Got some in today after a long wait (For both 30mm and 34mm scope tubes).
Anyone else use these yet?
They are like the signature Zee rings, but better with the ability to add or take away 5 to 40 MOA.
I'm a happy camper!

Comes in a cool Plano (Pelican like) box



That is a +20 and a-20 insert--Sorry for the fuzzy pic.

What ring spacing do they assume?

Assuming your rings must be exactly 4.75 inches apart at the center of the ring.
They actually give the offsets for other measurements.

I really like the concept of these and would give them a try but for the height. They just don't make them as low as I would like.

Not a fan of dual clamps...seems easy to get them out of alignment.

What kind of problems have you had with the Burris design?

I don't use windage adjustable rings, so I havent had any problems. It doesn't look like those inserts pivot like the original signature design that are round on the bottom?

Yes, they do pivot.

How can they? the original inserts are hemispherical and can rotate at will. These look basically flat on top!!

I agree, not sure how a flat insert can pivot. The originals basically acted like a ball joint.

New design.
They can pivot up to 5 degrees.
The old Signature ZEE's can go over 35 degrees.
FWIW if you wanted to add like 50 MOA it is less than 2 degrees.

What do they weigh?

The 30mm 1.25" height weigh 7.0 ounces on my scale
