Edited adding APA 30mm Low .750"

These I believe are the lowest in a picatinny configuration .......

.750's


And Cameron at Murphy's Precision can make a Rail thats pretty low also !

Thanks Ackleyfan! I updated the list. We have a new low!

I originally made this in 2010 and posted it on the old hide. I had to acquire and measure all the various bases. When the hide sold out I baled, but every once in a while I need to reference this list and have to go find it. I figured I'd post it on the Fire, as this is where I spend most of my time these days.

A very time consuming list you did a nice job putting it together ....very useful!

Another option is the American Rifle XLOW M10-1-00-30-20 at 0.79" or 0.20". I haven't used these, but reviews seem to range from positive to glowing. I might give a try.

Nice List. Thanks for putting it together.

Would like to hear your opinions if you do.

The ARC mounts will make you toss everything else away. Don't try them. It WILL get expensive.

Whats so special about them........

Don't mar scope. Takes about two minutes to get rings on rail, scope in rings and leveled with no rotation when you tighten down the clamp. Come in extry low and can sure help eye alignment with a rail and a stock with a lower comb. And have been rock solid on everything I've put them on.

Pretty nice attributes, have you had a chance to weigh a pair?

No rotation is a big plus.

Interested in the weight as well.

Someone enlighten me please. The American Rifle XLOW rings are 0.79" from top of the rail to the center-line of the optic or 0.20". What does the 0.20" measurement/height represent?

Received the following information from American Rifle today. The information won't copy and paste correctly, but all weights displayed are in ounces. The first weight is net weight and the second is shipped weight according to AR.

I asked if the weights were for a single ring or pair and am awaiting a response. My opinion is the weights are for a single ring.

Just got back to the ranch. I'll toss a naked set of 1" and 30mm in extry low and report.

30mm xlow 4.8oz for the pair
1" xlow 4.7 oz for the pair

For comparison sake a set of XTR sigs 30mm in low are 6.5oz with inserts. This is on Wifey's kitchen scale but it'll get you close.

According to AR, the weights listed above are for a pair.

We have a new LOW.

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.

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

And tag.

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

Kingston, this is great info, thanks for compiling it.

One thing - I notice you don't have SWFA rings listed, do you want measurements from those? I have a pair of unmounted Low SWFA 30mm rings I could measure if you don't already have that info. (Offering just for completeness of the list, I know they aren't the lowest by any stretch.)

I went ahead and measured the SWFA Low rings in case anybody wants the info:

SWFA SS-TAC 30mm Low 0.835" or .244", 5.0 oz (pair)

Will they fit Weaver width slots or just picatinny?

Good question, I have only used them on picatinny. I'll dig around tonight to see if I have any unmounted weaver bases to try them on. If not I can at least measure the crossbolt width.

I could not find a spare Weaver base, but measured the crossbolt on the SWFA rings - it appears they will NOT fit Weaver bases, since the crossbolt is 0.190" wide, and Weaver slots are listed as 0.180" wide.

Hope that helps.

Anyone know if the Xtreme Tactical 1-Piece Base for a SA 700 has the same rear height?

https://www.burrisoptics.com/xtreme-tactical-1-piece-base

Anyone tried the one piece version?

Bump to one of the more useful threads on the fire......

Anyone have a weight on the Hawkins Precision Ultra Light picatinny rings, in low preferrably?

Tag again. Great info!

Kingston do you happen to know the thickness of the Burris 2 piece picatinny rail #410635 for the Sako? Im looking for the thinnest one possible if you have any leads. Great write up by the way.

tag

I don't.

Note on this. The Ken Farrell 30mm Low Rings I have won't fit Weaver bases....Pic only...at least the ones I have. I was disappointed.

He must have made a change.

Follow up. I emailed them to see what they say about the 30mm lows for weaver bases. They replied they should work with either.

I've put them on pic and weaver bases and the cross bolt doesn't fit down in the weaver base. When tightened on a weaver base the bottom of the ring isn't touching the top of the lug...there's a fingernail's width between the top of the rail lug and the bottom of the ring on both sides of the ring's cross bolt. With pic bases it sits all the way down.

Perhaps this is intended. I'm not confident it it with only a touch of the cross bolt on each side making contact with the base and none of the ring's bottom touching.

SPUHR HP30-19A PICATINNY AESTHETIC RINGS

They appear to be very well made.

Harrels Precision makes a very nice aluminum picatinny Rem 700 base in either 0 MOA or 20 MOA.

Dumb question: why is everyone so interested in getting the lowest possible scope rings?

i

All else being equal, lower scope heights results in a stronger mount due to the reduce length of the mechanical lever arm (moment arm if you speak in engineering term). The shorter the arm, the lower the stress on the mount.

To me, it is just as important that they be correct height for proper eye alignment with good cheek weld, which makes stock ergonomics a factor. If/when those ergos result in higher scope heights, the strength issue can be resolved with different mount designs, but those solutions typically increase weight of the mounts.

For me, the biggest reason to mount low (or to mount higher in some cases) is to get the best cheek weld and eye alignment. Any other reasons are secondary (to me). The preferred height will vary according to stock design and facial/neck/shoulder/etc structure of the shooter. Using the same stock, pumpkin head needs a different height than pea head.

Lower will use less amount of scope adjustment for zeroing. In most cases it's not a biggie but it used to be a bigger issue with limited adjustments.

Related to that is better line of sight to trajectory. Again, in most cases not an issue. Doesn't change trajectory of bullet, just where it's crossing line of sight.

Canting seems more pronounced to the shooter the higher the mount. Again, not an issue if mounted correctly and leveled when shooting.

As mentioned, higher the mount, the more stress that can be put on it it. There are really good strong mounts now that should make this a non-issue.

For me, fit is it....anything else is not really in consideration for me.

Just because lower is faster for me.

APA came out with new model ring. 30mm set is the same .75 height as previous but the rings are wider...a touch wider than Seekins. Previous APA 30mm lows weighed 3.5 oz, new 30mm lows weigh 4.4 oz. I put a pair on last week and they are very, very nice...and the price reflects it.

Those look good. Not horrid on weight either for their strength.

Henneberger HMS Weaver rings, 30 mm - 3.5 mm

3.5 mm = 0.14" — 18.5 mm = 0.728"
