How firm should the wing levers be tightened for these mounts?

On my Kevlar stocked rifle I have 30 mm Warne QD rings & my Leupold 1.5-6 X illuminated reticle scope. I find that after 20 to 40 shots the levers seem to have moved a bit and I am able to tighten them again.

So far the mounts have not come loose as I check them before each range session.

Is there anything particular that I need to be aware of? I leave for my first African / Zimbabwe hunt for buffalo in 47 days.

Warne CZ rings only allow you to use them with levers on the right side.

Set your levers like this and they will tighten themselves with recoil:



Those are low Warne 1" CZ rings that they don't make anymore. They only work with a small ocular bell like on the 2.5X Leupold.

Your higher 30mm rings will be stressed more by your heavier scope.

Still, you should only finger tighten the levers just short of "white knuckle."

If you set the levers properly, pointing up on the right side of the rifle, they will stay tight, or get even tighter.

If you were using standard CZ rings, you could torque the main mounting screws to 65 inch-pounds: Nothing is stronger that CZ standard rings.
They can also be QD with a hex key/Allen wrench in your pocket,
and the slotted head main mounting screws replaced by socket head screws.

Thanks RIP

I was actually wondering if I should PM you or just post on forum!

Here is my rifle & scope


I did not realise that the mounts would tighten with recoil. I thought I noticed a bit of movement when I checked last.

I do have the Warne torque wrench but that is set for 25 inch-pound.

Nakihunter, it maybe the photo angle, but the rear ring looks as though it is to far forward on the integral dovetail for the recoil lug on the ring to engage in the slot?

egle27,
Must be an artifact of the photo, there is only one position where the rear ring may be placed.

Nakihunter:
You have positioned your levers so that inertia of the lever works to loosen it when the rifle recoils.

That is the opposite of how they should be on the right side of the rifle.
The direction your levers are pointing would be correct for levers on the left side of the rifle.

If you will point the tips of the levers upward, any direction above bore axis, the inertia of the levers will work to keep them tight in recoil.

If the levers tighten in a clockwise direction:
Starboard levers must point up.
Port levers must point down.

The opposite would be true for a lever that tightened in a counter-clockwise direction.

I'd like to see the rifle from the opposite side. That rear ring doesn't look right.

RIP my friend - you are not only a good doctor but a budding Physicist! Thanks for the simple & accurate explanation sir. This sociologist has to brush up his high school physics!

Eagle - the rear mount is fitted correctly as there is a side tab that HAS TO fit into a dedicated recess in the bridge of the action. It cannot fit any other way - that is the fool proof design. So it is an optical illusion from lighting in the photo.

I wanted the view from the opposite side, because I've seen two front rings used. It must be some weird lighting trick in the picture because it looks like the rear ring overhangs the port. Neither of mine do, with the same Warne Rings.

Thanks Naki, I thought as much, I have CZ rings (not levers) on my Brno ZKK 600 so know the set up for them. Just had a horrible thought you may have had to grind away some of the side tab to get the ring spacing for your scope to keep that front ring away from the deep set lense in the Leupold.

Different scope in the picture accompanying this post, is it yours or just a file photo? It has the front ring wrapped around the front lense area!

In your example photo above does your front ring tighten in a counterclockwise direction?

If not, it seems both levers should be pointing up. I learned of this myself the hard way a few years ago on some Leupold quick release rings.

Eagle - Yes it my scope & that is the first one which got spots on it (coating bubbled?) & I had to send back to Leupold. When I first wrote to them with that photo they said it was fine. I attached the photo with the repair unit & they replied that the rings should NOT be around the lens! Their instruction on the web do not mention this.

I had a similar issue with another scope on my Mannlicher Schoenauer as that also has a longer bridge space.
