QD scope mounts

[PhilSN12]

It’s a one piece mount that I’m after as I really wouldn’t trust qd two piece mounts returning to zero. Do you change between rifles or just switch scopes on the same rifle?

Each weapon has its own scope and I switch the thermal between them.
QD mounts per rifle with standard optics - HW100 .20 Warne, .17HMR Warne, .22LR Burris, .223 American Defense & 6.5Creedmoor American Defence.

I’ve just done this for my C50 between 223 and 17HMR. I got Britannia QD mounts and they are working a treat. Not a perfect fit so just remember to push them forward before tightening. There is a good diagram as well to help work out which height you need...

Are you able to straighten the levers on these once there tight?

 

[Pete6.5]

You don't have to get mounts with levers you could also get good mounts like nightforce and a torque wrench and it will be pretty repeatable.

You are right and I do that with my thermal as I use that sight on all my weapons.
But the ease of using a QD mount means less buggering about.

I suppose so if you are swapping in the field but at home it's just as easy either way.

 

[PhilSN12]

I do swap in the field a fair amount, but even at home I would rather have QD's; it just works that way for me.

 

[Andydorset]

Sportsmatch QD OP91 is fantastic, have them on all my scopes bar one.

 

[PhilSN12]

I wanted to get a set but I prefer screws, clamps, etc., to be on the opposite side to the bolt handle. My friend has a set and there is no problem with the bolt hitting the levers, its just old habits die hard.

Can you not flip it round and achieve exactly that? Don’t think there’s a front or back so they could go either way?

 

[PhilSN12]

It has a spirt level at one end.

You are right, I stand corrected!

Same as me, I intend to be swapping around in the field so the idea of dropping loose mount screws and with the potential for rounding screw heads with the frequency of on and off I think levers or thumbscrews will be the best option for me.

Has anyone with lever QD mounts tried them on different rails to see if they would need adjusting to account for minute tolerance issues or do they cope?

 

[PhilSN12]

Yes, no two rails are the same, even from the same manufacturer. Thats why I still use the standard Hik mount on my Thunder 2 as I swap it between rifles. The QD mounts are on the dedicated scopes.

 

[markymark]

I’ve got and used Spuhr, ADM, la rue, sportsmatch, leupold. All do there job of QD and repeatability very well indeed.

But as mentioned you will always get some variation of different rails, so if you are using the QD system across different manufacturers you are best of using a QD system that incorporates twisting levers such as sportsmatch (and others) so you don’t have to keep changing the tension of QD arms via a nut as seen in other systems.

 

[PhilSN12]

I have Warne mounts on two of my rifles and they are very good.

 

[Mike996]

I used the Leupold QD mounts on my Leupold scope and once tightened the levers can be pulled out and lined up in any position.

 

[kenbro]

I don't believe you can use calipers to check how two different rails conform to picatinny spec. And then there is the mount itself (does it conform to the spec).

I'm not sure of right terminology (not being a native speaker) but the "datum points" are on the slopy part of rail and there is certain relations between measurements.

Practical example, you have two rails that conform to spec, and two QD mounts one conforming and another not. It's completely viable that the conforming mount will tighten to both rails with "equal pressure" on the QD lever. And the non-conforming mount will be too tight on one rail and loose on another.

My thermal has two over centre levers to clamp to Picatinny rails and these levers need adjusting when I swap between two rifles. Inconvenient.

Yep, the nut(or winged lever) and bolt clamp through-bolts are definitely easier than the over-centre lever versions….

Thinking back to the Drone Pro with its over-levers mount, it was always a pita to get the same fit across three different rifles rails. In the end I changed it to a Kevgun mount which used nuts.

All of the nv/thermal scopes* I’ve had since have had nuts and a couple with hex socket heads…. None have suffered any repeatability issues. If I swap from day to night scope when up a high seat, I’ve got a thumbwrench in the jacket pocket along with a couple of 1/4” drive sockets and hex’s to cover all eventualities.

*Scope-wise I’m talking Drone, WT75-3, Pard008, Pard SA, Senopex, Zulus across a range of rifles from air, rimfire and centre-fire. Dayscope-tube format-wise with the Recknagel Poly Levers include Photon XT’s upgraded with the Pentax camera lenses (accounted for a lot of foxes, rabbits n rats with those in their time) and generally, Zeiss Diavari 6-24*56’s.

Those Zeiss have a fairly chunky ‘under turret’ and using the separate Recknagel rings means I can get away with a lower base height and better cheekweld on a standard stock. Using a one-piece just adds an unwanted, and unnecessary, extra layer of height as I’ve found using Saddlemounts on the R93’s

Just stuck Thumbwrench set into ‘Goggle’ and it’s the coloured ally jobs I’m talking about.

And inconsistent, unless the levers have clicks or something for the adjustment, and you have written down how much to adjust.

I guess most QD mounts have gotten away with bad design (non-conforming) because traditional optics don't have "profiles" or such and it's a PITA to use same sight on several guns. For me digital sights are the first to be really used on more than one gun.

These levers have a screw that passes through the slots in the pic. rail. The other end is threaded with a spring and nut.
To adjust, the nut is pushed ( Against the spring) out of its retaining slot and then turned whichever way necessary to get correct tension.
Adjustment is one flat of the nut each movement.
Too much messing if in the field at night.
Not that I need to change sights in the dark at night.
