I have a CZ 550 in .505 Gibbs. What QR rings options do I have and will they be strong enough for the .505 recoil? I have used Lynx (B Square) rings in the past on my .458 and they were fine. I really dislike the look of Warne rings with the top join rather than side split rings like Leupold etc.

Be careful. I had the same gun in 458 Lott. After less than 50 rounds, the mounts sheared sending a brand new Swarovski scope to the ground.

Larry, what mounts did you have?

Despite their vaunted reputation I've been very dissapointed with a set of Talley QD's I put on an AHR 450 Rigby. The rear ring would not hold the scope ( vx-6)securely, it would creep forward and the front ring would hold the scope but slip forward also. With some adhesive on the rings it appears to be holding better. Bought a set of CZ rings which I will the hardware on as a next step. Also interested in other folks suggestions.

I use steel Talley QDs on my big bores, including my CZ 550s, one of which is a .458 Lott and another a .500 A-Square. Talleys are vertically split rings.

No problems with the Talleys, and they hold zero when removed and replaced.

Contact Morris Melani at Alaska Arms if you want the best QD rings for the CZ's

Thank you all.

HDU:

I don't remember off the top of my head. I can find out. I can tell you they were not low end rinds.

I will second Phils recommendation.
The Alaska arms rings are very well made.
I have 2 sets of Morris' rings and 2 sets of Talleys. I am thinking of selling the Talleys and replacing them with the Alaskan arms q.d. rings.

If you have concerns/questions give Morris a call. He is a great guy to deal with!

Nothing works as well as this on a CZ 550 Magnum.
The secret is the 65 inch-pounds on the two main mounting bolts, the "clamping screws."
If you want QD you replace the main bolts with automotive quality metric socket head screws,
and you carry a hex wrench in your pocket.
Nothing better exists:

Could I ask who makes these rings?

Oops, thought that would be obvious: CZ makes the best rings for the CZ 550 magnum.

They may not be the lowest or the prettiest, but the latest ones from CZ-USA in Kansas City, KS, are prettier and lower than some of the past versions.

Here is an example of one with my Quick-Detachable-QD lever, not just a QD lever,
it is a QD-QD lever:

Thanks RIP. That looks like a solid set-up.

A second vote for steel CZ rings. I also lap the rings and leave a little lapping compound on the surface to absolutely hold the scopes in place. It may mark the finish slightly, but the scope never moves enen on the biggest kickers.-Rob

I bet Rob has busted some Talley-for-CZ rings on heavy kickers too, like me.

The pictured QD-QD rifle-ring-scope combo above
(Rings made by CZ for CZ 550 Magnum)
has shot groups as small as the equivalent of 3-shot 0.160 MOA at 50 yards and 0.3 MOA at 300 yards:

Talley failure on CZ reported by bobby 7321:

Buffalo...

My dad had 3 buffalo on license. It was one of those animals he had always wanted to hunt. I also had heard how addicting they could be and wanted to get a taste for myself. We were very excited the first time we were on the fresh terds from that same morning.
Now before I get into the saga of the buffalo, I need to go off on a small tangent. You'll understand why once I explain.
My dad's .416 was a CZ/ AHR custom job. It was something me and my brother got for him for his 60th bday. I had ordered well before we made the decision on where to hunt, I just knew we would in the next couple years so I wanted to get him something cool for his 60th. AHR did an excellent job, no complaints at all, and my dad loved that rifle. He decides on a Z6i 1-6x, illuminated reticle for the low light possibilities on the trip, and goes all the way down to 1x for elephant or other close encounters. Then we decide on Talley CZ rings. Solid reputation, seemed like a great choice. Well we had a year to practice with the rifles. Him on the .416 every couple of weeks, and me on the .375. At least a couple hundred rounds each to prepare. Off the sticks, off hand, open sights, etc...

About 3-4 months into it, the talley rings break. They must have been slowly failing, the thing that alerted me was when I went to the range and I hit the berm 200 yards out, and about 20 yards over my target.



You can see what happened. The rings and scope moved with the recoil and sure enough cracked along the inside of the screws. Knowing Talley stands behind their products we call them up, they saw "huh" basically and send us out a new set. This time the QD release. Same exact rings, just have the lever instead of the screw. We figure, oh maybe it wasn't tight enough, or something we had done wrong....
Fast forward to about day 10 of the trip. I look down and I notice that one of the levers is pointing at a different angle that I am used to seeing it at. I turn it down to 1x and look down the scope... Shit... Its way off... Then I look at the rings closely... Exact same issue. The rings failed at the exact same spot. We checked those levers daily to make sure they were tight. First time we thought maybe it was our fault, but this time we knew it was something else...
(hold spot for pic of 2nd set of rings from trip)
I plan to contact talley and let them know that this time the problem cost us dearly... Like I said we had gone about 10 days before finding this problem... In that time we had wounded a buffalo and a hartebeest... Never to be found again. We believe that it was slowly getting worse. I had mixed emotions... first very pissed that this could happen and all the crap and depression about wounding and loosing two animals (not to mention the buffalo was a very serious and dangerous order I will go into next), and then the other emotion of "thank god" we found the problem before trying to shoot a lion, or elephant, or anything else really... Any ways this explained a lot about the bad shooting. Not to say my dad is the best shot around, but we practiced like crazy and things just weren't adding up.
So now I was to use the .416 as a backup with open sights, no problem. He would use the .375... Which would be a problem, for a few days any ways... You see he had practiced with the .416 exclusively the whole time. It had a nice crisp 2.5 lb trigger. The whitworth was a great gun, but had some creep and probably a 6lb trigger... This would make for some more bad shooting. My dad was used to the trigger breaking at a point much sooner that it did, he would actually end up pulling the rifle back and shooting low almost every time... Which is exactly what happened on the hippo, and a buffalo later on.

So moral to the story... Take an extra set of rings, and a scope while you are at it. And if you have a backup rifle, have similar settings for the triggers. better yet practice with it just as much... tough lessons to learn, but now we know. It was unfortunate to loose those animals, but also glad that no one was hurt because of this.

Another member's "Talley Crash" on a CZ:



I have another picture of my Talley Crash somewhere ...

I use Talley QD on my CZ550, which is a 458 Lott. Have had no issues with them whatsoever. After reading this thread though I will keep a close watch on them. Thanks for the heads up.

Rip,

I like your QD-QD lever. Now if we could just fit it in a trap-door grip cap.

Seriously though, The CZ rings are looking better every day. I've had more than one customer recently that has had ring failures with the Talley's on CZ Magnums. We've been using them for years on all of our rifles including the 600 OK's and haven't had any problems. Now we get a spate of bad results and I'm not sure what to make of it. I don't see any design difference in the Talley rings, though I do see where they could easily be strengthened to maybe cure the problems some guys are having. Whether Talley will make a change is another matter.

I've always resisted using the factory CZ rings for a few reasons. For one, they're butt-ugly and clunky. Also, I didn't like the dogleg on the left side of the rear ring being on the clamp instead of being part of the solid part of the ring. Also, they sit high and everyone wants low rings. I have re-worked a few sets in the past, replacing the slotted screws (another loser) with Allen or Torx heads. That cleaned them up pretty nice. I must have over a hundred pairs of 1" rings; every new rifle we get has a pair with it, and I just throw them into a box.

I think that guys also overlook the rings when they are doing maintenance on their rifle. Take a minute to check that the screws are tight and that the scope hasn't moved. Look at the recoil dog-leg to see if there is any change or damage starting to show. You can go years without having to do any maintenance on scope/rings on a small-bore rifle, but the-big bores are continually trying to tear themselves apart.

Stay away from the big, heavy scopes. Some of the Swarovski's are heavy as a damn boat anchor. Again, the laws of physics will win and tear that big, expensive weight right off the rifle. We're talking 416's, 458's and 500's here; you don't need an observatory strapped to the top of a 50 yd. rifle. Use some common sense.

I'm done.

I agree with everything Bitterroot says (except I've never experienced a Talley failure of any kind). I have some of the AHR modified CZ rings and some other sets of the same rings that I've modified myself. AHR drilled out the ring screw holes and rebored and tapped them for 8-40 torx screws. My own just use the standard CZ screw size. The CZ rings are stout, but that's because they're very heavily constructed - I would say overbuilt. Still, I do like them for the heavier scopes.

If you're going to use the CZs, I likewise advise replacing the base screws with hardened hex screws and replacing the ring screws with hardened torx screws. I don't think 8-40s are strictly necessary, but the extra strength the bigger screws provide sure can't hurt. You can find replacement screws at just about any decent hardware store.

As I said, I've never had any problems with Talleys on my CZs, including the Talley QDs on my AHR .500 A2. If they're breaking as shown in these photos, I would first of all suspect that the base screws are not being properly tightened or are loosening somehow. Either that or poor QC or use of poor quality steel (which is another way of saying the same thing) on Talley's part. I will definitely be keeping an eye on mine from now on.
