Hello NitroX the EAW mount I was talking about is a swing mount and is a kind of standard in Germany now. At the
front part of the mount is a sturdy pivot that takes all the forces of recoil. The rearward part ensures alingning with the gun. All parts are CNC- machined to tight tolerances, so little work of a highly competent gunsmith is necessary, contrary to a claw mount, where lots of hours are spent fitting all parts together. The claw mount has most often four, seldom three, claws which engage in their female counterparts in the bases, the two front claws take also most of the punch. But all surfaces have to fit perfectly together or accuracy is just a dream.
A big advantage of the swing mount is that you could change the optics with no big investments as is the case with a custom claw mount. There are numerous used guns for sale here in Germany with an obsolete rifle scope, for example a 4x32, mounted with a claw mount, and you know you have to put a considerable sum into the rifle as you not only need a bigger and more modern scope but also a new mount as well because the old parts will not fit with the bigger dimensions of the new scope. With a swing mount you just switch the upper parts, which are available in all kind of configurations, and that's it.
How about your QD-mounts, are they reliable and take the punch of a .416 ? There is one point I don't like with the EAW mounts and that is their height. They are too high for my taste. I like the scopes to be mounted as low as possible.
Wicked good hunting
