If it were me, I would talk to whomever it was that made the scope and if they have a US facility and agreed I’d send the whole damn rig in as is. Rifle and all, then ship them some ammo. Give them the best possible chance of figuring out what is going on and why.

Don’t know for sure. The company didn’t tell me. They told me it was a fluke and nothing I did caused it. (The first time it broke)
If it's the lens by the turrets, basically under the rings, makes it even more likely you are over torquing the rings.
How have you verified that your torque driver is accurate?

So likely the parallax lens didn’t adjust anymore either? As I think that’s the lens that is just forward of the turrets.
Here is a pic from old nightforce literature, but the idea is the same on many of the brands.
I agree. But I’ve checked and even went lighter the second time. I’ve never heard of the lenses cracking but the turrets operating fine and the parallax moving fine. I’ve been using a torque spec higher on other brand scopes with the arc mount with no issues.
Nope. Moves and adjusts fine. Never binded up or anything.
Now that the OP discovered it's a cracked lens on the forward side of the plumbing, I think it's even more likely something is out of alignment. It's also possible the manufacturer had a few anomalies and the cracking is a result of that.
Or it could be a cursed scope.

And for those that like to do math..............Where's @Baron23.
Ted posts the equation used to compare clamp force of multiple smaller screws to a single larger one.

Can't post in the right forum.
Doesn't know the difference between your and you're.
Can't quote a post properly.
Are we sure it's the rings and the scope?

Oh, and clearly there's a tolerance issue and its failures are likely due to thermal expansion rate differences. The glass is shrinking slower than the tube.
And the box cover is right there.
So now it has me curious....ZCO is a great scope. But do they have temperature issues going from hot to cold?
Living in Colorado and having owned 3 with a 4th on its way, I've had no issues going from hot or warm to cold af. Small sample size but potentially relevant
Larger sample size considering everyone we shoot with.
I literally posted how I've never heard of a ZCO issue the other day. And now this.
Edit: The good news, it appears ZCO has Zero issues dealing with warranties. See what I did there?
So the thread st
Maybe it was the glass incorrectly spec’d or bad quality from their supplier. ZCO could be completely innocent in this matter. Or there could be an assembly issue. Who really knows. They’ll more than likely correct the issue in the end and get OP a repaired or new scope.
Hopefully OP wasn’t on some thousand dollar hunt or had a national competition. Or something of that nature. That’s where I’d be upset.
sometimes shit happens. I’ve had an ATACR dead on arrival, two PM2 malfunction, etc.

Yeah I'm just purely curious now.
It happening to dude's optic once, ok, whatever. Twice with the same thing assuming what hes seeing/saying are right, thats just fucking weird.
I've used Hensoldt, Leupold and Nightforce optics in less than ideal conditions and at times extreme cold (Hensoldt) where they came with some sort of special grease in them and extreme heat (Leupold/NF) where they did everything from sit in the direct sun with a 115 ambient temp and then go through a cold night in the vehicle, or outside and I never even remotely thought the temperature shift would do anything to them nor did it ever.
Having this happen twice on the same optic is just odd.
I agree it's odd that some how he managed to get not only one scope with an issue, but two.
Shit happens, but how the manufacturer responds and handles the situation makes a world of difference. Curious to see what comes of this after ZCO looks at it. Regardless I wouldn't let this deter me from following through on my purchase. Should I have any issues with it, I sure as fuck won't air it out here. Unless left with no other choice like that dude and his NX8.
If I notice anything odd caused by temperature swings, I'll let ya know man lol
Like I said, was just curious. We may have found the ONE scope they made that does this.
Or, since I'm not sure anyone uses these deployed and/or in extreme conditions (never know, all sorts of random shit was there) maybe we somehow found out that they dont like temp shifts because no one thought to test that? Or again, its the 1 in a million that does this. Or OP forgot to tell us how he dropped the rifle on the scope 72 times between shots.
More or less just now curious if this is a variable.
When I was a teenager my cousin accidentally broke something literally every time he came over.
So there always is that one guy...

Pretty sure OP said the manufacturer didn't replace his scope the first time, they repaired it. So if the (hypothetical) flaw remained present, it might not be so improbable that the failure would recur.
That's a common denominator but there are others.
1. Same scope tube.
2. Same scope mount.
If the common denominator of the same guy were the most probably cause, we should also see the same fault with the other scopes.
Can anyone answer this?
What are the extra front mounts used for? Red dots/reflex?
Could the extra mount be causing the problem?
If it's the scope on the far right, has the OP installed one of the extra mounts?

Knowledge is power 100%. But to come to the wrong forum, say my scope broke, provide no detail or photos, and drag it out is just retarded. This thread should've been made after the scope was fixed again, and then saying "ZCO warranty is GTG".
Or if they didn't fix it or gave the run around, air the grievances and then have ZCO come in and give their side of the story.
This was honestly a dumb thread and OP should feel bad. A few isolated instances won't cause me to worry about it.
I think the OP didn't want to deal with the fallout if he came in here saying it was ZCO.
It helps get to the root of the problem quicker though. Would you go to a car forum and post "$30k+ car having issues." "Hey guys, I have this warning light on but not going to say which and I don't know what it means. Can someone help me diagnose it?"
Oh sweet TT’s can stand up to spuhr mounts now? That’s great for the program"to avoid the pain in the ass sending it back is".
TT
FWIW, I have ZCO's and TT's in Spuhrs. Zero issues. Ever. Rings torqued to 22 inch lbs IIRC.
should have bought a leupold
My car window has a crack for the second time, im using BF Goodrich tires on it.
Haha, I was going to say the same thing. I have had 3 different PMIIs take a heaping steaming dump in me over the years...
I thought a few years ago when I was interacting with the company’s warranty repair technician that it felt nice that there was a name and customer service assigned to the process. Then I came to the hide one day and seen an entire thread praising how awesome the technician was which he was as far as I could tell. But then I was like, there has to be a lot of warranty repairs for something like this to happen. It’s not something you expect from the “gold standard.” Other brands, sure but not the gold standard. I just thought that was odd.
Haha, I guess so...
Fuck it, I'm leaving it like that.
You must have not had the patience to make it to post #201
That’s where all this hypothetical shit show really starts to come together
I think……
People have nothing better to do, sadly. Everything turns into a dumpster fire nowadays.
The first time, but I seemed to aquire a taste for it after a few times...
But their warranty was great!

We should rename this thread “buy once, cry multiple times”
It's been beat to death already, so I won't repeat the obvious, but do you make a habit of ignoring mfg direction or is this a one-off situation?
Unfortunately, this is the one off situation as it makes no sense. If you have followed Ted long enough and have observed his design principles, you may know what I mean. There is pretty good reason why ARC is not much more successful than it is.
From the note you are making, I dont think you are with me tho, so stick with the "mfg direction".
