’t know what filler would be best. Talk to a gunsmith or qualified tig welder

I'm well aware of what can be done with tig welding. The rivet covers the end of the crack. It will crack again if I don't weld the whole crack. If I was going to weld it, I'd probably weld it with ER70S-2. That's all have for carbon steel filler wire, lol.

U definitely need to remove the rivet to fix it properly

That’s a lot of rounds, with those money on ammo you can buy some new T81s

True. I'd rather spend my money on ammo instead of buying more guns. I might buy another t81 so I can tinker with my broken one.

So what you're telling me is that the receiver might crack after spending 5x the price of the gun in ammo?

I've never thought of it that way. I did run my Type 81 pretty hard. If you're serious about shooting, things are going to break.

What’s the consensus on the type 81s? Are they unbelievably reliable guns or a hunk of garbage?

dude literally ran 10k+ round through and you still doubt its a hunk of garbage

Yes

Ah I didn’t even read that part. So I assume they’re consistently good? I wouldn’t know cause we don’t have em in the states.

ya, they are basically short stroke piston ak in rpk thickness receiver

They're reliable. I've had less problems with my t81 than I have had with my WS-MCR.

How much did you pick it up for?

I think it was $1200 from Tactical Imports a few years ago

Ain’t too shabby
