CZ 527 .223 Scoped

I have also used the Picatinney CZ rail for my 527M, which is a different beast with the fixed iron sights. I removed the rear iron and tried a few scopes, first a WalMart Simmons with supplied CZ rings,

But that scope lost lock and wandered everywhere. I was gifted a Bushnell scope that was quite good, and tried the Picatinney with Weaver Low Mounts, which came out looking like this.

A Marbles folding rear sight was added, courtesy of my local gunsmith in Mesa, and you can see how low the clearance is on the scope bell. Bolt handle clearance was tight.

So, yes, the Picatinney rail CAN be useful, even though I've removed mine, and went with straight irons.

Have fun with your new blaster, and post pics when done, please? Like that putty idea.
 
For reference, here's a CZ 527 .223 Cal. Varmint Kevlar with a Weaver 6-20x40mm AO Grand Slam and
CZ Rings, Medium (.555").

EAJ, Nice. How much bolt handle clearance do you have with that setup? Are you using the original handle that came on the gun? I've been eyeing a Grand Slam but wondering if that slightly over-size magnification ring might cause me to have to raise the scope a bit more (on a CZ with the somewhat high bolt throw) than the objective would otherwise require.
 
Best set up I've seen or shot is with CZ rings and a Leupold FX II 4x33 fixed scope. I didn't think I would like a fixed scope until I shot one. I have one ordered now along with a set of CZ rings to go on my 527 7.62x39

Thanks. My head is filled with putty and that is why I thought of it. :wink:

I will get out my good camera and get some good light and post. I hope to sight it in this week and get ready for a little trip on October 11.

The bolt handle clearance hasn't presented any issues for me. I'll try to take a photo of it this weekend and post it. It's the original bolt. :)
 
I am cursed...

I just sent this email to CZ USA:

Dear CZ USA,

I received my CZ 527 30mm scope mounts in the mail today. Thank you for getting those out so quickly.

I immediately took my rifle to the gun shop the sold me the scope because mounting and bore sighting is included with the scope.

Joe at the gun shop was nice enough to take me back and show me how it is done and let me do things. After we get the eye relief the way I want and bore sighted he tells me how to torque the scope. I have bought a new Wheeler torque wrench from them, and per his instructions I work back and forth, zig zagging torquing the screws.

Suddenly, POP! Two screw heads come off. He takes the torque wrench and compares it to another and says that this thing is way off. But the rub now is that I was doing it, not them, and it is now in my lap. He finds two odd screws from a used can of screws. He takes the scope off, starts all over and remounts it. Then he only had torques the screws, clearly afraid he might pop one.

So, I go home just sick to my stomach. New rifle, new scope, rings with three different kinds of screws in it. Did it hurt my scope? I have no idea, I am new to this and trusted them. Of course they say it couldn't have hurt the scope.

I need to order at least 8 new screws. Do I need new mounts? I don't know. I am on my own now.

What do I need to order?

Please help, I wanted this rifle ready for 0ct. 11, already have the plane tickets bought, I am just sick.

Interesting, I used the CZ rail that I purchased from CZ and a set of Weaver rings on my CZ527 in 7.62x39. The scope is a Nikon the model I not sure of as I'm not at home right now but the bolt handle clears nicely and when I took it to the range it took only 5 shots to zero it. I did buy a set of the high CZ rings and the bolt handle wouldn't clear the objective bell at all.
 
Well, that sucks.

I bought (and am using) Warne meduim rings. There is a recoil lug of sorts - a screw threaded into the base with the head protruding to act as a lug.

When I first mounted the rings with a Nikon Prostaff, I also used a Wheeler wrench and tried to torque the rings to the 25 in-lb recommended by Warne, and crushed the scope tube. Not sure if it was the wrench or rings but when I mounted my Refield Revolution, I only torqued to 15 in-lbs and all is well.

Sorry to hear about your troubles, but you'll get it sorted out. I did, but it was trial and error and the lessons were not inexpensive.
 
Well, I emailed CZ, Wheeler Engineering, and the local gun store. Guess who comes through?

CZ USA!

They are sending me some new screws.

I am hoping the screws gave way before the scope was damaged. Since I am new at this I have no way of knowing. The tube seems okay, but I have to take it back out and look it over.
 
If there are no dents or creases in the tube, the scope should be fine. If those CZ rings are like mine, they are steel and will be fine. You may find that your scope now has superficial cosmetic "rings" on the tube from over tightening of the ring screws. You will probably never notice them unless you take your scope off. I would say that you are just fine.
 
Sirgilligan;

I'm glad that CZ came through for you, that's typical of the high quality customer service they're known to provide. No, I strongly doubt that there is any damage to your scope. Remember, scope makers realize that the rigors of hunting are going to be a factor in their products. Therefore, any modern product certainly should be rugged enough to withstand far more than the stress of an over-torqued screw, let alone Leupold. Leupold is widely regarded as making a very tough product, above industry standard by a noticable margin.

In the future I might suggest that you simply contact Talley for rings. They have a phone number on their website & will talk to you. Tell them the gun & the scope, they will send you the rings. If, for some reason they won't work, Talley will take them back, no questions, and send you something that will.

Thanks all. I took the scope back off since I will be getting new screws all the way around anyway. The tube on the scope looks good and after I rubbed it with my hand a little you can't tell where the rings touched it.

Wheeler Engineering contacted me and I couldn't get it through to them that the "gun smith" (notice the quotes, imagine me doing it with my hands) said that it was off. They just kept saying the only way to break the screws is to over torque them and that I shouldn't do that. I gave up. I guess there is no way they could have a "bad" wrench slip through. :)

So, I am going to do this all myself when the screws get in. I can't do any worse than what I have already done with the experts guiding me!
 
FYI:

CZ USA gave me the numbers for torquing the mounts:
15 inch pounds on the ring screws that attach the top part of the ring to the bottom.
50 inch pounds on the side screws that holds the ring to the action.
 
Just finished shooting the 527 CZ.

No issues. 45 rounds. No cleaning, no cool down
35 gr Hornady Superformance Varmint
55 gr PCM bronze.
62 gr PCM X-TAC
68 gr Black Hills Match
75 gr Hornady Superformance Match

All grouped less than inch at 100 yards

Shooting off of truck hood with sand bags.

Scope doing great. As it got darker we fired up the red dot and kept shooting.

As we changed ammo the groups moved vertically, not horizontally, you have to like that.
 
Very good news regarding your getting tight groups even with the above 55 gr rounds! I have not gone above 55 gr in my 527 and would have thought the barrel twist rate might not have "liked" the heavier rounds.

Now I will go ahead and see if my barrel can manage the heavy weights.
 
I am relieved we got this done, it was a learning experience. This rifle has a 1 in 9 twist.
 
Nice.

Getting this rifle scoped can be a challenge, and for me it was a lot of trial-and-error. Glad to hear you got yours sorted out, with just a little pain. :)

Mine likes 50gr bullets. I can't remember my load off the top of my head, but I believe it was Hornady 50gr SP over Benchmark. Grouped really well out of my carbine at 50 yards - I haven't had a chance to shoot 100 yards yet.
