Rifle Scopes ZCO vs TT regarding reliability and known issues (if any)

[utah_longrange]

Not looking for which one is better optically or which one has better turrets. I'm mainly looking for how reliable each one is and are there any known issues with either?

I've heard people say early TT's had zero shift issues and early ZCO's hard turret issues.

Any long-standing issues for either?

For reference, I have a ZCO 527 10 mil non locking mpct2x and just picked up a TT 525 gen3xr. I'm trying to decide which one I like better but want to weigh any possibly issues into my decision. They will be used primarily for PRS with one or two ELR matches per year. Whichever one I don't like as much I'll sell to fund another one of the one I like. At the moment I'm leaning towards the TT since I like the higher magnification and turrets but if TT has zero shift issues sill I'll pass.

Both are clear ALPHA scopes, They both have teams that stand behind anything that may go wrong. I would say that there would be lots of noise if a significant issue came due to the shear numbers of top competition shooters using them. There were weird things like dropping the rifle and seeing temporary POI shift, but I really doubt these were design issues. Both are nearly identical in magnification (yes the ZCO is 2 X higher). Which retical do you shoot better? That and your use of the turrets should be the factors. Make the decision about which you will use based on which will move you up the leader board.

The people I talked to at a recent PRS national match (some top pros) had all switched from TT due to zero shifts. They shot them when they first came out though and multiple admitted it has likely been fixed since. Just curious if anyone still has noticed this. I shot a Burris XTR pro previous to this and it did have zero shift issues so I do want to go back to that.

I have about 10 ZCO scopes (between 527 and 840), most of them newer (2023 and newer) and I have not seen this issue, but I am not spinning my turrets in competition like they do.

Yeah I was mentioning the TT had the issue, not the ZCO.

Don’t be a poor and get both? If one goes down you have a backup. I wouldn’t worry too much about it. My zco has been bomb proof.

Sorry I was multi-tasking and misread your post. Still, since you own both I would pick the one I shoot the best. In the end as one of our members constantly says, the only thing people remember is how far up the board you are

yeah if you read the whole post you would have seen I currently have both.

I can’t read, but the sentiment remains. Don’t be a poor and keep both. That better?

ha ha, I have multiple rifles so once I pick which one I like both I'll get another.

Honestly you really can’t go wrong with either. Tool less turrets are really nice on the TT. Pick what features you like best and go with that. Lots of guys at the club I shoot at have never had issues with TTs and zero shift.

You’re already off to a bad start by doubting the equipment cause others have had “issues” with that optic.
I’ve been running TT’s for about a decade. When they first came out. Haven’t had any zero shift. Regardless of what platform they were on.
And this is more than a dozen of their optics from 315P/ 525P to 735P


Maybe I got lucky

Have both. have had the tangent fall mid match from my shoulder to the hard dirt floor right on the scope bell. Scope has a pretty bad dent and Didn’t experience any impact shift. It probably has more to do with the mount you’re using (spuhr). Had my ZCO 5-27 15 mil glass crack in the safe once and happened to another friend of mine also. Zco took care of it and haven’t had or seen this issue with the 10 mils yet

That's why I wanted to get more opinions. thanks for your insight. I plan on trying them both out before committing to one or the other.

That is pretty impressive! At a match earlier this year a tripod fell on a buddies ZCO and it jacked up the sunshade. It bent so bad he couldn't get it off. ended up with a zero shift though. I was getting zero shifts with my burris xtr pro's mid match almost every match. That's without even bumping it. I had 3 of them total and all did it. It was always subtle though like a 0.2 mil shift in any given direction. I would start missing right or low and go back to the zero board and it would be off from the morning zero. Haven't had that once since switching to my ZCO. If the ZCO had a larger FOV I wouldn't have got the TT to try out.

With the few I have seen from both brands, I have not had any zero shift issues. For what it is worth, I have more rounds downrange with TTs and currently have three here: 3-15x50, 5-25x56 and 7-35x56. The 3-15x50 is the oldest one of the three and went back to the factory once to get cleaned. That's about it. No mechanical issues whatsoever.

I had issues with multiple ZCO,s ( Parallax / Focus) ................ have had no issues with my TT..

With the thousands we sold from day one, we have not seen that issue with our customer's in North America.

Lord knows we all know about that

Was about to say....lol

The true alpha optic for not shifting zero is undoubtedly the NF ATACR 7-35. Who would even own a ZCO with the NF standing as the clear superior optic

I have had 5 TT‘s and currently still have 3, basically I just traded around to get all with the same reticle. I had one fail at the Punisher match a couple years ago. the windage turret would sometimes dial .1 for 1 click, sometimes none and sometimes .4-.6 per click. It was extremely hot that day, well over 100 and our rifles stayed in the sun a lot, I’m not sure if that was a contributing factor or not, I was just mentioning it. TT replaced the erector set in it and I have had no more issues with any of them. To my knowledge, I have never had one zero shift. I may see the zero change .1 one way or another from one range to the next but I attribute that to DOF more than anything. I think both are fine scopes, can’t got wrong with ZCO or TT.

Unfortunately, in this day and age it would seem QC is not what it used to be and I think this is somewhat across the board, but maybe it always was and Al Gore's interweb is what made everyone more aware, if you belong to Fakebook then you have likely seen the gripes and complaints ad infinitum. The point being, any scope you buy today has the potential to go down at the most inopportune time, yes we can all debate until the cows come home on whether brand X or brand Y has a better "reliability" record but truth be told, Murphy's law dictates that if you bought a scope that had a 100% track record then you would be the first to have an issue. What matters more is how well a company responds and how quick a company responds and to that point I would say ZCO and TT are among some of the best when it comes to customer service and response times, sure you're going to have your one off bad situations (maybe a CS agent had a bad day) but by and large you know you'll be taken care of should something ever happen. Regarding zero shift and TT, others have already addressed, the issue is a non-issue.

I've had a TT525P for about 5 ish years now with the gen3 xr and I love it. never given me a hickup and the tool less zero turrets.... no regrets with this one. fwiw I use spuhr mounts on my rifles for just such reasons. I'm sure many one piece mounts are just as solid.
