You don't need to tell me that, my friend.
LOL!
The Norica Omnia is the second time around that this recoil-isolating mechanism has been put forward. The first time, COMETA exhibited the technology in one of the IWA's, but COMETA was wise enough to see that the appeal of the technology would be on the high end of the market, the "upper level performers", and there was a question about the extreme similarity of this version of "Zero Recoil" and the Italian "EffeZetta".
Anyway, that's past history.
To my knowledge, there have been a few TX-200's put into these types of "chassis stocks", but in reality none of them have achieved the results that were expected in matches outside Spain (where the technology comes from).
Modern ways to tune spring guns have done away with much of the vibrations and recoil, but if what you want is a gun that can be held as close as possible in the same way as you would a HP / Service rifle, then the 54 is still your best bet, and the ZR Mount, once Accurized is truly capable of Match grade accuracy and repeatability.
To date, I have put out over well over 200 Accurized ZR Mounts and no scope has died in them. Even vintage scopes.
I still need to find a way to counteract the thermal effects on most scopes using the ZR Mount, but that may be a quite different/difficult and/or probably impossible task without a complete re-design of the mount. We'll see new ideas are floating around in my head, LOL!
Keep well and shoot straight!
