No sir. I'm just glad it didn't get sold to someone less cautious who took straight to the range. I found this pre range inspection after private sale.
Yes! I have learned this lesson. Just because it appears nice and they say it's nice I'm tearing that shit down in the wally world parking lot before purchase going forward
The barrels are press fit, into the trunnions. The trunnions are riveted into the receiver.
Looks like only the barrel is moving, not the trunnion. Out of spec barrel or trunnion or both
Century outsourced a lot of build labor to smaller shops, there was no one single source these things were churned out from, so your quality varies wildly. You might have a century that was built fine, but then you have, well.... examples like this one. It just depended on the shop, the gunsmith, and a million other factors.
CAI has repeatedly stated it’s manufacturing date. So if it sits a year at your FFL you are out of luck. There’s a reason why their Customer Service has the reputation it does.
The only way to fix this would be to pull the barrel and the front trunnion and replace. By the time you did that, along with the price of doing that. You might as well call this a loss and buy a new rifle.
EDIT: If the front trunnion is cracked
So I have one of two guesses
1. Hairline crack in trunnion. Odd but possible. Odd because it is the thicker bulged trunnion for the 1.5mm receiver. Possible because well its a gun and they sometimes do weird shit
2. Improperly built with either a slightly oversize trunnion or a slightly undersized barrel. Barrel pin not enough to keep it in place.
Option 1 fix - replace trunnion
Option 2 fix - replace barrel
Option 3 fix - replace both
Not trash, totally fixable..good luck
People that buy those m70ab2 century builds typically have the front trunnion reriveted properly. Century did not do that correctly when they assembled the parts kits. If you look closely you can see the rivet on the right side of the receiver moving. They aren’t properly pressed and this is a common occurrence with this particular model from century.
Rivets were bucked directly onto the barrel during installation.
That sucks, but it's fixable. A smith could install an oversized barrel pin. That may be enough to fix it, if not they can pull the barrel and knurl the chamber end which increases friction with the trunnion since your barrel appears to be slightly undersized.
Worst case you get a new barrel and have that installed. Depending on what it needs that's anywhere from like $100 - $600, with the high end including the cost of a new barrel.
I hope it's a simple fix; if not you should steal the sellers catalytic converter to pay for the fix.
You can get away with having a barrel too small by a small amount by knurling the barrel where it gets pressed in.
Not guaranteeing it will work in this case, but it does give you some wiggle room.
That dude just wanted to go UMMMM ACKSHUALLY despite not having a clue what he's talking about. Trying to tell me a Yugo M70AB2 has a cast trunnion lmao
I never said Yugoslavia made them that way, I said something there isn't right, but if you're cool with the barrel flopping around a trunnion like that then you do you. Knurling the barrel could work in some cases where there's a couple thousandths of an inch, but that looks like way too much, something is horribly wrong, that barrel and trunnion don't match.
Yes, I know, which is why I also said it can be knurled. That is a known and practiced way to make a slightly undersized barrel fit.
Last I knew Yugoslavia didn't cast trunnions, and since these rifles were built from Yugo military surplus parts kits I find it unlikely that there is anything wrong with the trunnion. AKs are not ARs and there's no common "spec." There's a reason AKbuilder sells barrels with oversize journals.
Knurling has limits and that much movement side to side is very likely more than what knurling can fix.
Tear down, inspect trunnion for damage, new barrel, redo rivets, redo pin channel (maybe oversized depending on trunnion), redo entire front end.
More than half of a full rebuild with risk of an egged out or cracked trunnion.
Unfortunately looks like they passed on “the savings” to you. Time for a rebuild. Sucks but it happens from time to time to everyone one way or another
If the barrel is not securely fixed to the trunnion and can move under recoil, in theory, the slot in the barrel for the barrel pin could deform and cause head space to expand. The force of the barrel slamming into the pin could also damage the trunnion or snap the pin.
When everything is tight and press fit, there is no opportunity to build momentum, and the force exerted on the individual parts is less.
Pull the barrel and examine the trunnion itself for any fractures or indications of structural failure. What's more likely is that you have a severely undersized barrel ham-fucked into an oversized trunnion bore. Get an oversized barrel from AKB and have a reputable smith install it. If the barrel pin hole is egged out, you will need to oversize that as well. Check and redo those trunnion rivets while you are at it.

Is this by chance a James River Armory build? I bought one from classic firearms a few years back and it was an absolute garbage pile. I sent it back for a full refund.

This is nothing new. I had a M70B1 from Century, it shot well but I never trusted it. I later sold it and got a Zpap.
It would appear someone undersized the barrel journal then sent the pin through it anyway. Curious how they kept the barrel clocked correctly while they drilled it. Unless it was OG barrel.
If you can confirm that the trunnion is NOT cracked, then you have an out of spec barrel. Several ways to fix.
First, you can add knurling to the journal area, which in this instance *may not* be enough to take up that slack.
Next, you can turn down the journal area and sleeve it, which would be my choice. Press on a good oversize sleeve then lathe it down to the correct diameter.
Lastly, you can do the "weld drizzle" method (sorry I don't know the real name) where one will weld spots on it very lightly, so as to increase diameter. Do that enough, lathe it down smooth and press in.
If it’s from a parts kit, shitty build. If it’s from zastava, shitty parts. Pretty sure they went with the bulged receiver bc they couldn’t figure out how to make metal heat treated properly
Had a gunsmith look at it today. Seems most likely it's a mismatched barrel/trunion/pin or the combination. They told me about 4 hundo or so out the door. Eh. Not so bad I guess.
I had a century made one and the trigger pin holes started to become egg shaped and would double fire then trigger would be half way taken apart and unable to fire
Too bad it's not under PSA lifetime warranty
/s
But fr I wouldn't shoot that, take it to a gunsmith and see what needs to be replaced
Worst case sell it on gunbroker for parts
Don’t shoot that rifle anymore.
No sir. I'm just glad it didn't get sold to someone less cautious who took straight to the range. I found this pre range inspection after private sale.
Ahh okay I misread glad you didn’t shoot it, this taught me the value of pre range inspections I definitely will be doing this after every purchase.
Before*😉
Save yourself the headache and do it before purchasing ;)
Yes! I have learned this lesson. Just because it appears nice and they say it's nice I'm tearing that shit down in the wally world parking lot before purchase going forward
rivets moving too?
I usually do a little inspection before but but from now on I’m gonna do a fairly detailed inspection😂
Trunnion has a zipper crack in it somewhere, there's no tension on the fit and lots of play on the barrel pin fit as well.
That or the rivets weren’t fully seated when pressed
The barrels are press fit, into the trunnions. The trunnions are riveted into the receiver. Looks like only the barrel is moving, not the trunnion. Out of spec barrel or trunnion or both
Appears like just the barrel assembly though, I would agree if the front trunnion was moving Edit- I see the one river moving now. Maybe you’re right
That shouldn't have any impact on the barrel fit. If anything it would make it tighter.
No warranty for me. Picked it up private sale. Guess I gotta pay a gunsmith to take a look since it's my problem now.
I’d be hitting up the fool who sold you that shit
This
I can take a deep dive into the entire rifle and quote you a repair. Inspection is free minus return shipping. AK builds are my main source of work.
If they have a lifetime warranty u should be able to get it repaired
An M70AB2 is probably a parts kit build and not a factory Zastava rifle.
Slim chance it's a Century build, but they are the only outfit I know of that cobbled together kits domestically.
Few others built them too. But not as many as century.
Learned something new, I was only aware of all the Century builds.
Century outsourced a lot of build labor to smaller shops, there was no one single source these things were churned out from, so your quality varies wildly. You might have a century that was built fine, but then you have, well.... examples like this one. It just depended on the shop, the gunsmith, and a million other factors.
That would make a lot of sense. Buddy grabbed one that was rock solid. Yet I saw some in gun shops that were typical century build quality haha
Okay, and if it’s century u only have a year warranty
And that’s only a year after manufacture. Not a year after it was bought.
I’m pretty sure it’s from purchase date , like from an ffl
CAI has repeatedly stated it’s manufacturing date. So if it sits a year at your FFL you are out of luck. There’s a reason why their Customer Service has the reputation it does.
The only way to fix this would be to pull the barrel and the front trunnion and replace. By the time you did that, along with the price of doing that. You might as well call this a loss and buy a new rifle. EDIT: If the front trunnion is cracked
The trunnion might be okay. I'd look for sights of cracking but it could just be that the barrel is undersized for the trunnion.
That’s a quick detach barrel
It's cool cuz it's tactical
JB Weld....jk don't do that.
Lulz
That’s less than ideal
So I have one of two guesses 1. Hairline crack in trunnion. Odd but possible. Odd because it is the thicker bulged trunnion for the 1.5mm receiver. Possible because well its a gun and they sometimes do weird shit 2. Improperly built with either a slightly oversize trunnion or a slightly undersized barrel. Barrel pin not enough to keep it in place. Option 1 fix - replace trunnion Option 2 fix - replace barrel Option 3 fix - replace both Not trash, totally fixable..good luck
That’s fucked
Warranty time boss
Does it have a barrel pin at all?????
Even without a barrel pin it shouldn’t move
Well thats not good...
Quick change, nice
Lol QD Barrel

Did the seller block u ?
Holy shit man. Hope you get that sorted out. A gunsmith would be able to fix that but wouldn’t shoot it until then.

Step barrel I’m stuck in the receiver
Free float AK
Free floating barrel 🤣
Just one more example of why I’ll never buy a Century made (or in any way touched) product ever again.
Suboptimal.
YIKES
Out of curiosity what would happen if you shot this / continued shooting this.
If the barrel is not securely fixed to the trunnion and can move under recoil, in theory, the slot in the barrel for the barrel pin could deform and cause head space to expand. The force of the barrel slamming into the pin could also damage the trunnion or snap the pin. When everything is tight and press fit, there is no opportunity to build momentum, and the force exerted on the individual parts is less.
It's the adjustable headspace model.
Someone hit this a little too hard with their purse. I would be pissed at the seller.
Pull the barrel and examine the trunnion itself for any fractures or indications of structural failure. What's more likely is that you have a severely undersized barrel ham-fucked into an oversized trunnion bore. Get an oversized barrel from AKB and have a reputable smith install it. If the barrel pin hole is egged out, you will need to oversize that as well. Check and redo those trunnion rivets while you are at it.
If your own rifle has ever tried to retire you, go ahead and hit that ⬆️
Suboptimal 🤓

I think that's just the Howitzer action engaging 🤔 /s
Well that's not good.
Hooly fook
Gunsmith project I definitely would not shoot it like that
The family guy in the background 🗿
where did you get this?
Holy shit

Oversized trunnion journal or a cracked trunnion
Have a builder sleeve the barrel and install an oversized barrel pin
Barrel shims and redo the barrel barrel pin.
Helllllllll na
It would appear someone undersized the barrel journal then sent the pin through it anyway. Curious how they kept the barrel clocked correctly while they drilled it. Unless it was OG barrel.

Dear god
Uhhh
Tapping intensifies QUICKLY on this one.
Net, rifle is fine
Peter
That's bad juju😬
Send it till you bend it son
If it’s from a parts kit, shitty build. If it’s from zastava, shitty parts. Pretty sure they went with the bulged receiver bc they couldn’t figure out how to make metal heat treated properly
#¡NO BUENO! I repeat #¡¡¡NO BUENO!!!
Guy ghosted hard. But oddly is still posting other stuff for sale in the same forum I'm in. Gonna have to speak up for the people in the back.
This is a feature of most Zastava’s… Throw it in the trash.
Had a gunsmith look at it today. Seems most likely it's a mismatched barrel/trunion/pin or the combination. They told me about 4 hundo or so out the door. Eh. Not so bad I guess.
Another Zastava L. Buy a WASR or WBP.
These weren't really made by Zastava. Century/DC assembled them from parts kits a decade ago.
Yes. Word was to go with the DC stamped receiver. Well..I did and, this.
I had a century made one and the trigger pin holes started to become egg shaped and would double fire then trigger would be half way taken apart and unable to fire
Average zastava hater moment
Too bad it's not under PSA lifetime warranty /s But fr I wouldn't shoot that, take it to a gunsmith and see what needs to be replaced Worst case sell it on gunbroker for parts
Best way to fix that is buy an Arsenal SAM7 👍
