Just opened the little package that came with my 9,3 and lordy those rings are stout! They're almost heavy enough to help soak up some of the recoil.

Bill,

They're a bit brutish, but they do work rather well.

I think CZ used the nose metal from an Abrams Tank to manufacture its CZ 550 Rings. They do, however, work. I ended up buying a set of Talley Steel Rings for my CZ 550 American in 7x57mm and gave to old ones away to a fellow in Texas. I thought they were a tad on the heavy side, but they also looked like hell. One of the posters on these forums came up with a great idea to make them look a whole lot better. Take a dremel tool with the wire brush attachment and wire brush the matt black finish off the rings and then polish the outside of the rings up. Go back with a good, penetrating cold blue and blue them. Just a thought for you. The bottom line is, they are stout as heck and they do work. Tom Purdom

I'll take ugly but stout over pretty and flimsy any day.Jut put a Leupold 4X on the CZ and those rings look like they're welded on.

Bill !
If you go to www.warnescopemounts.com
You will find that they make rings for your 550. I think you can get Quick detachable rings if you want.
I have a set on my fullstock 7X57, work great ...tj3006

By the way, they make um in Clackamas Oregon, bought mine at the factory.tj3006

Thomas: Didn't realize Warne was in Clackamas.

Bill, what kind of ring and clamp screws came with your CZ rings?

They used to all have slotted heads, and the ring screws were not hardened, which made them liable to shearing off. But I'm not sure what they are nowadays.

I think, but cannot remember for sure, that the rings I got with my latest CZ rifle had torx or hex headed ring screws, and slotted clamp screws.

On my first few sets of CZ rings, which came with all slotted head screws, I had my gunsmith change the ring screws to hardened 8-40 torx heads, and I replaced the clamp screws with hardened hex heads.

sloted and yes be careful when torqueing!!!!!

They were all slotted. They didn't feel soft, but who knows?

Yep they are on janzen road, I am local truck driver, and I get that way quite q bit.And I get around town enough that I honestly know the inventory in most of the gunshops better than the guys that work there, and thats no bull !

Bill, watch the torque on those screws.

IMHO, best bet is to head to the hardware store and get metric torx head replacements for the ring screws and metric hex head replacments for the base clamp screws.

Based on hard-earned experience.

Get some Talleys. They look fine are the lowest around and work like a charm. Their detachables will absolutely return to zero if you want to go that way.
