So I had never owned both at the same time until recently. I had and sold a TT gen 3 xr when they first came out and got into zco after but always wondered the same thing so I got another TT 5-25 to compare to try and answer this for myself.
I have 2 ZCO 5-27’s, one mpct and one mpct3. I also have a 420 with mpct2 which isn’t part of this topic but would probably be the last scope I sold if I had to get rid of them all. It covers a lot of bases!
I have been shooting the mpct3 on my dasher most of the year since I put it on, I was one of the first couple with that reticle to come out of CS tactical when released. I didn’t think you could get better glass than ZCO’s even having owned a TT previously. Along with S&B kahles and others. I really like the mpct3 reticle it has a lot of tools and somehow doesn’t get in the way. I have noticed for matches I do miss some small marks the top 2 mils of the tree, say if I’m trying to hold .5 or 1.5 elevation and some wind it’s kinda open space. Also, I can’t say it has cost me anything but the open dot at a mil isn’t quite as precise of a hold and covers more target than a hash mark does. Pretty minimal gripes. Glass is awesome, parallax is plenty forgiving, turrets are very good. Overall this scope has been my favorite combination of features.
Enter the TT gen 3 xr to do a side by side. Glass is awesome, I’ll stop short of saying it’s better, parallax is very forgiving, turrets I still don’t know how they make them so good! Reticle hasn’t convinced me yet that it’s better for my intended use, although it covers a few more holds in the top 2 mil of the tree by having small dots at .5 & 1.5 without getting in the way.
Back to glass. I compared side by side multiple times now from morning, mid afternoon and dusk with a west to northwest facing range (for lighting reference) and observed from 100 out past a mile. At 1650 yards there is a small structure with a lot of electrical boxes and what not around it that is great for comparing resolution at that distance. Both scopes can easily make everything out and if they were targets could engage and spot without issue. I will say the TT makes out edges a little sharper and colors seem a little more defined, this was in morning and afternoon light. At 515 yards which is where my main target is or at least the one I seem to favor, is a 6” plate on a T post. Both scopes can make it out with plenty of detail and clarity. I think it’s reticle more than it is glass quality, but the TT seems to have a better view of the plate, especially at dusk, I attribute it to being finer than the mpct3 is on the horizontal bar and wind holds even though center dot is bigger. At 400 yards on KYL rack the TT seems to make things out in more detail, the zco can get there but I have to spend a little more time on the parallax knob to dial it in. This is being very picky, it is plenty clear to do anything without issue it’s just when really studying fine details like 1/2” bolt heads I can pick it up.
All this to say, I thought within first couple days I had made my mind up, my end goal is to get my dasher and trainer matching scopes with it being TT or the ZCO mpct3. But I just can’t bring myself to sell the zco yet to get another TT. I’ll probably shoot them some more this fall/winter and see if I still prefer one or the other.
Glass: too close to call IMO
Turret: TT better unless you need locking
Customer Service: ZCO is awesome can’t say on TT. When I used ZCO CS my scope spent more time in the mail than at their shop, and they overnighted it back to me!
Reticle: I like them both a lot get what fits your task better or what your eye likes, but look through the mpct3 in person not on paper.
