Geissele Super Precision Optic Mount – Return-To-Zero Test

Lead Engineer Neal McKillips discusses the Geissele Super Precision Optic Mount.

They even had BE Meyers build them a special laser to test this thing out. How cool is that?

    great mounts, great company

    Some Bobro lunatic will show up to point out that people who don’t use Bobro are smoking crack. Awesome mount.

    Great mounts – I’ve mentioned in comments before, but I handled them at SHOT this year. The mounts would probably need to be lightly tapped (by hand) into place on some rails, as the lugs are a VERY tight fit.

    While I expected the mount to zero when finger-tight… the loss of zero when one mounting screw was torqued more than the other was a little surprising. Granted, these aren’t QD mounts and I personally make a habit of torquing my own scope mounts, but hopefully this is something they mention in the manual to avoid angry customers who do things like 1/4 turn past finger tight on one bolt, and 1/8 turn on the other…

    Great looking mount. Geissele makes an excellent product, and I am sure this mount would serve anyone well. I would like to see the same test with some minor modifications though. I would like to see the same process with the same tourque applied to both cross bolts.

      Agreed, I would’ve liked to have seen it done to the recommended torque specs since that’s how it would be mounted and remounted every time, and I would like to see this after undergoing recoil for X amount of rounds. It’s a good looking mount though and I like the direction that this is going. Would like to see comparative tests with throw lever designs.

    This is a very “layman’s” way of testing this, and does demonstrate good repeatability, but isn’t terribly quantitative, particularly the way they present it. This is how I used to test repeatability and boresight retention 15 years ago. It would appear that the mount is repeatable to ~.5″ finger-tight and well within .1″ when tightened. This would equate to about .1 mrad/.33 MOA and better than .019 mrad/.065 MOA respectively. That’s pretty sweet…. I’ve seen this mount and talked to Bill G. about it. He’s really knowledgeable and it is pretty impressive and no doubt one of the finest scope mounts available. I wonder though, it’s really any better than a Badger or other quality bolted unimount subjected to the same test.

    Regardless, I’m glad to see more options and people who really care about the quality of their products.

    For empirical testing we had BE Meyers make this laser to eliminate all unwanted variables, except we are just going to guesstimate the torque for no apparent reason and watch the monitor as we walk the laser back onto target.
    Using a Torque Wrench would have shown the RTZ capability much better than a box wrench. The box wrench will not RTZ consistently in the field like a Torque Wrench would as seen while walking the laser back to center as the crossbolts were tightened.

    • Will I Am says:

      While this should have superseded my comment, the Geissele mounts are gorgeous in execution and no doubt will perform and RTZ repeatedly if a consistent torque is utilized, I just found comedy in the method.

      • WWKG says:

        I think he was going for the fact that due to them being so well made that there is no need to use a torque wrench. I believe that was in their SHOT Show video explaining the mounts them selves in more detail.

  7. Pat says:

    From an engineering perspective, this video is a joke. Leave the laser on and adjust the torque until its back where I want it. I can do that with a cheap set of rings.
    It would be impressive if they turned the laser off, put it back on, and then demonstrated that level of repeatability.

    • Jon says:

      I agree with you. I love Geissele products and their strive for innovation but you can clearly see the guy watch the monitor and tighten the box wrench to the point where the laser was approximately spot on to the original zero. If he had done this with the laser off or with no view of a monitor I would definitely commemorate Geissele for a “true” RTZ mount. But until there are independent tests I guess we will just have to speculate.

      • Deider says:

        Being a engineer at Geissele Automatics I can assure you that this video is not a joke. These scope mount repeat better than any other mount on the market. Just ask the elite military groups from around the world why they buy Geissele products. Hands down the best!
