Just ordered up a 527 for my .338 barrel. Took the 420 on the 300N out to 1150 a few days ago, very impressed!
I broke down and got on @CSTactical 's list for a ZCO 527 MPCT2
I see you had the dream as well
You're very welcome! Have a great weekend and let us know your impressions after you run this ZC527
I would use it. Degrease thoroughly at the very least. The ZCO is a heavy scope and I had mine slip in a Spuhr the first time I mounted it.
You're not actually going to shoot that and get it dirty, are you ?

Ummm, Richard/Mike.......we gotta talk.....
I've never used such a thing on scope rings. I'm intrigued if it actually works or is necessary. I understand the theory of it. I've used locktite retaining splooge on R700 Actions for the scope rail to the actual action. Helps as a "fake recoil lug' also helps to make a "gasket" when using steel rails.
I'm suprised that you had issues with spuhr mounts. I've had my NF on my TRG-42 for a long time with 0 slippage, but then again it is a lighter scope with 6 scew design holding it in place....
I just followed the ZCO instructions that defer to the mount manufacturer....Spuhr,,,,,and had no slip or problem...

I’ve seen him shoot it, but it’s so nice it doesn’t get dirty ?You're not actually going to shoot that and get it dirty, are you ?

I just used isopropyl alcohol. It worked well.
It was probably operator error. I took it apart and tried again and I haven't had a problem since.
And Spuhr recommends the rosin
Isopropyl works great. I also agree regarding use of rosin, it's cheap, easy to find (any store selling sports equipment will have it, Academy or even a Wal-Mart), and easy to use. Helps with grip and also protects the finish. There's really no downside. You don't need it, but why not?
There is a mistake in this manual... It should be written 3.39 Nm, not 33.9 NmFrom the ZCO manual:
Hey that's pretty cool, do they have a corrected version for those of us who suffer from presbyopia (can't read things up close)?
LoL, I did see that. Think I'll stick with my bifocal safety glasses.
My old man always complains about not being able to see shit, I'm thinking about getting one for him.
How many Mils are you guys getting with just 20 MOA mounts, or are you guys going 20 MOA rail/20moa mount to get 40 MOA?
I run 45 MOA in my .338 and I gets me full 20 Mils on my optic, figuring why not go for broke to get most of that 36mm tube.

After zeroing my ZCO420 at 100yards with a 20 MOA rail and a Spuhr SP 6001 mount I had 21 mils of elevation left.
Hey guys I just received my 5-25 mpact2 and would like flip up covers. Please don't throw things as its probably been beat to death. I went to tenebraex site and ZCO wasn't listed. Anyone else make good covers???
You can figure out how many mils you should get from most scopes by finding out the total elevation of the scope, divide that in half and then add about 3 mils per 10 MOA of cant (it's actually 2.96, but 3 will get you in the ballpark).
Therefore, if you have a scope with 28 mils of travel, divide that in half and you have 14 mils, put on a 20 MOA canted base and you'll now have about 20 mils of total elevation available to you, use a 20 MOA mount on a 20 MOA base and you have a total of about 12 mils of additional travel which would yield about 26 mils of elevation you can dial, but if you dial the full 26 mils you are at the extreme limit of the scope which some have noticed some optical distortion. However, ZCO claims to have resolved that issue with their 36mm tube and optical design, they are supposed to have some of the best optical performance while at the extreme end of the elevation. ZCO also offers 35 mils of total elevation, so given the above formula you divide 35/2 = 17.5 and then add 3mils for every 10 MOA of cant until you get to the limit of the scope which for the ZCO would be almost 60 MOA of cant.
I highly recommend Aadmount's caps - http://shop.aadmount.com/Flip-Up-Cap-Set-ZCO-ZC527-5-27X56mm-CAPS-ZCO56.htm
I like them better than Tenebraex, but I also like Tenebraex very much
We have the Tenebraex caps back in stock, I'm working on filling the back orders right now and should have some left over

Sweet. Excited to get the caps on these bad boys. Makes me uneasy without them.
On the scope elevation, I've got a 6mil (~20MOA) Spuhr mount + the Impact 737r which has 20MOA. I have no problem with the 100yd zero, and have elevation to spare even out to a mile. I'd definitely go this way in the future - I don't see any downside as the optical clarity doesn't seem to degrade any noticeable amount to my eyes at 100yds. ZCO definitely seemed to nail this aspect.
Aadmount caps for sure. There's photos on my 527 in my post history if you want to pull them up.

What height rings are those? High 1.26" or Medium 1.1"? I am about to drop the hammer on a 4-20 going on a new build, and like rings, not 1 piece mounts. I like to keep the scopes as low as possible too.
@MarkLeupold What kind of add on grip are those in your rifle? I have a Tikka and something like that might work? Thks
So, the base stock is a B&C M40. I drilled some (3) holes in the grip and epoxied in some threaded inserts. I then made the grip out of "oven-bake clay" and formed it how I liked it. Cook it according to directions and it's kinda like a polymer when it comes out. Bolt it on and rock and roll.
I get a lot of questions about it. Kinda unique.

I hadn't seen any on a ZCO yet, they look good! I liked them on my Steiner and it seems like they mount up the same way. Nice and clean
