Clawmounts Manufacturing Scope Mount—- The Absolute Zero System

Recently I was asked to test a new scope mount from a young company. After speaking to a former military sniper about this mount I knew this was one I wanted to share with our TFB readers. This scope mount system is called the absolute zero system and I can say without reservation it certainly is that!

The Clawmount System is very very sturdy. In fact it’s the strongest scope mount I’ve ever used or likely ever will use. The Picatinny adapter, for AR’s and in this case my Ruger Precision Rifle, is made of 7075 aluminum while the mount, base and rings are made of black oxide steel. Once mounted the adapter and base are rock solid. When the scope rings are mounted with the scope no part of the unit moves at all even when the QD is used and the scope is changed out.Once zeroed the scope stays zeroed period. I used my Nikon M-308 scope with the one inch Clawmount rings as well as the Nikon AR-223 1.5-6×24 scope with the supplied Clawmount 30mm rings. These were changed out with the same mount. I also used my AR carbine with this mount with a Leupold 1-4 scope as well as the Nikon 1.5-6×24 scope with 30mm rings.

Note the "claws on the scope ring base and corresponding" Claws" inside the upper mount base.

Installation is simple. As normal the user mounts the picatinny adapter at the proper location on the weapon rail and tighten it down using a drop of blue Loctite. The user then snaps in both rings of the correct size. Remove the top half of each ring lay the scope in the rings, adjust the reticle then snug the rings down with a drop of loctite on the ring threads only. Repeat these steps with each scope you intend to use with this particular rifle. While you can move the entire unit from one rifle to another I’d advise having a separate mounted base on each rifle. Doing it this way allows you to quickly and easily swap out scopes in seconds. Changing out scopes is as simple as it gets. On the left side of the mount is a bar which is spring loaded. Depress the bar which retracts the claws within the mount releasing the scope which you simply lift off. Attaching another scope is as easy as lining up the claws on the scope rings with the holes in the mount and press down locking the new scope and rings in place on the base. Once mounted it’s locked and will not move at all.

In the past few weeks I’ve made a good number of trips to the range swapping out scopes as well as the entire unit to another rifle. Again the purpose of the unit is to leave the adapter on the rifle and only change from one scope to another. This is how each scope stays zeroed. Of the many times I changed the scopes the initial zero stayed the same. I never had to adjust my initial zero when changing scopes. This system is impressive and as I mentioned it’s rock steady.


Each system has an MSRP of $215.00 including one set of rings. Each ring size can be added to the order. This system is very helpful to me since I test so many rifles and optics. I highly recommend the Absolute Zero System and I intend to leave it on my test rifle. Not having to re-zero after each scope change is worth a good deal to me. This also allows you to remove the scope when you finish up at the range and place the scope in a protected case rather than leaving it on the rifle and chance damaging it.

This video explains in greater detail how the system works.

    I’m not sure what the advantage is over any solid QR one piece mount (like the GG&G) is, since you need to buy rings for every optic anyway. I guess the pertinent question is how much are extra sets of rings?

    • I’ll have to ask again but I believe about $60 but I’m not 100% on that cost.

      The big advantage is how strong these are and they hold zero so well. I’ve used some pretty well made setups but none have held my zero so well.

      This mount won’t damage your rail when you remove it. The other QD mount scratched my guns from use with the cam style lock. The mount stays locked into the rail and you only remove the scope. It’s much faster and smoother to operate than the others also.

    Interesting idea. I’d like to see a lever locked base vs the thumbscrews though. Or maybe some flush fitting screws, as I don’t really care for the aesthetics of those thumbscrews sticking out.

    • Yep and I wouldn’t be surprised to see them do that in the future. I know they have several new products in the works. The thumbscrews don’t really bother me since I put a drop of Loctite on them so they don;t come loose.

    “New” my behind. This is literally the old German claw-mount (not the H&K one, the sporting rifle one loved by dangerous-game hunters) adapted to a Pic rail.

    • I take their word for it. I’ve also had the former special forces sniper tell me it was new. He teaches now and competes and has one of these on several of his long distance rifles. I’d like to see a photo of the one you mean.

      If you watch the video you’ll see they reference the traditional type of mount you mention, and as Phil says, it is the Picatinny version that is new. TBH the style of the video, the company’s the web site, and the fact that they only seem to offer rings for 1″ tubes in their shop would have had me thinking this was all a blast from the past if it hadn’t just popped up as a new item on TFB. Even the squareness of the mount suggests the early years of CAD!

    Looks cumbersome, but if you change scopes a lot (or have a really nice scope you want to use on multiple rifles) then I can see how this would be a helpful time-saver (& ammo-saver :-).

    Personally, I’ve found that a good laser boresighter is enough to get you within a couple MOA of zero without needing to fire the rifle, which saves range time for other stuff. We usually need just a few shots to get a new scope dialed in exactly where we want it after it’s been boresighted.

    • It’s really not cumbersome. I know it may look that way at first. Like I said I change scopes out a good deal so it’s very handy for me to use.

  • Dave

    Not the newest or most innovative ideas, the Europeans have been playing around with this concept for a long while though usually integrated into receivers or dovetails, but it looks executed well enough at a decent price so points to them on that, though I’ll stick to my Spuhr ISMS’.

  • David Harmon

    I didn’t realize changing optics that often was a thing….

    • Chad Henry

      Switching to thermal is getting big also.

      • David Harmon

        I guess so, I don’t own one. Not for those prices.

  • Yep it’s a claw mount. There is no fitting required by a gunsmith on the reviewed system.

    When properly installed, claw mounts are generally considered the best quick-detachable system for scope mounting: the cleanest looking, the easiest to operate and the most accurate in returning to zero. But, it is not an off-the-shelf, bolt-on system; claw mounts must be custom-fitted by a skilled gunsmith.

    I have this mount. The difference in the two designs are the tappers. This new design offers “preferential wear”. Meaning the more you work it the tighter the tolerance gets. I shot my deer with it this year. It’s great if you want to protect your glass and switch to iron sights in a pinch.
