RWS DBL Lockdown Mount Issue


Looking at RWS’ New Double Lockdown Mount

Here’s a quick question.  You are going to play tug-of-war with someone bigger and stronger than you.  You will both be pulling on a smooth steel pipe.  Now you can either grip the pipe with just your fingertips, or you can grip it firmly in the palms of your hands.  Which would you rather do?

You’d want to grip it with the palms of your hands to have as much surface area and force exerted on that pipe as to prevent it and you from moving.

Consider this analogy when you look at RWS’s new double lockdown mount.   The “bigger” guy is the rifle, you are the scope mount, the scope is the pipe and your hands are the rings.  If the rings are not perfectly smooth, allowing for maximum contact with the scope tube, it is like you trying to hold the lead pipe with just your fingertips.  When the rings are perfectly smooth, usually accomplished by a process called “lapping,” then the maximum surface area of the rings can properly grip the scope tube like your hands gripping a steel pipe.

I’ve been trying to work out why the new RWS double lockdown mount does not work.  Granted, RWS should have used a larger top ring, but there are thin rings that hold scopes on 30-06 rifles, so I’m not completely convinced that is the only problem.  Then I took a look at the markings on the scope tube and I realized why the mount doesn’t work, and will never work no matter how tight you try and make it.

There are literally ridges in the scope rings that prevent the full surface area from engaging the scope tube.  Actually this is pretty common with scope rings.  Leapers adjusts for this manufacturing flaw by installing “scope tape” on all their rings.  This actually works, even on the RWS double lockdown mount, as I robbed some from a perfectly good Leapers mount and installed it in the RWS mount to prove my theory.

I’ve attached some photos below for your review with captions on each to demonstrate the issue.  As for what mount to use on the new RWS T06 Rifles.  I’ve mounted an Accushot 1 piece, heavy duty, mount to my 34 and it is holding without issue.  You have to remove the screw in the back of the RWS receiver rail and then you can utilize the new deeper stop-pin hole to secure the Accushot mount.  This works very well and I’m now truly rock solid with my 34, drilling 1 hole groups one after another at 10 yards.

I hope this helps others solve their issues with the new RWS rifles and the RWS double lockdown mount.

RWS Double Lockdown Mount - Shooting Results

RWS Double Lockdown Mount - Shooting Results at 10 yards due to scope slippage - These are 2 shot groups, the lower group is while sighted with the reticle on the center of the target. The top group is will aiming about 3 dots high to compensate. New groups with the "fixed" mount are ragged 1 hole groups at 10 yards.

RWS Double Lockdown Mount - "Pressure lines - 1"

RWS Double Lockdown Mount - Notice the dark lines. This is where the rings "gripped" the scope tube. Because the rings are not perfectly smooth, they have less surface area engaging the tube. That is why they don't hold the scope without slippage.

    Rick;
    Great work with this review and all of your reviews. I purchased a new RWS 34 with this new mount and Lepers scope and could not figure out why my shots were inconsistent. Once I saw this review I looked and I had exactly the same problem.

    Thanks

    John

    • I’m glad this was a help to you. I’ve dropped the RWS mount and moved to the Leapers 1 piece heavy duty accushot mount. That has solved my issues so far. The 34, with a little initial TLC has turned into one very nice shooter.

      Cheers

      Rick
