This wrench looks to be a fine well made instrument.
However an obvious flaw would be it's not compatible with systems other than weaver, as it wasn't designed as a standard 1/4" drive.
(A gross over site in my opinion.)
Because you have no way to torque rings other than Weaver's and no way to torque stock bolts unless they
conform with Weaver standards.
It appears to have been designed by a highly educated person that has never
worked with wrench's off the drawing board.
So unless your 100% into the Weaver System it's an expensive piece of junk,
without modifications and adapters.
Pros: Nice looking unit
Cons: single use
