Home Forums Hunting & Shooting Hunting Optics Picatinny Ring heights and M700 picatinny rail heights listed

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?

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.

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

Height is 0.750”
Weight is 3.0oz

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.
