Signatures are a great way to fly and I wish all Manufacturers offered rings that wore eccentrics. It is an unobtrusive way,to mechanically center a scope's windage and maximize it's elevation travel,if only because you have to arrange the first,to yield the latter.
Now that being said,Burris fasteners have been dog schit for decades and they continue that "honor". To further complicate matters,the Zee's are typically amongst the worst of their worst,in both sizing and "quality".
They ain't all that warm/fuzzy on a static system,which one hopes to leave alone and about the last choice as "QD's" go. If you're facinated with mounting glass,removing it and remounting it again,ala the Alabama/Texas Field Of Dreams Ploy...you will be farrrrrrrrr better served by sourcing a different route. The Zee's will puke in short order.
If you gotta [bleep] with schit in sucha manner,it's gonna be tough to trump Leupie PRW's,as they repeat exceptionally,as a function of their design,with it's beefy surface area and increased number/quality of fasteners. Their nomenclature is a misnomer and yet they're vastly superior mechanically,to their QRW lash-up,being more robust and far more unobtrusive.
Now if you were to cite the application particulars,it'd save a whole bunch of [bleep] around and you could be assured you rung the bell,right out of the [bleep] gate. So which receiver,stock and scope? Knowing that,you can have GPS coordinates to the Watering Hole.
Again,Zee's are absolute dog schit [bleep] junk,as a means of glass swappin'.
Hint.
(Addendum: for GPS coordinates)
You certainly don't want Zee's,scratch the notion.
Pretty much any base with a recoil cross-slot can be pressed into effective service and I've yet to puke a Weaver base,but they suffered soft fasteners for a goodly spell,which are easily upgraded and nudged to Torx.
There's about a bajillion cobbled Mousers on the Planet and lotsa schit don't align there,which very usually incorporates base holes. You may have the one and only,that's interfaced exceptionally,but odds are...you ain't.(grin)
So far and away the best melding of rugged/reliability,unobtrusive lines,quality fasteners and a viable means to chase concentricity woe(s),the DD Signatures are a very tough route to whoop. It'd certainly be my first move,because it's without compromise and you've 40MOA on tap,to chase concentricity with.
It'd of course be a 6x42 Show and better yet,wearing M1 ele. You'd then be capably armed to fend whatever is flung at you and be afforded the merits of a stree free mounted glass of repute,that's mechanically centered in it's saddle and leaving lotsa opportunity on the erector.
Shouldja' run into serious concentricity woe,you can always pad the base proper,to eek even more ele latitude.
There ain't a move you cain't make,with sucha system and it's ring spacing,conjoined with stress free tube alignment,will make huge strides in both the overall longevity of said glass,as well as it's zero retention. The upside being,there ain't NO downside.
Win/win.
See how easy it is?!?
You've been led to water.
Hint.(grin)
