Thank you for all the help.

Bookmarked!

Excellent Data. I've been using Seekins 30mm lows and was hoping there was something available even lower. Now I know where to look. Thanks!

It’s unfortunate this beautifully made rail is so high. It incorporates an integral recoil lug, but it’s really high.

This is for the low nightforce model. Very nice setup, strong, light, simple

Kingston - are those Ken Farrells on the scale aluminum or steel? What do you think of them? Thanks for the great thread.

Aluminum.

Ken Farrel rings are absolutely quality. Their design sought to minimize height, weight, and the general massiveness typically associated with picatinny rings. The result a particularly svelte design. They’re almost in a class by themselves where that’s concerned.

For lightweight, low profile applications, they’re ideal. KF rings utilize a single crossbolt style clamp. I find this much easier to manipulate than the dual socket head cap screw design utilized by APA and Seekins. This is something to consider in applications where the optic will be removed with any frequency. Another bonus is that KF rings fit both Weaver and Picatinny slots.

Seekins are really work horse rings. They’re well made, reasonably priced, but blocky-chunky.

APA rings are straight sexy, but not as lean or low as KF Rings.




The one caveat with KF rings is as follows...

If you,use a torque wrench you’ll need a T-15 bit with a long reduced shank.


Like this.





The hex portion of bits like this will bugger up the countersunk holes on the upper ring halves.

Seekins 30mm LOW

Seekins 1” Rings fit Weaver/Warne style bases! Seekins’ larger 30mm and 34mm rings will only fit picatinny rails.

Only the 1” rings fit both.

As far as bases go you won't get lower than Warne steel weavers
I milled the slots wider and deeper and added extra slots to match picattinys
Something you need to watch is the ring claws fouling on the receiver ring, these SWFAs needed the claws ground

Brian,
Thanks for assembling. Nice to have all this info in one spot.

Couple of comments.

Some rings (see pics of Seekins rings above) are designed to seat solidly on the top of the rail (aka the base.). For these rings, "height above the top of the rail" is a meaningful number.

However some other rings, maybe most (see pics of Warne rings above), are designed to seat on the left and right "male dovetails" of the rail. For reasons to be explained shortly, I call the imaginary line from the point of one male dovetail to the other the "datum." For these rings, one can slip a piece of paper between the mounted ring and the top of the rail. For these rings, 'height above the "datum" ' is the meaningful measure. Note that because different rails can have different dimensions from the "datum" to the top of the rail, a measure "above the top of the rail" depends on the ring AND which rail is used when the measurement is made. Obviously, this confuses the issue when trying to compare one ring of this style to another.

Granted, the differences may not be all that much, but it seems this thread is about exact dimensions and finding the "new record low."

My point is you really need to consider how the ring interfaces with the rail. In addition, depending on with style of interface, the height above the receiver ring (which is what we REALLY want to know) may depend on the height of the top of the rail from the top of the receiver, or it may depend on the height of the "datum" from the top of the receiver.

"Datum" heights above the top of the receiver ring can be measured. It is not too difficult, but it is best done with some specially made fixtures. I usually measure rings from "bottom of the saddle" (lowest point of the scope tube) to the "datum."

Finally, in the first post, I have never seen Leupold QRW rings with the dimensions given. I find those dimensions for Leupold QR rings, a completely different system than Weaver/Picatinny. I may be wrong, but I don't believe Leupold ever made Super Low QRW rings.

Best,
Gun Doc

Lots of good info.

Thanks
